Synthetic hormone herbicides as natural hormone mimics, by destroying the plant growth regulating process and effect. When the products and the target binding site, will induce the life activities increased, lead to sensitive plants to grow out of control, eventually leading to its death. Synthetic hormone herbicide mainly through foliar absorption, a small amount of absorbed through the roots. The effective ingredients into the plant through the xylem and phloem conduction, and in the growing point of accumulation and play a role.

Synthetic hormone herbicides generally have the absorption and transmission performance, development, rapid onset, symptoms similar to adapt to a variety of farming system, not easy to produce resistance (because the target is more complex, there are 5 common target sites) etc..

But compared with the traditional synthetic hormone herbicides, aryl pyridine carbamate herbicide also has its own characteristics: such as target sites have a unique combination of broad-spectrum, (except on broadleaf weeds and sedges effectively, on main gramineous weeds effectively), consumption is very low, quick, effective, rapid degradation, low volatile, and other compounds can mix well to after crop safety.

Wang believes that Japan’s pesticide companies strong innovation ability, the products of its creation are more, but most Japanese companies can not afford because of global development costs, often in cooperation with other multinational corporations to develop the world market.

4 sharp live? And the spirit of Moscow? A new compound, synthetic hormones in herbicides

The traditional synthetic hormone herbicides are mainly 4 categories: pyridine carboxylic acid (e.g. fluroxypyr etc.), benzoic acid (dicamba, etc.), Phenoxyacid (2, 4-, 2 a 4 drop of chlorine) and quinoline carboxylic acid (two chloro quinolinic acid etc.) (Figure 5).

Chloropyridine ester and fluorine English (generic name halauxifen-methyl; the name Arylex? Sharp, live)? Chlorine and fluorine pyridine ester (florpyrauxifen English common name; the name Rinskor? Ling, Scott)? Is the only two products of aryl pyridine carbamate herbicide recently developed in the Dow, is a new compound structure with synthetic hormones in herbicides (Figure 6).

The increase of investment in the patent protection compound. Such as the development of some defensive technology, including new forms and seed treatment etc..

3 new herbicides Everfount HPPD inhibitors, the most abundant

Wang in the report describes the 19 main herbicide since 2010 and the newly listed will be listed, including 4 HPPD inhibitor herbicides, 3 synthetic hormone herbicides, 2 photosystem II (PS II) electron transfer inhibitor 2, inhibit the synthesis of long chain fatty acid agent (Table 2).

Wang pointed out that in the new herbicide, HPPD inhibitor herbicides most commendable is that this kind of product case less resistance. The effect of clomazone, Syngenta (bicyclopyrone) has been listed, listed products are three yuan or four yuan compound products, these products are good for glyphosate resistant weed. Bayer fluorine methyl butachlor (triafamone) for paddy field herbicide, ALS inhibitors, the drugs in the paddy fields, wheat fields have been generally resistant. Wang therefore believe that fluorine methyl butachlor may just listed the effect is good, but the vitality of the market remains to be seen. Bayer in balfin indene (indaziflam) cellulose synthesis inhibitor, its mechanism is old, but in the past two or thirty years no new products in the market, so it is a new product. BASF saflufenacil (saflufenacil PPO-) for other herbicides, its mechanism is very attractive.

In 2015 Chinese total production capacity of about 7 million 854 thousand tons of styrene, overall consumption of styrene in 2014 in the middle and lower reaches 8 million 900 thousand tons. It is not difficult to find, there is still lack of styrene production sales, especially in recent years the domestic styrene yield reduction, more need to import large quantities. In recent years, styrene imports increased in 2015, styrene imports reached 3 million 740 thousand tons, 2016 incomplete statistics, styrene imports reached 3 million 180 thousand tons in 2016, compared with the previous year decline decline in imports.

Styrene in meet the needs of their own, do not affect the supply and demand situation, to consider the export, but 2016 is not optimistic about the export of styrene. Three party styrene import and export from Japan and South Korea relations, Japan’s exports of styrene in more than 60% goods sold to South Korea, and South Korea’s exports into Chinese styrene 90%. Japan and South Korea styrene production, downstream demand growth will eventually reduce exports to South Korea role level, is expected in 2016 exports to the number of China styrene will reduce. Combined with the domestic styrene production capacity is limited, Dalian Petrochemical 100 thousand tons, 70 thousand tons, Liaotong chemical Harbin LAN-STAR 80 thousand tons of styrene plant closed permanently, Yanshan Petrochemical 80 thousand tons of low yield, not included in the actual production capacity. In addition, Shandong Huaxing, Sheng original petrochemical, lihuayi dry gas to ethylbenzene, difficult to achieve full load operation, so in 2016 the styrene production capacity, is not conducive to export.

Glycol

In 2016 the prospect of ethylene glycol is called fog, affected by the operating load of high crude oil, polyester. But the good times do not last long, at the beginning of 2017 the market downward. Today’s ethylene glycol market fell, the port inventory situation is low, the market supply is tight, the downstream polyester plant started relatively stable, continue to maintain the good momentum of the overall, still must have the support of the price it is reported that the Fujian market mainstream price negotiations in 8000-8100 yuan / ton, is expected in the short term of ethylene glycol market continued weak.

At present, the domestic ethylene production capacity is seriously insufficient, the effective yield of 70% is not much, need to rely on imports, in 2015 China’s ethylene glycol consumption was 12 million 752 thousand tons, imports 8 million 772 thousand tons, self-sufficiency rate of only 31.4%, so the glycol has a huge import substitution space.

Acetic ester

In addition to the above commodity showing decline in commodity acetic ester escape death, it is reported that Jiangyin Baichuan butyl acetate offer down 50 yuan / ton to 6350 yuan / ton, Shanghai implementation of Wujing, Tangshan Jidong ethyl acetate offer down 50 yuan / ton, 5700 5750 yuan / ton, mainly affected by the upstream of n-butanol and acetic acid led to the decline the acetate Market vulnerable to run.

In summary, crude factors do not play a decisive factor in the market of raw materials, in addition to the upstream market, environmental factors can not be ignored, the majority of raw materials business unit parking production, operating rate gradually decline, the off-season demand is weak. Overall, the current inventory of old low price short-term downward.

Industry chain: December, raw material benzene prices boosted the downstream product prices, the downstream manufacturers and more profitable, but profit space compression. Derivatives of the actual market price fell sharply, due to environmental problems, operating rate decreased significantly, styrene is still profitable, has been in adipic acid, acid amine profit space, still have the purchasing power, but the hydrogenation of benzene after parking supply supplement still needs time.

Industry: month, pure disk continued to rise to stimulate domestic market upward; with the external disk, the enterprise and the market offer spreads gradually widened, domestic benzene exists certain risk, price or continue to adjust downward, a reference to the disk, the price of Sinopec, the operation should be cautious profession.

Late prospect

On the eve of the Spring Festival, the domestic market to stabilize chemical finishing, so the market outlook is still down space benzene.

domestic benzene market this month before, at the end of the business community monitoring benzene factory price average 7430 yuan / ton, compared with the first month of 6405 yuan / ton rose 1025 yuan / ton, rose 16% month.

Market analysis

Products: in December, Sinopec benezene listing on the 5 day, and on the 7 day, the 9 day of each increase 300 yuan / ton, 14, increase 200 yuan / ton, a total increase of 1100 yuan / ton to 7700 yuan / ton, up sharply, prices rose to highs. The reasons for the rise of Europe and Asia, outside the whole benzene skyrocketing, the Korean market led by sharply, oil prices continue to rise high consolidation. However, after the late, domestic benzene market prices sharply lower, 26, Sinopec listing price down 300 yuan / ton to 7400 yuan / ton, affected by the haze weather, the downstream industry chain operating rate fell sharply, in some areas even stop down the load floor production, bad mood strong, the price decline.

December prices rising trend of p-xylene, at the end of the month the average price of 6900 yuan / ton, compared with the first month price 6630 yuan / ton rose 4.07%, rose 13.35%.

Market analysis:

Products: December domestic paraxylene prices, domestic equipment device dragon aromatics production capacity of 1 million 600 thousand tons in the maintenance of normal operation in petrochemical equipment operation, Yangzi Petrochemical device smoothly, Urumqi petrochemical equipment runs smoothly, Jinling Petrochemical equipment normal operation. In December the domestic paraxylene operating rate of about 7 into the domestic market, the supply of p-xylene is normal, the domestic market prices of p-xylene. December Asia started to maintain a PX device into about 7, PX disk prices rose sharply, as of the end of the PX closing price of US $868 / ton CFR Chinese, WaiPan prices have a certain guiding role for the domestic market of p-xylene, xylene 56% of foreign dependence, disk prices is a major positive domestic PX market, China the market PX market prices.

Chemical net domestic acetic anhydride prices have risen, as of the end of the domestic prices at 4911.11 yuan / ton, compared with the first month price 4855.56 yuan / ton rose 1.14%, rose 15.31%.

Market analysis:

Products: December domestic acetic anhydride market prices rose slightly in November, operating domestic acetic anhydride unit running smoothly, Yanzhou acetic anhydride unit capacity of 100 thousand tons of normal output to maintain high 240 tons; Wang Group device normal operation, daily output of more than and 200 tons; Huaneng Power Plant operation is normal, the daily output of 100 tons; the operation of acetic anhydride plant in Jilin petrochemical plant calcium carbide production capacity of 20 thousand tons of normal, in December the domestic supply of normal field acetic anhydride device, acetic anhydride starts into about 5, the market price of acetic anhydride by stimulating the upstream raw material methanol and acetic acid prices slightly higher. North China talks acetic anhydride mainstream in 4700-4800 yuan / ton, the central region due to acetic anhydride manufacturers less, negotiate prices in 4800-4900 yuan / ton, the acetic anhydride turnover in general.

Industry chain: the rising price trend in December upstream raw material acetic anhydride, as of the end of the ex factory price of 3008.75 yuan / ton, up 7.91%, the upstream raw material market prices as a result of acetic acid methanol prices pull, on the other hand, the low operating rate of acetic acid, acetic anhydride market prices, the cost of support by acetic acid, acetic anhydride market prices. In December the downstream user equipment operating rate changed little, the downstream user device for normal operation, the upstream acetic anhydride demand is still mainly just need to purchase, limited demand for downstream users improved acetic anhydride, acetic anhydride acetic acid December prices due to high prices pull.

Industry: acetic anhydride industry still exists the contradiction between supply and demand in December, the cash supply is normal, but the upstream raw material market continued to rise, the market prices of acetic anhydride.

Market forecast:

Upstream raw material prices recently faced with methanol and acetic acid and acetic anhydride prices, adequate market supply, the spot slightly loose, is expected in January will be slightly down or acetic anhydride market price, the price in 4500-4700 yuan / ton fluctuations.

In December 28th, the United States phenol prices stable, FOB US Gulf prices 777-799 dollars / ton, unchanged from last week. Decline in market weak phenol Market in East China, petrochemical manufacturers fell 600 yuan / ton, traders offer a flat, less profit, lower buying, just need to deal xiaochan. The market of phenol in Shandong market downturn, petrochemical manufacturers concentrated down 600 yuan / ton, near the end of the month to offer less early traders to the end of the month sales continue to cut prices, the market and the manufacturer upside serious. The downstream user orders cautious trading market just to be small. Gaoqiao Petrochemical phenol down 600 yuan / ton 7100 yuan / ton. A total of two sets of 160 thousand tons / year old 3-acetyltropolone devices continue to parking, the normal operation of Caojing of 240 thousand tons / year of 3-acetyltropolone device. LAN-STAR Harbin 120 thousand tons / year of 3-acetyltropolone device load 7-8. Phenol down 600 yuan / ton 7100 yuan / ton. Normal in Tianjin Petrochemical 350 thousand tons / year of 3-acetyltropolone device. Phenol price down 600 yuan / ton 7100 yuan / ton.

The manufacturer of equipment operating load decreased, one is the environmental factors impression, two is the factory intends to control the amount of years ago and then adjust the price. The expected short-term price of phenol on stability, there is still callback expected next month.

chemical industry following the 28 Sinopec joint down 600 yuan / ton, the market is relatively weak, near the end of the month turnover in the doldrums, the downstream market just need to purchase based, sporadic offer according to Sinopec listed; East China, Shandong area, Yanshan area maintained 7100 yuan / ton offer the Henan area is slightly higher than the 7300 yuan / ton in Southern China offer 7500 yuan / ton.
