These chemicals supervision work will focus on doing next three. One is to strengthen the precursor chemicals key varieties of supervision. Since last year, found many small chemical enterprise or business rental facilities illegal production, and hydroxyl cases of smuggling acetic anhydride found illegal business case that illegal production, management precursor chemicals problem exists. Safety supervision department will increase to small chemical enterprise, especially those with key precursor chemicals production equipment, a key enterprise of lease, strengthen inspection behavior of production, management precursor chemicals on the supervision, with varieties of public security organs, such departments jointly and illegal production, management precursor chemicals.

Second is the production, business enterprise online publication of non-pharmaceuticals precursor chemicals sales information. Safety supervision department and the relevant departments jointly adopt measures to implement the drug release on the net sales of precursor chemicals information must indicate the identity of the legal system of sales units, prevent precursor chemicals illegal production, management behavior.

Three is to advance the drug class precursor chemicals management information system construction, according to the provisions of the relevant information submitted will be treated in strict enterprise shall be punished in accordance with the regulations on the use of information systems and related inspection and supervision work and improve the information system, and can better reflect all related enterprise production and management of medicine of precursor chemicals.

Since June, agricultural into chloride market movements, the general price shock slump in May is 10-30 yuan (tons price, similarly hereinafter), small drop in the high extent of 50 yuan. Present quotations, wet ammonium mostly factory for 450-52 yuan, dry ammonium mostly for 550-600 yuan, Wholesale market, wet ammonium mostly for 480 - $560, mostly for 6 ~ ($650. Hind, agricultural ammoniacal chloride market faced two big pressure, the market could further weakening.

Hand market demand. In China, most of agricultural ammoniacal chloride used to produce compound fertilizer. Current domestic market is still light compound, offer to drop, high-end products, offer parts cut a pricing relatively low price and small factory recently. At present domestic 45% of chlorine content, mostly for factory offers compound 1800-1850 yuan, 45% s-based compound content is mostly factory offers 2000-2050 yuan, while the actual product factory, the two extreme low chlorine base has come out around $17.5 s-based 1850-1900 yuan, may cut, 50-100 dollars. Compound fertilizer production situation without obvious difference, start at about 50% of the factory maintenance and conditions, and with the start of the summer corn according to demand situation gradually turned pale, and partial enterprise production and maintenance to fall after the start of wheat fertilizer supply again, hind the compound fertilizer production recovery of enterprises may further reduce starts. Fertilizer market for agricultural ammoniacal chloride in recession, the demand.

On the other hand the market supply increases. Most of our agricultural ammoniacal chloride by united, 1 ton production exists about 1 ton soda production chloride. In recent years, along with the increase of soda production in China, China’s rapid increase in productivity and chloride. According to statistics, 2009 in productivity is 1200 tons, chloride copolymer fertilizer production in China in 2005, the proportion of 4% by increased 6% of 2009. By 2010, will have to put the capacity of 1.7million tons, productivity will increase to chloride 1400 tons, a record. Preliminary is expected to yield to chloride by 2010, nearly 1,000 tons of five years, nearly 400 tons chloride yield increase.

Overall, the rapid increase of agricultural ammoniacal chloride market, but recent production demand, supply pressure increased significantly lighter, recent market is likely to continue.

Week of methanol to range trade market. Among them, east area of south reverting to mild signs, no change in the rest declines, weak consolidation situation. Keep Although may reduce methanol quantity import a month, but in general stock market is still high, and downstream demand, lack of effective supply pressure is increased. At first, hind the anti-dumping, June cutting time arrival to import methanol fluctuated because of downstream products, but is not high, the market supply improvement is sufficient, restrict the methanol prices uplink space, methanol market will also in shakeouts.

In east China, the price of methanol market environment of slightly. The market transaction atmosphere is gentle, your mindset gradually stabilised, but still no amplification volume, the grocers though slow, have certain shipment by buying price, but the desire of restriction, price fluctuations. Last weekend in east China market quotation 2050-2100 mainstream (tons, similarly hereinafter).

South China market, the price of methanol atmosphere weakness fall modestly. The market situation is very weak, low downstream demand, buyers to purchase intention is not high, and the recent import methanol concentration to port, the market supply pressure increases, traders, having faith further price declines. Last weekend in mainstream market quotation 2040-2060 yuan, clinch a deal mainly in low, a few to 2,000 yuan.

Huazhong area. Low methanol market, Part of methanol device shutdown, manufacturers inventory maintenance to ease pressure and relatively stable prices, the mainstream in 1970-2050 yuan factory.

In north China market trends, methanol, manufacturers, prices lower delivery intention, the mainstream ex-works small-scope fluctuation in 1800-2030 yuan.

Northeast market price of light, methanol sideways. Due to increased demand, can effective delivery, but slow methanol manufacturer, so the price range inventory commonly. Currently, the coal enterprise in methanol 1800-1900 yuan, gas methanol device, manufacturers selling slow start full, prices continue to hold steady, the mainstream in 2000-2050 yuan quotation, methanol in liaoning province to keep the cash offer in 2080 ~ 21 yuan.

According to physicist organization network on June 9 (Beijing time) reported that the U.S. Virginia Polytechnic Institute and State University, researchers such as by controlling the waste wood and biomass in the volatile components, developed a stable bio-synthetic crude oil (biosyncrude ), so that timber traffic directly into Bio-fuel possible.
The study’s leader, Virginia Tech associate professor of agriculture and life sciences Foster? Abbey China said that in the aspen and pine wood and other raw materials into a liquid fuel, first get the basic bio-oil, because of this foundation unstable and acidic bio-oil, the traditional processing techniques can not be directly converted into transportation fuel. Not only that, the storage period, this basic bio-oil will become more and more dense, until it becomes converted to charcoal to heat another substance. So the basis of bio-oil storage in just a few months later, no longer suitable for use as a bio-fuel substances.
The researchers studied a biomass volatile components: cellulose, hemicellulose and lignin, and control was carried out separately, finally received the biosynthesis of stable crude oil. In addition, they also developed a new catalyst, making the biosynthesis of crude oil even if the store more than 1 year will not become more viscous. Abbey China said that this was the first scientist to produce a stable crude oil biosynthesis.
Abbey China, said that bio-oil can be synthesized using conventional oil refinery infrastructure for production. The next step in the direction of research is to save R & D complex in the middle of the process, so that wood biomass directly into a bio-fuel, used for transportation fuel. Abbey China believes that three years, people can use the existing refinery to produce a large number of stable, affordable biofuel. Then, at the end of refinery inputs of wood, gasoline will come out the other end.
The study was funded by the U.S. Department of Energy, is its beginning in 2008 as part of the biomass program. The plan will biochemistry and thermo-chemical method as biofuels research and development in two ways. The thermal chemical methods are mainly concerned two lines, one after the gasification process and fuel synthesis, another is the processing of liquefied bio-oil and fuel synthesis.
