hc chemical network news “we are a has been sold for 40,000 yuan / ton, and our products from 11 c to 18 c have, as the highest quality of aggregated standards, foreign customers have orders, products in short supply. 2 20,000 tons production capacity expansion project by the end of june will soon put into production after the world’s largest production base of long- acids. “biotechnology co., ltd. shandong han lin sales miss liang xiaojuan says an interview. is an important chemical raw material, refers to the carbon chain containing more than 10 carbon atoms, aliphatic dicarboxylic acids. due to the presence of two hydroxyl groups can generate two series of salts, esters, amides, etc., mainly used for spices, engineering plastics, nylon fibers, hot melt adhesives, high-grade lubricants, plasticizers, and liquid crystal so cold synthesis. however, a long time, technology has been monopolized by the developed countries, and its use of the chemical synthesis, production process complicated, explosive, polluting the environment, costly. institute of microbiology, chinese academy of sciences through the efforts of two generations of experts in more than 10 years, invented the use of bio-fermentation production of , by microbial enzymes are intracellular synthesis of alkane dicarboxylic acid. the completion of this process in the cell, with incomparable advantage of chemical synthesis: production process is simple, production under mild conditions, the entire production process is carried out under normal temperature and pressure, high yields, low cost, no pollution, is a true green chemistry technology enables large scale industrial production. institute of microbiology, chinese academy of reporter learned from the s can significantly improve the quality of synthetic materials, more and more widely used in the field. such as dodecanedioic acid, 13 carbon dicarboxylic acid such as made from plastic with tensile strength, wear good performance, but also to improve the performance of various tires, so that the current life of the tire 5 ~ 10 times. good heat resistance, processability and modified nylon engineering plastics can be used to cast plastic precision molding, alternative non-ferrous metal, widely used in machinery, automobile and other industries. its corrosion resistance, insulation, softness can be made of optical fiber jacket, oil pipelines and parachute ropes. use of synthesis, senior nylon powder coating, with density, low water absorption, cold resistance and good surface hardness, elasticity, abrasion resistance, reduce pollution, the use and safety. with the rapid development of automobile industry in the next few years, demand for powder coatings in china will maintain a steady annual growth rate of 6.6% is expected to reach 300,000 tons in 2015, of which nylon powder coatings consumption will reach 3,000 tons. baling petrochemical engineer polyamide center, said song chao told reporters, as the downstream industry, plastics, hot melt adhesives, lubricants, pharmaceuticals and other spices, and the rapid development of the field, directly stimulating the market for market. among them, 11 carbon to carbon-16 dual acid were used in the synthesis of nylon, high lubricants, rust inhibitors, powder coating, high-grade hot melt adhesives, pharmaceuticals (such as in the synthesis of natural musk, central 15 alternative preparation of the ketone kind of expensive proprietary chinese medicines), and the perfume industry. therefore, the market, tapping the potential of space is very broad. the world of the of the annual demand of 5 million to 60 thousand tons, the market often at a price not available in the tight situation between supply and demand is very conspicuous. it is understood that china currently has, including shandong han lin biotechnology co., ltd., shandong, lung, and through bio-chemical technology co., ltd., kaicong race holdings limited, guangzhou tong chemical co., ltd., qingjiang petrochemical company, shandong lung and through bio-chemical technology co., ltd., etc., many parents acid production enterprises, total capacity has reached 80,000 tons, mainly distributed in shandong, jiangsu and other provinces. one biotechnology co., ltd. shandong han lin is the largest one manufacturer, the company invested nearly one billion yuan in 2008, with research and development of the institute of microbiology, chinese academy of national science and technology progress award were process for technical support, a 10,000 t works in 2009 put into operation in shandong laiyang, two 20 thousand tons will be put into operation by the end of june this year. the company plans a total investment of 3 billion yuan to build an annual output of 60,000 tons of long acid production scale, all completed the company will become the world’s largest production base of long-chain fatty acids. currently, the project has been included in the national development and reform high-tech industrialization demonstration project.
