Fine chemical is a deep processing industry of petroleum and chemicals.
It not only needs intensive technology, intensive capital, but also the human resources, technology, capital, market of downstream supporting product and many other conditions. It is becoming an important symbol of petrochemical industry development. As the profit margins of petrochemical and basic chemical shrinks, more and more developed countries and large petrochemical companies shift the core industry to fine chemicals. They intend to occupy the next high ground by the leading biotechnology, new materials and new energy technologies.
At present, the output value of China's fine chemical rate of 45% or so, there is a big gap with foreign, mainly in the mostly low-end 10-hydroxydecanoic acid products; refinement of low added value; low level of production technology; enterprises are small, low concentration resource allocation efficiency is not high; environmental pollution has become an important constraint.
China fine chemical industry's main task is to technological innovation to the green, high performance, dedicated and high added value as the objective to address the catalytic technology, process intensification technology, fine processing technology, bio-chemical technology constraints such as China Fine Chemical Industry common key technology industry as a breakthrough, Pesticide vigorously develop new technologies, recycled paper fiber preparation technology specialty chemicals, functional silicone rubber industry technology, fluorine-containing fine chemicals, production technology, to promote the development of relevant industries.
Among them, the dye industry will focus on the development of sulfonation, nitration, reduction, alkali fusion reactions of the four major clean production technologies, improve the level of clean production, the development of high value-added and specialty varieties of functional dyes; paint industry focus on developing water-based, high solids , powdered, and buildings, bridges, aviation, automotive, marine and other areas of high performance products to improve the environmental friendliness of products and dedicated; adhesive industry focuses on the development of modified type, water-based, hot melt type, light-cured , high-solids adhesive products such as preparation of new technologies. Focus on developing high-purity electronic chemicals, reagents, high purity gases, performance materials, preparation of new packaging technologies; paper focuses on the development of waste paper deinking chemical agents, chemical pulp bleaching products, new sizing agent, wet and dry paper reinforcing agent, to meet the development needs of paper industry; bio-chemical non-food renewable resources as raw materials and bio-polymer materials, high value-added products such as the development goals, focusing on development of efficient bio-catalysis, bio-separation coupling reactions, bioreactor technology, development of bio-refining technology, clean production and the end of treatment.
In recent years, China's scientific and technological innovation in the field of fine chemical breakthrough, a series of sophisticated technology should be promoted. For example, to obtain eight alternative patent licensing phosgene, thionyl chloride and other toxic materials, green chemistry technology, eliminating the fine chemicals suppliers from the process safety and environmental risks, technology in the international advanced level, has been achieved in industrial company’s technology, resulting in significant social and economic benefits.
A production of acetochlor fork new process uses a low toxicity for non-aromatic solvent, catalyst and stabilizer in the new conditions, to improve the conversion rate, and eliminate impurities. The color, product content is of 97% while the yield rate reaches to 92%. It avoids the traditional chloromethyl ether route a large number of high salinity, high COD wastewater, and high levels of hydrogen chloride gas generation, avoiding the carcinogenic teratogenic chloromethyl ether production and use, improve resource utilization, more than 97% reduction promote the application of good prospects.
In addition, the application of molecular distillation technology can greatly reduce the separation cost of the high boiling point material and protect the characteristics and quality of thermal material. This technology has been used to produce fish oil, natural vitamin E, linolenic acid, monoglycerides and other complete industrial production. It can also be widely used in petroleum chemical industry, food industry, pharmaceutical industry, perfume industry and so on. Source: http:// www.mhcfm.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
