Our institute has been engaged in natural gas chemistry research for more than 40 years since 1958.
The field of fine chemical industry is another scientific and technological development direction of our institute. Now we mainly research, develop, produce and operate "Changkongpai" fine chemical products with 22 series and more than 70 varieties and specifications.
It has taken the lead in developing and completing more than 40 scientific and technological achievements in China, such as making acetylene from natural gas, making carbon tetrachloride and chloroform from natural gas, making vinyl acetate from natural gas, polyvinyl alcohol, vinylon and hemostatic fiber, making polyvinyl chloride from natural gas dilute acetylene, desulfurization from natural gas and making synthetic ammonia from natural gas. The self-developed production technology of methyl chloride from natural gas has been popularized to 70% in the whole country; In the 1970s, a large number of technical backbones were sent to support the construction of Sichuan-Victoria. Acetylene production from natural gas partial oxidation rotary flame furnace is a major national scientific research project, which won the major scientific and technological achievement award of the National Science Conference, the first prize of major scientific and technological achievement in Sichuan Province and the national patent. The "Eighth Five-Year Plan" national key science and technology project "Co-production of ethylene by using the waste heat of natural gas acetylene furnace" passed the national technical appraisal and acceptance in June 1995, and won the national patent; The ninth five-year plan scientific and technological key project "Engineering research of natural gas rotary flame acetylene furnace", 200 1 passed the national appraisal; The national key technological innovation project "industrial test of producing propionaldehyde by a three-gas-fired acetylene furnace with one furnace" passed the expert appraisal and acceptance organized by the Municipal Economic Commission on 200 1.
The field of fine chemical industry is another scientific and technological development direction of our institute. In recent years, our institute has undertaken more than ten national and Chongqing key scientific and technological research projects, small-scale industrialization projects and key technological innovation projects. Among them, aluminate coupling agent series and calcium propionate, a new food and feed additive, were rated as "Chongqing high-tech new products" and "Chongqing key new products"; Propamocarb, an agricultural fungicide, was a key scientific and technological innovation project in Chongqing in 2002. Thione is a new type of high-efficiency and non-toxic penetration enhancer, which is mainly used in medicine, pesticide, cosmetics and other industries and is an auxiliary agent to promote drug transdermal absorption. Cationic cellulose and cationic guar gum are hair softeners and antistatic conditioners. 123 1-cl is a quaternary ammonium salt cationic surfactant; In 2000, the national key new product trial plan "ethylene glycol monoallyl ether" is a kind of active diluent with excellent performance.
