[Ten years of major development in chemical technology] 004-2023 Breakthrough in the industrialization of domestically produced m-dipropenylbenzene technology

Thread Content

On February 6, we learned from Jiangsu Evergreen New Materials Technology Co., Ltd. that the company’s independently developed m-dipropenylbenzene localization technology has made a breakthrough in the industrialization, and the device has passed the “three simultaneous” acceptance, marking that my country has once again broken foreign monopoly in the field of fine chemicals. 　　The person in charge of the company told reporters that my country has not yet realized the industrial production of m-dipropenylbenzene, and the relevant market has been monopolized by foreign companies. To this end, Evergreen has successfully realized the industrial production of m-dipropenylbenzene and the raw material m-dicumylbenzene after several years of research and development. The company's 10,000 tons/year dipropenylbenzene plant entered stable mass production in September 2022. The product purity is greater than 98.5%, and the product quality is at the leading international level. 　　Meta-dipropenylbenzene is an important cross-linking agent in the industrial field and has excellent performance in the preparation of high-performance supramolecular polymers. It is mainly used in the preparation of special rubber, modification of various polymer materials, and the synthesis of some water-soluble coating polymer components. 　　The person in charge of the company said that the market demand for water-soluble coating products in my country is currently strong, but some high-end products are monopolized by foreign countries. An important reason is that the country does not master the production technology of the raw material m-dipropenylbenzene and does not have industrialized equipment. The company's 10,000 tons/year dipropenylbenzene plant has been put into operation this time, opening up the "blocking points" and "breaking points" in my country's high-performance specialty molecular polymer industry chain, filling the gap in the domestic high-end cross-linking agent field, and will enhance the research and development level of my country's high-performance specialty polymer polymers and have a profound impact on the new materials industry in many fields. 　　The person in charge of the company said that the company's dipropenylbenzene products have been sent to many domestic and foreign downstream companies for trial samples. In the future, they will provide more stable products for the downstream industry and accelerate the integration of localized innovative technology and the market. The company mainly produces and operates divinylbenzene, * * Ethylene series unsaturated monomers, triphenyl phosphite series polyvinyl chloride additives, drier series coating additives and oil field refinery petroleum additives.
