    ——Remember the first prize of scientific and technological progress project based on the directional ring-opening reaction of alkylene oxide to prepare alcohol ether series high value-added fine chemicals industrialization key technology

      Recently won the first prize of the 2021 China Petroleum and Chemical Industry Federation Science and Technology Progress Award , established a comprehensive utilization technology system for by-product resources, and realized efficient and industrialized production
    .

      Alcohol ether fine chemicals are indispensable and important basic materials in key strategic emerging industries such as electronic information chemicals and new energy wind power blades
    .
    In view of the problems such as poor ring-opening reaction selectivity, low batch production efficiency, large by-product pollution, and long-term dependence on imports of high-end products in the production process of such products in China, this project broke through the preparation technology of high-activity and high-selectivity catalysts and developed alcohol ethers Continuous production technology for similar products

    .

      The project has the following four innovations: First, the creation of perchlorate and immobilized SnCl₄ 5H₂O catalysts, benzothiazole ionic liquids, polyglycol diethers and lanthanum-nickel composites and other types of derivatization catalysts have achieved The directional ring opening of the β-position of alkylene oxide solves the problem of catalyst recycling; the second is to develop turbulent tubular and microchannel heat and mass transfer processes to strengthen the ring-opening reaction, pre-reaction-fixed bed two-stage continuous esterification, fixed bed Continuous hydroamination reaction technology breaks through the bottleneck of continuous reaction technology and realizes high-efficiency production; the third is to develop alcohol ether raffinate to prepare polyethylene glycol double ether phase transfer catalyst, and to recover organic matter in by-product brine to prepare epoxy toughened polyester The fourth is to break through the technical bottleneck of high-quality ppb-level metal ion content and low-chlorine content electronic information chemicals, and develop high-quality alcohol ether solvents and aliphatic glycidyl ether active diluents.
    , polyetheramine curing agent, three types of alcohol ether fine chemicals, to achieve industrial production

    .

      The project was completed by Nanjing Forestry University, Changzhou University, Jiangsu Yida Chemical Co.
    , Ltd.
    , Anhui Xinyuan Technology Co.
    , Ltd.
    , Yangzhou Chenhua New Materials Co.
    , Ltd.
    and other units.
    It has obtained 43 national invention patents and led the development of industry 8 standards; 17 sets of 10,000-ton continuous production units have been built, and the production technology has reached the international advanced level

    .

      In addition, more than 20 products such as allyl glycidyl ether produced by this technology filled the domestic gap, and won 9 national key new products and 27 provincial high-tech products; the accumulated sales revenue in the past three years was 4.
    223 billion yuan, and new Profits and taxes were 647 million yuan
