Realize the continuous production of alcohol ether products

——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

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.

The project was completed by Nanjing Forestry University, Changzhou University, Jiangsu Yida Chemical Co.

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.
