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.
, Anhui Xinyuan Technology Co.
, Yangzhou Chenhua New Materials Co.
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
