On March 31, news came from PetroChina Dushanzi Petrochemical Company that the narrow-distributed branched rare earth butadiene rubber jointly developed by China National Petroleum Corporation and Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences successfully completed the industrial test and achieved 30,000 tons.
/Year production demonstration
.
Experts organized by the China Petroleum and Chemical Industry Federation conducted an on-site assessment of the industrial test.
Narrow-distributed branched rare earth butadiene rubber is an important research content of the 2017 National Key R&D Program "Key Technologies for High-Performance Synthetic Rubber Industrialization" (2017YFB0307100)
.
The aim is to develop a new method for the controllable coordination polymerization of butadiene catalyzed by rare earths, to develop high-activity, highly-oriented rare-earth catalysts and narrow-distribution, long-chain branched rare-earth butadiene rubber preparation technology, and to produce 30,000 tons of industrial The device realizes production demonstration
After 8 years of continuous research, the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences, PetroChina Dushanzi Petrochemical Company, Petrochemical Research Institute, and Jinzhou Petrochemical technicians have developed a single-active-site rare earth catalyst preparation technology and a reversible chain transfer polymerization process.
After the engineering problem, the industrialization of narrow-distributed branched rare earth butadiene rubber was successfully realized
.
In this industrial trial, Mooney 45 and 60 products were successfully trial-produced
Rare earth butadiene rubber is another 10,000-ton production demonstration completed in the "Key Technologies for High-Performance Synthetic Rubber Industrialization" project after bromobutyl rubber, marking another important step towards the ultimate goal of the project
