Cooperation between CAS and Local Authorities

Gap Filling: Industrialized Production of Polycarbonate

After four years’ hard work, the Changchun Institute of Applied Chemistry, CAS in joint efforts with Yinguangjuyin Chemical Corp., Gansu Province successfully developed a new technology for industrialized production of 500 tons of polycarbonate with home-grown intellectual property right. This achievement filled up the gap in the production technology for polycarbonate with one-step phosgene interface method. It also laid an important technological foundation for the development of production technology for 10,000 ton polycarbonate and acceleration of large-scale production in the future.

Ethylene Glycol Production from Coal

The Fujian Institute of Research on the Structure of Matter, CAS, successfully developed a complete set of technologies for “the 10,000 ton synthesis of oxalic ester under the catalysis of CO gas phase and synthesis of ethylene glycol under the catalytic hydrogenation of oxalic ester” (production of ethylene glycol from coal). On Mar. 18, the complete set of technologies passed the check and acceptance by relevant authority. The achievement marked that China has mastered the key technology and realized the industrial application of “production of ethylene glycol from coal”.

New Catalyst for Production of Ethylene Propylene Rubber

After three years’ hard work, the Changchun Institute of Applied Chemistry, CAS in joint hands with PetroChina Jilin Petrochemical Co. successfully developed a new vanadium ethylene propylene catalyst, which is easy to prepare, low in cost and convenient to put into mass production. Since January 2006, these two units have been jointly engaging in the research on “the industrialization development of new vanadium ethylene propylene catalyst”. Their hard work resulted in the new synthesis technology of new vanadium catalyst in aqueous medium. The new catalyst synthesized is easy to prepare in large scale, and thus it can avoid the disadvantages of high corrosion and high pollution during the preparation of VOCl3 catalyst through high temperature colorization. It is insensitive to air and moisture, so it does not have the disadvantages of reduction of catalytic performance and high costs for the storage and transport of VOCl3 catalyst, as such catalyst is easy to be hydrolyzed. It has provided favorable conditions for the development of new brand of ethylene propylene rubber and new olefin copolymer.
