China Drying Network Dawn Chemicals Research and Design Institute Co., Ltd. released information last weekend that the hospital successfully produced high activity and low degree of unsaturation polyether polyol (polyether referred to) and sold to domestic users. Wang Wenhao, director of Polyether R&D Department of Limingyuan, said that the 20,000 tons/year plant with continuous synthesis of polyether polyol technology runs smoothly, and the process technology and product indicators have reached the world's advanced level.
The process technology for the continuous synthesis of polyether polyols developed by Liming Institute of Technology uses a small molecule polyol as a starter, which has high production efficiency, safe and stable process, low pollution, low energy consumption, high product quality, and good stability. The traditional KOH process technology, DMC based batch process technology and the defects in product quality of polyether production are avoided.
