The manufacturing technique of polyether polyols was brief introduced. The reason for producing odor in synthesis process was analyzed, and the specific resolvent was proposed.
Compared with other hydrogen extraction processes the double ammonia synthesis process for purge gas treated with liquid ammonia absorption is a simpler process with low operation energy consumption.
The results of lab and pilot experiments show that the synthesis process is very stable and defoaming property of the product is very good.
Reaction mechanism of synthesis process of forsterite refractory with iron ore tailings
Improvement on synthesis process of 1-(4 - pyridinyl)-2-propanone
