Synthesis Reaction Of Polyether Polyols

Pretreatment of raw materials - typically, the initiator and catalyst are pre mixed to generate metal hydrocarbon oxides, which are then vacuum dehydrated and added to the reactor.
Ring opening polymerization reaction - This reaction is exothermic and the reaction heat must be removed in a timely manner; To prevent oxidation reactions, dry nitrogen gas must be introduced before the reaction.
The post-processing process mainly includes units such as neutralization, adsorption, dehydration, filtration, distillation, etc.
