摘要：
The present invention provides a process for the preparation of a polyether polyol, said process comprising polymerising one or more alkylene oxides in the presence of a multimetal cyanide complex catalyst and an initiator compound, wherein the process is carried out in a reactor vessel equipped with means for agitating its contents and the one or more alkylene oxides are supplied to an agitated mixture comprising the multimetal cyanide complex catalyst and the initiator via a feed inlet device, said feed inlet device comprising a sparger. The present invention also provides a reactor system for the preparation of polyols.
