详细介绍了新型磷腈盐(PZN)催化剂的结构、制备工艺及其用于合成聚醚多元醇(PPG)的情况,该类催化剂的脱除与回收方法,新型氧化磷腈(PZO)催化剂的制备及其用于合成PPG的工艺。通过与传统的KOH催化剂和双金属氰化物(DMC)催化剂进行对比,指出PZN是一类极具发展潜力的PPG合成用新型催化剂。 The structure, preparation and application of the novel phosphazene salt (PZN) catalyst were introduced in detail. The removal and recovery methods of this kind of catalyst, the synthesis of new PZO catalysts Preparation and its process for the synthesis of PPG. By comparing with traditional KOH catalyst and double metal cyanide (DMC) catalyst, PZN is a new type of catalyst for PPG synthesis with great potential.
