Production method of reactivity poly- ether poly- all which possesses ethylene oxide terminal block

摘要

Topic It can execute easily and at the same time it offers the method of being used for the production of reactivity poly- ether poly- all which possesses the terminal block of ethylene oxide.Solutions Poly- ether poly- all which manufactures beforehand A) making use of the compound metal cyanide chemical material (DMC) catalyst is loaded in the reactor, continuously the H- functionality start substance and propylene oxide are added, the process which manufactures the poly- ether poly- all precusor at the time of semi- continual operating continuously making use of the DMC catalyst, The process which B) process A) from in the reactor which is operated continually, under existing of the DMC catalyst, propylene oxide or ethylene oxide/reacts the poly- ether poly- all precusor, with the propylene oxide blend, obtains the poly- ether poly- all intermediate field, C) the process which is mixed with alkaline metal hydroxide process B) from the intermediate field as a catalyst, The process which D) it reacts with ethylene oxide in the reactor which is operated continually obtains the end product, and The process which is separated from the end product which can E) process D) in the catalyst,Production method of poly- ether poly- all which it possesses. Selective figure It is not
