Abstract

The invention concerns the catalyst using 6-H-Gu-Mn as the framework, and its producing way and application in gathering ether. The catalyst is synthesized by water dissolved Mn salt, 6H-Gu acid (salt), organic match thing, organic functions compound and polymer. The gathering ether made by this way , has the features of fewer high numerator tail, low glue degree, the gathering ether compounded at high temperature has low degree of not saturation, narrow distributing of numerator.

Description

technical field [0001] The invention relates to a cyanide complex catalyst (hereinafter referred to as DMC) and its preparation method and its application in the preparation of polyether polyol. Background technique [0002] The DMC catalyst is usually a cyanide-coordinated double metal complex precipitate. Commonly used double metal cyanide complexes include hexacyanocobalt zinc, hexacyanoferric (2 or 3 valent) zinc, tetracyanide nickel zinc, hexacyanoiridium zinc and cyanide complexes in which zinc is replaced by iron, cobalt, nickel, etc. compound precipitation. When this simple cyanide complex is used as a catalyst, the activity is very low. When other ligands such as some metal halides and organic ligands are added to the DMC catalyst, its catalytic activity is greatly improved. Its preparation process is generally to add organic ligands to the suspension of the newly generated double metal cyanide complex for complexation reaction, and then use the aqueous solution o...
