DOUBLE METALLIC CYANIDE CATALYSTS THAT CAN BE USED TO PREPARE POLIALCOHOLES AND PROCESSES RELATED TO THEM. |
abstract |
The present invention relates to double metal cyanide ("DMC") catalysts that can be used to prepare polyalcohols. The DMC catalysts of the present invention are prepared by combining i) at least one metal salt; ii) at least one metal cyanide salt; iii) at least one organic ligand that forms complex; iv) at least one alkali metal salt; and, optionally, v) at least one polymer with function. The present invention also relates to a process for preparing a polyol in the presence of a DMC catalyst of the present invention or prepared according to the present invention. Surprisingly, the DMC catalysts of the present invention, which are preferably prepared with at least one alkali metal halide, have acceptable activity and can be used to catalyze oxyalkylacio reactions. Additionally, DMC catalysts produced by the process of the present invention can be used to prepare polyalcohols having reduced levels of high molecular weight glue. |
