Abstract
The present disclosure relates to a process for the production of a base complex catalyst comprising reacting a hydroxide base with a polyalcohol, under vacuum pressure, at a temperature in the range of about 60° C. to about 220° C., wherein the mole ratio of the hydroxide base to the polyalcohol is greater than about 2:1.
Claims21
A process for the production of a base complex comprising
- (i) continuously feeding an aqueous solution of a hydroxide base and a polyalcohol into a reactor equipped with an agitator and a miller, the reactor being fluidly connected to a vacuum and one or more condensers for removal of water;
- (ii) heating the reactor under vacuum pressure at a temperature of about 60° C. to about 220° C. with continuous removal of water, agitating and milling to produce a base complex;
- and
- (iii) continuously removing the base complex from the reactor,
- wherein the mole ratio of the hydroxide base to the polyalcohol is about 2:1 to about 10:1.
A process for the production of a base complex comprising reacting an hydroxide base with a polyalcohol in the presence of water and a reducing agent under vacuum pressure at a temperature of about 60° C. to about 220° C. wherein the mole ratio of the hydroxide base to the polyalcohol is about 2:1 to about 10:1.
