Abstract
The preparation of polyethers from primary and secondary amino derivatives of carbohydrates and compounds containing at least one 1,2 epoxy group, in the presence of a catalyst is characterized by reacting the epoxide with a solution of the carbohydrate derivative in water to the stage where the reaction products of epoxide and water are still removable by distillation, removing the latter products by distillation and further reacting the reaction product of polyhydric compound and epoxide with more epoxide. Specified amino derivatives of carbohydrates are glucamine, glucosamine and glucosaminol and their N-alkyl and N-aryl derivatives. Particularly suitable 1,2-epoxides are propylene oxide and butylene oxides. Mixtures of epoxides may be used. Suitable temperatures are 50 DEG to 150 DEG C. and pressures of up to 80 p.s.i. may be used. Alkaline catalysts are preferred, e.g. hydroxides, carbonates and amines. The Example described the preparation of an oxypropylated N-methyl glucamine.ALSO:The preparation of polyethers from primary and secondary amino derivatives of carbohydrates and compounds containing at least one 1,2-epoxy group, in the presence of a catalyst, is characterized by reacting the epoxide with a solution of the carbohydrate derivative in water to the stage where the reaction product is liquid at temperatures above 90 DEG C. and the reaction products of epoxide and water are still removable by distillation, removing the latter products together with excess water by distillation and further reacting the reaction product of polyhydric compound and epoxide with more epoxide. Specified amino-derivatives of carbohydrates are glucamine, glucosamine and glucosaminol and their N-alkyl and N-aryl derivatives. Particularly suitable 1,2-epoxides are propylene oxide and butylene oxides. Mixtures of epoxides may be used. Suitable temperatures are 50 DEG to 150 DEG C. and pressures of up to 80 p.s.i. may be used. Alkaline catalysts are preferred, e.g. hydroxides, carbonates and amines. The example describes the preparation of an oxypropylated N-methyl glucamine. The hydroxylended polyethers of the process are highly reactive towards isocyanates and are used to prepare cellular or non-cellular polyurethanes by reacting with polyisocyanates in the presence, as necessary, of other agents such as water and inert liquids of low boiling-point.
