Manufacture of pantyl/d-panthenol mixtures.

摘要

A method of producing mixtures of pantyl/d-panthenol mixtures directly is provided by reacting d-pantolactone with a mixture of 3-ethoxy propylamine and propanolamine whereby the d-pantolactone reacts simultaneously with each amine in the same reaction vessel and produces pantyl and d-panthenol in the same weight % ratio as the ratio of gram molecules of 3-ethoxy propylamine to gram molecules of propanolamine.
