| Abstract: | A system that acetic anhydride is used as esterification reagent, p - toluenesulfonic acid is used as catalyst, and butyl acetate is used as solvent is described in this paper. Based on this system, a rapid and simple analytical method for the determination of the content of hydroxyl group of polyether is developed. This method finds its valuable application in the production and use of polyether. |
