| Abstract: | In this paper, the ether bonds in the polyoxyethylene polyoxypropylene are cracked by the solution of acetylptoluene sulfonic acid . The proporation of AcOCH 2CH 2OAc and AcOCH 2CH(CH 3)OAc is determined by GC, so that the proportion of the epoxyethane and the epoxy propylane is calculated. The best condition is choosed by experiment. The results are satisfactory. |
