| Abstract: | In this paper, the ether bonds in the pdyoxyethylene polyoxy propyene are cracked by the solution of ethcnoyl-opposite methylbenzene suphonicacid.The proportion of ACOCH2CH2OAC and ACOCH2CH2OAC is determined by GC, So the proportion of the epexyethane and the epoxy propylana is calculated.The best condition is choosed by experiment. The results are satisfactory. |
