| Abstract: | 4,4'-Oxylbisbenzenesulfonyl hydrazide is a kind of blowing agents.It is widely used in rubble and plastics industry.This compound was prepared by the reaction of diphenyl ether and sulfuric acid,then followed by treatment with phosphorus oxychloride (POCl_3). 4,4'-Oxylbisbenzenesulfonyl chloride,intermediate,then reacted with NH_3·H_2O and NH_2NH_2·H_2O at 30～40℃ for 3 hours.The conditions of synthesis were seriously investigated in this paper. |
