| Abstract: | An intumescent flame retardant aluminum salt of 2-acyl ethyl(phenyl) phosphinic acyl hydrazine was synthesized from 2-carboxyl ethyl(phenyl) phosphinic acid and hydrazine.The optimal synthesis conditions were as follows: the molar ratio of 2-carboxyl ethyl(phenyl) phosphinic acid to hydrazine was 1∶1,the reaction was carried out under reflux(140℃) for 6 h in xylene,then aluminum sulfate was added into the solution.The yield was 93.1%.The structure of obtained product was characterized by IR,NMR,EA(CHONS) and DSC.The flame retardance was tested in polybutylene terephalate(PBT). |
