一种磷系阻燃剂的合成及表征

摘要

Bismethyl propanediol dithiopyrophosphate ( BMPDTP) flame retardant was synthesized by reacting methylpropanediol with thiophosphoryl chloride as raw material, dimethyl benzene as solvent, pyridine and triethylamine as deacid reagent. Compound BMPDTP was characterized by FTIR,1H NMR and MS. The thermal properties of compound was researched based on DSC and TG curves.%以2-甲基-1,3-丙二醇和三氯硫磷为原料,二甲苯为溶剂,在吡啶和三乙胺的作用下合成了新型阻燃剂P,P'-二硫代焦磷酸双(甲基丙二醇)酯(BMPDTP).利用红外光谱、核磁共振氢谱和质谱对化合物BMPDTP的结构进行表征,并用差示扫描量热分析(DSC)和热失重(TG)对其热性能进行了研究.
