摘要
以三氯氧磷和环氧丙烷为原料,先合成磷酸三(2-氯丙基)酯(TCPP),再在碱性催化剂作用下,进行双分子缩聚,合成一种新型高效阻燃剂四(2-氯丙基)-1-甲基-1,2-亚乙基双磷酸酯。对TCPP的缩合反应的机理及条件进行了探讨。结果表明,当反应温度为180℃,反应时间为7.0 h,催化剂用量1.2%时,产物收率可达90.6%。
1-Methyl-l,2-ethylene bis[di（2-chloropropyl） phosphate], a new kind tardant, was synthesized by bimolecular condensation of tris（2-chloropropyl） p sing an alkaline catalyst, raw materials. When the of the struct catalyst was ure was chara 1.2% ctertze which was synthesized by phosphorus oxychloride reaction temperature was 180 ℃, the reaction time of the reactants, the yield of the product was abou d using ESI-MS, IR and 1H NMR. The reaction m of the condensation reaction were discussed. an wa t9 of efficient flame re- hosphate （TCPP） u- d propylene oxide as s 7.0 h and the mass 0.6%. The chemical echanism and conditions
