| 摘 要： | 以甲基丙烯酸-β-羟乙酯(HEMA)与O,O-二乙基硫代磷酰氯为原料,在三乙胺作缚酸剂,氯化亚铜(CuCl)作催化剂的条件下,合成了甲基丙烯酸2-(二乙氧基硫代磷酰氧基)乙基酯(DPTEM)阻燃剂,再与丙烯腈共聚得到了阻燃聚丙烯腈共聚物。在n(HEMA)/n(三乙胺)=1,m(CuCl)/m(HEMA)=0.01~0.02,反应温度0~5℃条件下,DPTEM的产率达82%;通过FTIR、1HNMR、MS测试技术表征了DPTEM的结构,证明产品结构正确。丙烯腈共聚物中w(DPTEM)=25%时,极限氧指数(LOI)值可达27。该工艺已通过中试,正在进行扩大化生产。

| Abstract: | The fire retardant 2-(diethoxyphosphorothioyloxy)ethyl methacrylate(DPTEM) was synthesized in 82% yield by reacting β-hydroxyethyl methacrylate(HEMA) and diethylthiophosphoryl chloride in molar ratio 1∶1 at 0~5 ℃ with triethylamine as acid acceptor(n(triethylamine)/n(HEMA)=1) and CuCl as catalyst(m(CuCl)/m(HEMA)=0.01～0.02).Structure of the title compound was characterized by FTIR,1HNMR and MS.The fire-retardant polyacrylonitrile was obtained by copolymerization of DPTEM with acrylonitrile.The limiting oxygen index(LOI) value can reach 27 when m(DPTEM)/m(copolymer)=25.This synthesis technology has been scaled up. |
