摘要:1-氧基磷杂-4-羟甲基-2,6,7-三氧杂双环[2.2.2]辛烷(PEPA)与三甲基氯硅烷反应合成阻燃成炭剂笼状1-氧基磷杂-4-三甲基硅氧甲基-2,6,7-三氧杂双环[2.2.2]辛烷酯(PTSPA)。探讨了不同溶剂、反应温度和反应物配比对产物产率的影响,最佳反应条件是以二氧六环为溶剂,三乙胺为缚酸剂,PEPA与三甲基氯硅烷的物质的量比为1∶1.15,95℃反应8h,产率为91.6%。通过FT IR、1 H NMR、元素分析、极限氧指数及差热分析等技术表征了产物的结构及性能。实验表明,目标产物有较好的阻燃成炭性和热稳定性。
Antiflaming charring agent caged 1-oxyphospha-4-trimethylsiloxy-2,6,7-thioxabicyclo [2.2.2]- octane ester (PTSPA) was synthesized from 1-oxy phospha-4-(hydroxymethyl)-2, 6, 7-trioxabicyclo [-2.2.2] octane (PEPA) and trimethylchlorosilane. The effects of different solvent, reaction temperature and ratio of raw materials on product yield were studied. The optimal conditions were obtained as follows: The mole ratio of PEPA and trimethylchlorosilane 1 : 1.15, dioxane as solvent,triethylamine as the bind- ing acid agent,reaction time of 8 h and reaction temperature at 95℃. The yield was 91.6% . The structure and properties of the flame retardant products were characterized by using FT IR, 1H NMR, elemental a- nalysis, limiting oxygen index and TG-DTA analysis techniques. The product showed good charring property and thermal stability.
