摘 要:采用5,5-二甲基-2-氯-2-氧-1,3,2-二氧磷杂环己烷和取代苯胺及脂肪二元胺反应,合成了10个未见文献报导的目标化合物 a~ j.通过元素分析、IR、1HNMR、和MS对其结构进行了表征.部分化合物的热重和差热分析表明,化合物最高失重速率的温区在220~400℃,这与大部分高分子材料的热氧降解温区重叠,具有很好的阻燃配伍性能.在醇酸清漆和环氧树脂中的初步阻燃测试表现出很好的阻燃性能.Compound Ⅰ_a~Ⅰ_j were synthesized from 5,5-dimethyl-2-chloro-2-oxo-1,3,2-dioxaphosphosrinane and various amines. The structures of the compounds were confirmed by IR,()~1 H NMR,MS and elementary analysis. TG and DTA analysis of some of the compounds were discussed. Most of the compounds began to decompose at 220℃ and had certain thermal stability. They decomposed rapidly during 220~400℃ which overlapped with many polymeric material decomposition temperature range. Prelimary test in alkyl resin vernish and epoxy E-44 showed that the compounds had high activity of flame retardance.
