摘要
为发展硝酸酯聚醚黏结剂,以3-羟甲基-3-甲基氧杂环丁烷(HMM O)为底物,N2O5为硝化剂,制备了一种含能单体3-硝酸酯甲基-3-甲基氧杂环丁烷(N IMM O)。讨论了N2O5与HMM O的摩尔比及反应温度对选择性硝化的影响。确定了最佳反应条件:N2O5与HMM O的摩尔比为(1.0~1.1)∶1.0,温度为-15^-10℃,滴加完毕后待温度下降时立即中和终止反应。通过红外、核磁及元素分析对产品进行结构表征,表明是目标化合物,差热分析表明N IMM O的热稳定性较好。
In order to develop nitratopolyether binders, an energetic monomer, 3-nitatomethyl-3-methyloxetane （NIMMO） was synthesized with 3 hydroxymethyl-3-methyloxetane （HMMO）as primary substance and nitrogen peroxide as nitrating agent. The effect of reaction temperature and N2O5/HMMO molar ratio on selective nitration was discussed. The optimum reaction conditions are as follows：n（N2O5）：n（HMMO）= （1. 1-1.0） t 1.0,reaction temperature -15 --10℃ and the reaction was quenched after addition was over when temperature began to descend. The structure of the product was characterized by IR, NMR and elemental analyses, showing that final product was target compound. DSC experiment shows that NIMMO has better thermal stability.
