| 摘 要： | 通过研究一锅法合成DPT工艺为DPT法制备HMX工艺改进提供依据.以尿素为起始原料,中间体不分离,经硝化、水解、Mannich缩合等反应得到DPT.考察硝酸用量、硝化时间、水解时间、甲醛用量和介质pH值等因素对DPT收率的影响,确立了较佳工艺.当发烟硝酸用量11.5 mL,硝硫混酸体积比1.1,硝化60 min,水解90 min,体积分数37%~40%的甲醛溶液40.8 mL加热至40℃反应40 min,氨水中和溶液至pH=7.5,DPT产率65.2%.

| Abstract: | Dinitro pentamethylene tetramine(DPT) is an important precursor of octogen(cyclotetramethylene tetramine,HMX).This article explores the process of synthesizing DPT by one-pot method to provide a practical basis for improving HMX production through DPT.The urea was used as the original material.Without isolation from intermediates,DPT was obtained by the chemical reaction of nitration,hydrolysis and Mannich condensation.Some factors to affect yield of DPT were investigated,such as dosage of nitric acid,nitra... |
