摘要
向高压釜中155℃的三氯三硝基苯(TCTNB)的甲苯溶液液面上通入0.25MPa无水氨气,持续搅拌一定时间后合成出粗颗粒TATB(DTATB)。考察反应温度、时间、氨气流量、原材料浓度、搅拌速度对产品颗粒度及质量的影响,结果表明这些因素均以综合效应影响到最终产品。考察原材料纯度对产品质量的影响表明:甲苯和TCTNB纯度不仅影响产品纯度,而且对产物的产率、粒度、物化性质均有不同程度影响。采用分析纯甲苯和较高纯度TCTNB时,产品质量和产率都较好且产品表观颜色浅;在控制TATB粒度和氯含量方面,工业级甲苯仍然可用。实验中优化了实验室合成百克量级DTATB的工艺参数,并采用间歇法合成DTATB,得到了重复性较好的产品。
The coarse TATB was synthesized after continuous stirring a period of time at 155 ℃ when anhydrous-gaseous ammonia with 0.25 MPa was fed on the surface of toluene solution dissolved trichlorotrinitrobenzene(TCTNB) in a high-pressured rector. The influence factors including temperature,time,ammonia flux,TCTNB concentration and stirring rate ect. on TATB particle size and quality were investigated. The results show the factors affect products comprehensively. The toluene and TCTNB affect not only the purity of products but also the productivity,the particle size as well as the physical and chemical properties of TATB. The more pure toluene and TCTNB,the better quality,productivity and the color of TATB was. However,industrial class toluene could also be used to control the particle size and the content of chloride of TATB. The technical parameters of synthezing coarse TATB in lab at 100 g level were optimized.
