采用芯片式微反应器,进行了硝酸酯类炸药的合成研究.在该反应器中,以醇和硝硫混酸为原料,太根的产率为86.4%;硝化二乙二醇的产率为90.6%.研究了硝化剂与原料比值和液相空速对反应的影响,实验结果表明,酸与醇摩尔比较小时硝酸酯的产率随着液相空速的降低而增大,但硝酸与醇摩尔比增大后,硝酸酯产率变化不大;硝化剂与原料醇的比值有一个最佳值,HNO_3/二乙二醇=5/1,HNO_3/三乙二醇=4/1,当大于或小于这一比例时,硝酸酯的产率都将下降.

Nitrate ester explosives were synthesized in chip based micro reactor. When alcohol and nitric-sulfuric mixed acid are mixed in the micro reactor,the yield of triethylene glycoldinitrate(TEGN) is 86.39%,and the yield of diethylene glycol dinitrate is 90.60%. The effects of the ratio between nitration agent and raw material,and the effect of liquid hourly space velocity(LHSV) on the reaction were studied. The results show that when the ratio of acid/alcohol is low,the yield of nitrate explosives decreases with the increase of LHSV,however,when the mole ratio of acid/alcohol increased for a certain,the yield of the product did not change significantly with the decrease of LHSV. And the optimal mole ratio of nitric acid/alcohol for diethyleneglycol is 5,and for triethylene glycol is 4.
