摘　　要：配制了不同含酸质量浓度的三醋酸甘油酯(TA)溶液作为待洗涤的含酸硝酸酯替代物,开展了微通道反应器洗涤脱酸模拟试验,研究了不同实验因素条件对脱酸效果的影响规律。结果表明:该微反应器条件(通道直径0.5 mm,长度30 mm)下,最大能处理w TA=91%,w H_(2)SO_(4)∶w H_(2)O=2∶3的含酸TA,对应的最佳工艺参数为碱液质量浓度w_(Na_(2)CO_(3))=3.8%,洗液比V_(代料)∶V_(洗液)=100 mL/min∶95 mL/min。结果可为硝酸酯的微反应洗涤脱酸提供参考。Glycerol triacetate(TA)solution with different acid concentration was prepared as a substitute for acid nitrate.Then,the simulation experimental of washing acid TA with microreactor was carried out,the effects of different factors were studied.The results show that,with the condition of the microreactor(the channel diameter is 0.5mm and the length is 30mm),the maximum capacity can be processed is w TA=91%,w H_(2)SO_(4)∶w H_(2)O=2∶3 the best process conditions are w Na_(2)CO_(3)=3.8%,V_(代料)∶V_(洗液)=100 mL/min∶95 mL/min.
