The influences of the neutralization reaction conditions of triethylamine hydrochloride,including temperature,time,pH value,etc.,on the yield of triethylamine are explored.After the reaction is completed,the neutralization solution is separated by phase.The solubility of water in triethylamine and the solubility of triethylamine in water are explored at different temperature.The impact of separation residence time on the separation effect is also explored.By means of simulation software,a dual tower distillation is preliminarily designed.According to the simulation conditions,a device is built in the laboratory and good results are achieved.Based on the research results,a process for industrial scale unit is designed.
