摘　　要：利用醋酸和烧碱为主要原料,经反应后得醋酸钠水溶液,加热浓缩后冷却结晶,离心脱水得粗品,用水重结晶后,采用3种不同的洗涤方案用于生产无水醋酸钠,其中以水作为洗涤液最为经济,也最为环保,而采用乙醇和体积比为1︰1的乙醇/异丙醇洗涤时,脱水效果相对较好,晶形也较为完整和均匀。Anhydrous sodium acetate was produced by using acetic acid and caustic soda as main raw materials.The rough product was obtained by concentration,cooling and centrifugation of the mixture reaction solution.Three different washing agents were applied to produce anhydrous sodium acetate.Among the three agents,water was the most economic and eco-friendly washing agent.However,complete and uniform crystal form was produced by using ethanol or ethanol/isopropanol（1︰1）as washing agent.
