摘要
介绍了以醋酸、碳酸钠为原料，水为溶剂，采用一步法合成双乙酸钠的新工艺。经正交试验确定的优化合成条件是：ｎ（醋酸）∶ｎ（碳酸钠）∶ｎ（水）为１∶０．２７∶０．５４，反应温度７０℃，反应时间３ｈ。产物收率为９６．０％，产品质量达到美国食品级指标。
A new method for preparing sodium diacetate by onestep reaction based on acetic acid and sodium carbonate (with water as solvent)is studied.The optimized condition by orthogonal design is determined as follows:acetic acid∶sodium carbonate∶water=1∶0 27∶0 54(molar),the reaction temperature is 70℃,the time is 3 hr,and yield is 96%,quality is up to US standard of food grade.
