摘要
为进一步完善柠檬酸钠的制备方法,对影响柠檬酸钠产品质量和产率的一些工艺参数进行了研究和优化。通过一系列实验研究,确定了最佳工艺条件:最适宜的投料时间为20 min、柠檬酸钙投料结束时反应液最适宜的pH值为10.0、浓缩前柠檬酸钠溶液的pH值要调整到6.5-6.7、活性炭最适宜的用量为原料碳酸钠的1/20。同时介绍了柠檬酸钠在各领域的应用。
In order to further improve the preparation method of sodium citrate,some process parameters which affected product quality and yield were studied and optimized.Through a series of experimental studies the optimum conditions were determined in the end： the optimum feeding time was 20min,the optimum reaction solution pH value was 10.0 at the end of feeding calcium citrate,the optimum pH value was 6.5-6.7 before the sodium citrate solution was concentrated,and the optimum ratio of active carbon to sodium carbonate was 1 / 20.Applications of sodium citrate in various fields were introduced in the mean time.
