摘要
通过改变投料配比 ,改进结晶 ,提纯干燥等工艺过程。产品的收率由原来的 70 %提高到 90 %以上 ,生产周期缩短近半。产品的含量高达 99 5 %
By varying the ratio of composition and improving on the process of crystallization?purification and drying,the yield can increase from 70% to over 90%,the period of production decrease by one-half and the purity of product is more than 99 5%.
