安替比林母液回收综合利用技术研究

Research on Recovery and Comprehensive Utilization Technology of Mother Liquor of Antipyrine

从安替比林原油结晶后的母液中回收安替比林的技术研究,包括浓缩、脱色、降温结晶、重结晶、精制、离心和干燥工序,不仅充分合理利用了结晶后的母液,而且保证了安乃近的质量,方法简单,回收率高,安替比林产品纯度高。

The processes of antipyrine recovery from antipyrine mother liquor after crude oil crystallization includ concentration, decolorization, coohng crystallization, recrystallization, purification, centrifugation and drying.The method could not only make full use of the mother liquor after crystallization, but also ensure the quality of analgin,and was simple, had high recovery rate and high purity of antipyrine product.
