摘要
对八角茴香油 ( anise oil)在三种溶剂中的结晶分离过程进行了研究 ,考察添加剂对结晶析出的影响 ,并用溶解度参数理论阐明溶剂的性质与结晶的关系。结果表明 :乙醇、甲醇的结晶分离性能较为理想 ,而丙酮较差 ;添加剂能显著提高结晶产物的收率 ,但对结晶产物的纯度有一定的负面影响。
Crystallization separation of anise oil in three kind solvents,as well as the influence of additive,was studied.It was concluded that alcohol and methanol had a more better effect than acetone on crystallization separation.Additive can intensely enhance the yield of crystallizing product,but with a certain negative influence on purity.The relation between crystallization and solvents property was described in theory of solubility parameter.
