摘要
采用折光率法测定了三氯蔗糖m(醇)∶m(水)=1∶1、m(乙醇)∶m(水)=1∶3、m(乙醇)∶m(水)=3∶1、m(乙醇)∶m(乙酸乙酯)=1∶1、m(异丙醇)∶m(水)=1∶1这5种混合溶剂中的溶解度。通过经验模型和Apelblat方程对所测实验数据进行了关联,取得了较好的关联效果,平均相对误差小于7.5%,且经验模型优于Apelblat方程。实验得到的溶解度数据和关联结果对三氯蔗糖结晶工艺的研究具有较大的指导意义。
The solubilities of sucralose in m (ethanol)∶m (water)=1∶1,m (ethanol)∶m (water)=1∶3, m(ethanol)∶m(water)=3∶1,m(ethanol)∶m(ethyl acetate)=1∶1,m(isopropanol)∶m(water)=1∶1 were determined respectively by the refractive method.The data were well correlated respectively with the empirical model and the Apelblat equation,with the mean relative errors less than 7.5%.It shows that the empirical model is more suitable than the Apelblat equation.The experimental results and correlations obtained are useful to the industrial crystallization process of sucralose.
