利用一套激光动态监视、升温速率可控的溶解度测量系统装置，测定了常压下温度范围为277.15~334.15 K内 DL-酒石酸在6种纯溶剂中的溶解度数据，并用Apelblat方程、λh方程和NRTL方程对实验数据进行了关联。结果发现对于纯溶剂体系，DL-酒石酸溶解度的计算值与实验测定值吻合良好；选用的3种方程在所研究的温度和浓度范围内是适用的，可以为DL-酒石酸的结晶分离过程提供数据支持。
Abstract
The solubilities of DL-tartaric in water, methanol, ethanol, N-methylpyrrolidone (NMP), N,Ndimethylformamide (DMF) and N,N-dimethylacetamide (DMAC) have been measured using a laser monitoring technique in the temperature range from 277.15 to 334.15K. The experimental results have been correlated with different equations. For the six pure solvents selected, the data fit quite well with the modified Apelblat equation, the λh equation and the NRTL equation.
