本研究采用分析搅拌瓶法，在(278.15~333.15)K的温度范围内，用分析搅拌瓶法测定了赤藓糖醇在甲醇+水、乙醇+水和正丙醇+水中的溶解度。实验结果表明，赤藓糖醇在二元混合物中的溶解度随着温度的升高和水的摩尔分数的增加而增大。这些测量结果与修正的Apelblat方程和Buchwski-Ksiazaczak Lambda h方程有很好的相关性。结果表明，修正的Apelblat方程比Buchwski-Ksiazaczak Lambda h方程能给出更好的关联结果。此外，计算结果与实验溶解度吻合较好。因此，实验数据和模型参数对优化赤藓糖醇的工业提纯工艺具有一定的参考价值。皇冠版权所有(C)2012由爱思唯尔出版。保留所有权利。
In this study the solubility of erythritol in methanol + water, ethanol + water, and 1-propanol + water was experimentally measured over the temperature range of (278.15 to 333.15) K at around 5K intervals by employing an analytical stirred-flask method. Experimental result shows that the solubility of erythritol in the binary mixtures increases with the increase of both temperature and mole fraction of water. Results of these measurements were well correlated with the modified Apelblat equation and the Buchwski-Ksiazaczak lambda h equation. It was found that the modified Apelblat equation could give the better correlation results than the Buchwski-Ksiazaczak lambda h equation. In addition, the calculated results show good agreement with the experimental solubilities. Therefore, the experimental data and model parameters would be useful for optimizing the process of purification of erythritol in industry. Crown Copyright (C) 2012 Published by Elsevier B.V.
