摘要
为了优化二甲基砜生产除盐工艺,采用动态变温合成法测定了二甲基砜在甲醇、乙醇、丙酮、纯水中的溶解度参数,并用理想溶液经验方程和Apelblat理论模型对溶解度数据进行了关联.方程计算值与实验值相对偏差较小,拟合结果表明溶解度实验值与理论模型具有较好的关联度.实验测定的二甲基砜在不同溶剂体系中的溶解度数据为研究二甲基砜重结晶热力学研究提供基础参数,对二甲基砜纯化生产实践具有一定的指导意义.
To optimize desalting process in producing methyl sulfonyl methane,the solubility of methyl sulfonyl methane in methanol,ethanol,acetone and pure water was mensurated through dynamic temperature synthetic method and associated with equation of state of ideal solution and Apelblat Model.For calculated value and experimental data are in a small deviation,the fitted result is satisfactory.The solubility data of methyl sulfonyl methane in different solvent systems provides the basic data for the research of thermodynamics concerned with recrystallization of methyl sulfonyl methane,and is effective in production practice of purifying methyl sulfonyl methane.
