Abstract Vaporization/sublimation enthalpies for twenty-one disubstituted benzenes were calculated from dissolution enthalpies and solvation enthalpies in four solvents of different polarity: carbon tetrachloride, benzene, N,N-dimethylformamide, and acetonitrile. The values of solvation enthalpy were calculated using group-additivity scheme for each solvent. Dissolution enthalpies of some substances were taken from literature and fifty-six original values were measured in the present work. The calculated values of vaporization/sublimation enthalpy were compared with the literature data. It was concluded that calculated vaporization/sublimation enthalpies do not depend on the choice of solvents excluding those that interact with the solute specifically.

用于测定不同溶剂中蒸发和升华焓的溶液量热法验证：二取代苯的示例

摘要 由四氯化碳、苯、N,N-二甲基甲酰胺和乙腈这四种不同极性溶剂的溶解焓和溶剂化焓计算出21种二取代苯的汽化/升华焓。使用每种溶剂的基团相加方案计算溶剂化焓值。某些物质的溶出焓取自文献，本工作测量了 56 个原始值。蒸发/升华焓的计算值与文献数据进行了比较。得出的结论是，计算出的蒸发/升华焓不取决于溶剂的选择，排除那些与溶质特别相互作用的溶剂。
