在流动微量热仪上测定了298.15K下碳酸二甲酯或碳酸二乙酯+氧杂环己烷、氧杂环戊烷、1,4-二氧杂环己烷和1,3-二氧杂环戊烷的过量摩尔焓(HmE)。光滑表示的结果。对于所有混合物,HmE值均为正值,最大值范围为25 ~ 550 Jmol-1
Excess molar enthalpies, H m E , of dimethyl carbonate or diethyl carbonate+oxane, oxolane, 1,4-dioxane, and 1,3-dioxolane are measured at 298.15 K in a flow microcalorimeter. Smooth representations of the results are presented. For all mixtures, the H m E values are positive with a maximum ranging from 25 to 550 J mol -1
