The objective of this data article is to show by calorimetric curves and the immersion enthalpies the differences between the interactions that occur when two activated carbons of different textural and chemical properties are put in contact with C compounds (an aromatic and a closed chain aliphatic: benzene and cyclohexane, respectively) in their pure state, and subsequently in mixtures thereof, with different molar composition. The greatest interaction occurs with the activated carbon that has the lower content of oxygen groups on the surface, both for the pure solvents, as for the mixtures; As for wetting liquids, there is a greater interaction with benzene (-∆H: 94.98-106.40 J g) than with cyclohexane (-∆H: 21.23-65.97 J g). The immersion enthalpy values for the different molar fractions are between -36.51 and -79.69 J g for the oxidized sample, and between -50.43 and -85.59 J g for the sample without chemical modification.
本数据文章的目的是通过量热曲线和浸入焓展示，当两种具有不同结构和化学性质的活性炭与纯净状态下的碳化合物（分别为一种芳香族和一种闭链脂肪族化合物：苯和环己烷）接触，随后与不同摩尔组成的它们的混合物接触时，所发生的相互作用之间的差异。对于纯溶剂以及混合物而言，与表面含氧基团含量较低的活性炭发生的相互作用最强；至于润湿液体，与苯（-∆H：94.98 - 106.40 J g）的相互作用比与环己烷（-∆H：21.23 - 65.97 J g）的更强。氧化样品不同摩尔分数下的浸入焓值在-36.51至-79.69 J g之间，未进行化学改性的样品的浸入焓值在-50.43至-85.59 J g之间。
