Mixing of N-methylpyrrolidone with monocycloaromatic hydrocarbons takes place with an endothermic effect and mixing with bicycloaromatic hydrocarbons occurs with an exothermic effect. This is due to an increase in the proportion of the specific reaction in going from systems with mono- and bicycloaromatic hydrocarbons from 30 to 50-60% of the total enthalpy of the reaction. The enthalpies of the specific reaction of arenes with N-methylpyrrolidone are correlated with the donor numbers of the hydrocarbons. The difference in the enthalpies of solvation of saturated and aromatic hydrocarbons by N-methylpyrrolidone is greater than with dimethylformamide and furfural, which is in agreement with the higher selectivity of N-methylpyrrolidone.
