Excess molar enthalpies for (acrylonitrile + benzene, or methylbenzene, or 1,2-dimethylbenzene, or 1,3-dimethylbenzene, or 1,4-dimethylbenzene, or 1,3,5-trimethylbenzene, or ethylbenzene) at T = 298.15 K and p = 101325 Pa are presented. The excess molar enthalpy range from 531 J (.) mol(-1) at x = 0.5 for 1,3,5-trimethylbenzene to 210 J (.) mol(-1) at x = 0.5 for toluene. The Redlich-Kister equation, the NRTL and UNI-QUAC models were used to correlate the data.
