J. Chem. Eng. Data 2018, 63 (5), pp 1833−1840. DOI: 10.1021/acs.jced.8b00196 n the paper (J. Chem. Eng. Data 2018, 63, 1833−1840),1 The solubility of benzophenone in various pure solvents, including water, ethanol, 1-propanol, isopropyl alcohol, methanol, 1-butanol, iso butyl alcohol, 1-octanol, acetonitrile, acetone, ethyl acetate, and methyl acetate, has been measured at temperatures between 278.15 and 318.15 K by a gravimetric method

under atmospheric pressure. The solubility obtained in the selected pure solvents increases with the increasing temperature. Several thermodynamic models, including the modified Apelblat model, NRTL model, and Wilson model, were applied to correlate the measured solubility. It was found that the correlated results of the three models were in good agreement

with the experimental results. In addition, the dissolution thermodynamic properties of benzophenone in the pure solvents were determined. But recently, we find the assumption (given in the original paper) that “ΔheatG + ΔcoolG can also be considered as zero according to the eqs (15−18)” is not very precise and could cause some errors on the calculated ΔdisG, as the value of ΔfusG can be considered as zero due to the equilibrium of the system. The value of ΔheatG and ΔcoolG should not be ignored. As stated in the original paper, we know that the value of (ΔheatH + ΔcoolH) and (ΔheatS + ΔcoolS) can be considered as zero. Therefore, the sum of ΔheatG, ΔcoolG, and ΔfusG can be calculated as follows:

Δheat H + ΔfusH + Δcool H = ΔfusH Δheat S + ΔfusS + Δcool S = ΔfusS Δcool G + ΔfusG + Δheat G = (Δcool H + ΔfusH + Δheat H ) − T (Δcool S + ΔfusS + Δheat S) = ΔfusH − T ΔfusS
So, ΔdisG = x(ΔheatG + ΔcoolG) + ΔmixG = x(ΔfusH − TΔfusS) + ΔmixG. Thus, the value of ΔdisG presented in Table 4 should be recalculated. The corrected data are given in Table 4.
