Enthalpic pairwise interactions of isomers of 2,4-pentanediol and 2,5-hexanediol in dimethylsulfoxide + water mixtures at 298.15 K

► The values of hxx for S-enantiomer are almost higher than R-enantiomer for each diol. ► The 2,4-pentanediol isomers has lower hxx value than 2,5-hexanediol isomers. ► ITC can differentiate different pairs of optical isomers.
