ASSOCIATIONS OF BENZOIC-ACID - II - HYDRA TION INVESTIGATION OF BENZOIC-ACID IN WET BENZENE SOLUTION AT 25-DEGREES-C

The hydration of benzoic acid in wet benzene solution is studied from our first results of partition investigation in two-phase system water -benzene [1] and solubility measurement of water in benzenic phase. Ba sing on correlation found between water and acid in benzenic phase, we show that the monomer-dimer-timer model is quite consistent with the hypothesis of the non constant non-H bonded water contents and monohyd rate formation of monomer and dimer. The hydration constant of monomer is determined; The partition coefficient of monomer, dimerization and trimerization constants are corrected.
