本文测定了苯甲酸在水-乙醇混合溶剂中的电离焓, 并就此进行了讨论。

关键词: 乙醇, 苯甲酸, 水, 电离,

The enthalpies of ionization of benzoic acid have been determine microcalorimetrically at 298.15 K in water-ethanol mixtures by measuring directly the heats of neutralization of sodium benzoate with perchloric acid. The ionization enthalpy curves showed min. and max. in the water-rich region.

Key words: ETHANOL, BENZENECARBOXYLIC ACID, WATER, IONIZATION, ENTHALPY
