|Resumo: ||Phenolic compounds are typically found in plants, usually as esters
or glycosides . Apart from being starting materials for many chemical
synthesis, there is also huge evidence that some phenolic compounds have
beneficial effects on human health.
In this work, the aqueous solubilities of some phenolic compounds
such as the hydroxybenzoic acids gallic, salicylic, protocatechuic and
syringic acids, and the phenilpropenoic acids caffeic, cinnamic, ferulic and
coumaric acids are addressed. Measurements were performed, as a function
of temperature, between 288 K and 323 K, at atmospheric pressure, using
constant-temperature jacketed equilibrium glass cells.
Approaches for modelling the measured data were evaluated,
including the modified UNIQUAC model  and the CPA equation of state
