WebPhenols, such as GALLIC ACID, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88). Websolubility in organic solvents is a key factor for phenol recovery, studies referring to corresponding prediction data are rather limited. A recent study reported the prediction of gallic acid solubility in methanol, ethanol, water, and ethyl acetate at a temperature range of 298.2 to 333.2 K with the modified Apelblat model.[12]
