Experimental Properties:Formerly reported as decomp at 235-240 °C|WHITE TO PALE FAWN COLORED CRYSTALS; ODORLESS /MONOHYDRATE/|Solutions of gallic acid, particularly of the alkali metal salts, absorb oxygen and turn brown in air
Air and Water Reactions:Sparingly water soluble (NTP, 1992)
Reactive Group:Acids, Carboxylic
Reactivity Profile:Phenols, 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). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid.
