tert-Butylhydroquinone Chemical Properties,Usage,Production

Chemical Properties
tan powder
Definition
ChEBI: A member of the class of hydroquinones in which one of the ring hydrogens of hydroquinone is replaced by a tert-butyl group.
General Description
White to light tan crystalline powder or a fine beige powder. Very slight aromatic odor.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Phenols, such as tert-Butylhydroquinone, 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 Ka = 1.3 x 10^[-10]). 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. Nitrated phenols often explode when heated. Many of them form metal salts that tend toward detonation by rather mild shock. tert-Butylhydroquinone is incompatible with oxidizers.
Fire Hazard
tert-Butylhydroquinone is combustible.
