tert-Butylhydroquinone Usage And Synthesis

Chemical Properties	White, crystalline solid having a characteristic odour. tert-Butylhydroquinone (TBHQ) is an antioxidant used to preserve oils, fats and food items. It is found in vegetable oils and animal fats, varnishes, lacquers, resins, oils field additives, and perfumes.In low concentrations it shows cytoprotective qualities while at higher concentrations it exhibits cytotoxic behavior. TBHQ was used to study the inactivation of barotolerant strains of Listeria monocytogenes and Escherichia coli.Environment friendly electrode materials for supercapacitors were attained by decorating the surface of graphene nanosheets with TBHQ.
Uses	tert-Butylhydroquinone (TBHQ) is an antioxidant that exhibits an excellent stabilizing effect in unsaturated fats and oils. It has good solubility in fats and oils, with a maximum usage level of 0.02% based on the weight of the fat or oil or the fat content of the food product. It shows no discoloration in the presence of iron and produces no discernible flavor or odor. It can be combined with BHA and BHT. It is used in edible fats and vegetable oils to retard rancidity. It is used in potato chips and dry cereal. It is also termed butylhydroquinone and mono-tertiary-butylhydroquinone.
Uses	antioxidant in cosmetic products like lipsticks.
Uses	TBHQ was used to study the inactivation of barotolerant strains of Listeria monocytogenes and Escherichia coli. Environment friendly electrode materials for supercapacitors were attained by decorating the surface of graphene nanosheets with TBHQ. TBHQ is frequently used as a food preservative. Inhibition of oxidative rancidity in frozen cooked fish flakes by tert-butylhydroquinone. Nuclear factor E2-related factor 2-dependent antioxidant response element activation is by tert-butylhydroquinoneoccurring preferentially in Astrocytes conditions.
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.

First aid measures

General advice
