4-tert-Butylphenol Chemical Properties,Uses,Production

Chemical Properties

white crystalline powder


ChEBI: A member of the class of phenols that is phenol substituted with a tert-butyl group at position 4..

General Description

Crystals or practically white flakes. Has a disinfectant-like odor. May float or sink in water. Insoluble in water.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Phenols, such as 4-tert-Butylphenol, 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.

Fire Hazard


Contact allergens

Para-tert-butylphenol is used with formaldehyde to produce the polycondensate p-tert-butylphenol-formaldehyde resins (PTBPFR). Major occupational sources are neoprene glues and adhesives in industry, in the shoemaking and leather industries or in car production. It is also used as a box preservative in box and furniture manufacture and in the production of casting molds, car brake linings, insulated electrical cables, adhesives, printing inks, and paper laminates. Para-tertbutylphenol seems to be the sensitizer

Purification Methods

Crystallise the phenol to constant melting point from pet ether (b 60-80o). It sublimes in vacuo. Also purify it via the benzoate, as for phenol. The salicylate ester [87-18-30] has m 63-64o (from aqueous EtOH, or EtOH). [Beilstein 6 IV 3296.]
