4-(2-Butyl)phenol Chemical Properties, Uses, Production

Chemical Properties

The butylphenols include several isomers. Solid butylphenols (28805-86-9) generally have properties similar to the above:

Uses

Phenolic Resins, Epoxy Resins

Definition

ChEBI: 4-sec-Butylphenol is an alkylbenzene.

Safety Profile

Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. Combustible when exposed to heat or flame. When heated to decomposition it emits toxic fumes. To fight fire, use foam, CO2, dry chemical. Incompatible with oxidizing materials. See also PHENOL and other butyl phenols.

Potential Exposure

Butylphenols may be used as intermediates in manufacturing varnish and lacquer resins; as a germicidal agent in detergent disinfectants; as a pour point depressant, in motor-oil additives; de-emulsifier for oil; soap-antioxidant, plasticizer, fumigant, and insecticide

Shipping

UN2430 Alkylphenols, solid, n.o.s. (including C2-C12 homologues), Hazard class: 8; Labels: 8— Corrosive material

Incompatibilities

Vapors may form explosive mixture with air. These phenol/cresol materials can react with oxidizers; reaction may be violent. 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 cause the gas to ignite and explode. Heat is also generated by the acid-base reaction with bases; such heating may initiate polymerization of the organic compound. React with boranes, alkalies, aliphatic amines, amides, nitric acid, sulfuric acid. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). These reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid and can explode when heated. Many phenols form metal salts that may be detonated by mild shock
