2-sec-Butylphenol Usage And Synthesis

Chemical Properties

colourless to light yellow liquid

Chemical Properties

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

Uses

Chemical intermediate in preparation of resins, plasticizers, surface-active agents.

Uses

Herbicide, Insecticide, Polymerization Inhibitor, Stabilizer Intermediate

Uses

A chemical intermediate in the production of resins, plasticizers, and other products

Definition

ChEBI: A member of the class of phenols that is phenol carrying a butan-2-yl group at position 2.

General Description

Clear colorless liquid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Phenols, such as 2-sec-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.

Hazard

Skin, eye, and upper respiratory tract irri- tant.

Health Hazard

o-sec-Butylphenol is a skin, eye, and respiratory irritant.
Acute occupational exposures have resulted in mild respiratory irritation as well as skin burns.

Fire Hazard

2-sec-Butylphenol is combustible.

Flammability and Explosibility

Not classified

Safety Profile

A poison by intraperitoneal and intravenous routes. Moderately toxic by ingestion and skin contact. A severe skin and eye irritant. Combustible when exposed to heat or flame. To fight fire, use foam, spray, CO2, dry chemical. When heated to decomposition it emits acrid and irritating fumes. 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

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
