110-16-7 Usage

Reactivity Profile

Maleic acid is a colorless to white crystalline solid. Moderately toxic. When heated to decomposition Maleic acid emits irritating fumes and acrid smoke [Lewis, 3rd ed., 1993, p. 790].

Health Hazard

Inhalation causes irritation of nose and throat. Contact with eyes or skin causes irritation.

Fire Hazard

Special Hazards of Combustion Products: Irritating smoke containing maleic anhydride may form in fire.

Purification Methods

Crystallise the acid from acetone/pet ether (b 60-80o) or hot water. Dry it at 100o. [Beilstein 2 H 748, 2 I 303, 2 II 641, 2 III 1911, 2 IV 2199.]

Definition

ChEBI: A butenedioic acid in which the double bond has cis- (Z)-configuration.

General Description

Maleic acid is a colorless crystalline solid having a faint odor. Maleic acid is combustible though Maleic acid may take some effort to ignite. Maleic acid is soluble in water. Maleic acid is used to make other chemicals and for dyeing and finishing naturally occurring fibers.

Uses

manufacture of artificial resins; to retard rancidity of fats and oils in 1:10,000 (these are said to keep 3 times longer than those without the acid); dyeing and finishing wool, cotton, and silk; preparing the maleate salts of antihistamines and similar drugs.

Chemical Properties

Maleic acid, HOOCCH:CHCOOH, also known as maleinic acid and toxilic acid,is a colorless crystalline dibasic acid. It is soluble in water and alcohol. Maleic acid is used in manufacturing synthetic resins, in textile processing, and in preserving oils and fats.

Air & Water Reactions

Soluble in water.
