GENERAL DESCRIPTION OF MALEIC ACID |
||
|
Maleic
acid (also called cis-butenedioic acid), a white crystals
easily soluble in water, acetone, and alcohol, is an
unsaturated organic dibasic acid which carboxylic acid
groups are next to each other in the cis form. Its trans
form isomer is fumaric acid, both are used in making
polyesters, alkyd resins, plasticizers and lubricating
oils. Maleic acid is prepared commercially by the
oxidation of benzene. Maleic acid is used in the
manufacture of fumaric acid and other chemical products
as a carboxylating agent. It is used as an oil
and fat preservative and food acidulant. UNSATURATED ALIPHATIC CARBOXYLIC ACIDS (SHORT CHAIN) | ||
