Maleic acid dibutyl ester is a chemical compound in the group of carboxylic acid esters.

Preparation

Maleic acid dibutyl ester can be prepared by the reaction of maleic acid anhydride and 1-butanol in presence of p-toluenesulfonic acid.^[3]^[4]

Properties

Maleic acid dibutyl ester is a flammable, hard to ignite, oily, colorless to yellowish liquid with a characteristic odor, which has very low solubility in water.

Uses

Maleic acid dibutyl ester is mainly used as a plasticizer for aqueous dispersions of copolymers with vinyl acetate and as an intermediate in the preparation of other chemical compounds.^[5]
