Diethyl maleate Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Chemical Properties

It is a clear liquid between the temperatures of -10°C (pour point) and 225°C (boiling point). Diethyl maleate is soluble in alcohol and ether is insoluble in water.

Occurrence

Has apparently not been reported to occur in nature.

Uses

Diethyl maleate is unsaturated polyester resins that are used in applications, such as reinforced glass fiber for boats, piping, bathtubs, roof panels, etc., and as protective coatings, finishes, and lacquers.

Uses

In organic synthesis.

Production Methods

Diethyl maleate is formed by the direct esterification of maleic acid with ethyl alcohol.

Preparation

By direct esterification of maleic acid with ethyl alcohol (Arctander, 1969).

Metabolism

α/β-Unsaturated compounds, such as diethyl maleate, react enzymically with gluta thione. The reaction has been demonstrated in fractions of rat liver (Boyland & Chasseaud, 1967) and avian liver (Wit & Snel, 1968). The enzyme differs from other known S-alkyl, S-aryl and S- epoxide transferase enzymes responsible for glutathione-conjugate formation (Boyland & Chasseaud, 1967). Diethyl maleate, administered parenterally to rats, reduced the hepatic glutathione content (Boyland & Chasseaud, 1970; Varga, Fischer & Szily, 1974). The latter workers also showed that diethyl maleate pretreatment of rats inhibited the glutathione conjugation of subsequently-adminis tered bromsulphthalein.
