Description

Dimethyl maleate is acts as a dienophile involved in ultrasonic irradiation promoted Diels-Alder reaction with substituted furans. It is widely used as an intermediate and additive for pharmaceuticals, copolymers, pigments, plastics, paints, adhesives and agrochemicals. As an internal modifier, it increases the glass transition temperature of styrene or vinyl chloride polymer. It plays a vital role to improve the hardness and toughness of polymer films such as copolymers of vinyl acetate.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Le maléate de diméthyle est un diénophile impliqué dans l’irradiation ultrasonique qui favorise la réaction de Diels-Alder avec les furanes substitués. Il est largement utilisé comme intermédiaire et additif pour les produits pharmaceutiques, les copolymères, les pigments, les plastiques, les peintures, les adhésifs et les produits agrochimiques. En tant que modificateur interne, il augmente la température de transition en verre du styrène ou du chlorure de vinyle polymère. Il joue un rôle essentiel pour améliorer la dureté et la dureté des films polymères tels que les copolymères de l’acétate de vinyle.

Solubilité
Miscible à l’eau.

Remarques
Incompatible avec les acides, les bases, les agents oxydants et les agents réducteurs.
