Allgemeine Beschreibung
Colorless liquid.
Air & Water Reaktionen
Water soluble.
Reaktivität anzeigen
Dimethyl succinate reacts with acids to liberate heat along with methanol and succinic acid. May react with strong oxidizing acids to liberate enough heat to ignite the reaction products. Heat is also generated by the interaction with caustic solutions. Flammable hydrogen is generated with alkali metals and hydrides.
Health Hazard
May be harmful by inhalation, ingestion or skin absorption. May cause irritation.
Brandgefahr
Dimethyl succinate is combustible. Vapor forms explosive mixtures with air.
