Allgemeine Beschreibung
Clear colorless to pale yellow viscous liquid with a characteristic odor.
Air & Water Reaktionen
Very hygroscopic. Soluble in water.
Reaktivität anzeigen
Monoacetin may hydrolyze in acid or alkaline aqueous solutions. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. They exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Brandgefahr
Monoacetin is probably combustible.
