Dihydrocoumarin Chemical Properties,Uses,Production
Occurrence
Reported found in Melilotus officinalis, from which it may be extracted by water distillation.
Definition
ChEBI: A chromanone that is the 3,4-dihydro derivative of coumarin.
Preparation
Dihydrocoumarin is synthesized by reduction of coumarin under pressure in the presence of nickel at 160 to 200°C or in the presence of Pd-BaSO4 in alcoholic solution.
General Description
Viscous, almost colorless liquid, solidifying
in the cold, melting at 23° C. Sp. Gr. 1.19.
B.P. 272° C.
Slightly soluble in water, soluble in alcohol,
miscible with oils.
Sweet-herbaceous, nutlike, haylike odor,
usually described as "coumannic" or "tobacco-like".
Air & Water Reactions
Solutions of the chemical in water are stable for less than two hours. Insoluble in water.
Reactivity Profile
Hydrocoumarin is a lactone (behaves as an ester). 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. Hydrocoumarin may hydrolyze under alkaline or acidic conditions.
Fire Hazard
Hydrocoumarin is combustible.
