디하이드로코마린(3,4-) C화학적 특성, 용도, 생산
출처
Reported found in Melilotus officinalis, from which it may be extracted by water distillation.정의
ChEBI: A chromanone that is the 3,4-dihydro derivative of coumarin.제조 방법
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.일반 설명
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".
공기와 물의 반응
Solutions of the chemical in water are stable for less than two hours. Insoluble in water.반응 프로필
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.화재위험
Hydrocoumarin is combustible.디하이드로코마린(3,4-) 준비 용품 및 원자재
