Hydrocoumarin Usage And Synthesis
Chemical Properties clear light yellow to brown liquid after melting
General Description White to pale yellow clear oily liquid with a sweet odor. Solidifies around room temperature.
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.
