Clear colorless liquid.??? ?? ??
Insoluble in water.?? ???
Methyl hexanoate is 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. Methyl hexanoate reacts with strong oxidizing agents and strong bases.????
Methyl hexanoate is combustible.Synthesis
Methyl caproate is synthesized by direct esterification of n-Caproic (n-Hexanoic) acid with Methanol, preferably under azeotropic conditions.Purification Methods
Pass it through alumina and distil it before use. [Beilstein 2 IV 921.]??????????? ?? ?? ? ???
