CONSTITUTION:In the preparation of an ester by the reaction of an organic carboxylic acid or its anhydride with an alcohol, the vapor of the alcohol and by-produced water distilled out from the reactor is condensed at a temperature higher than the boiling point of water under the pressure in...
in a molar ratio of 1:0.5-2 at 0-100 deg.C in a solvent to prepare the corresponding ester. The tetraalkylammonium polyhalide as an oxidizing agent includes benzyltrimethylammonium tribromide. The method gives the corresponding hexyl hexanoate from n-hexyl alcohol. The employment of the ...
