Abstract
An esterification process, characterized in that a carboxylic acid free of active substituents of reaction with an alkanol is reacted in a reaction zone, with at least one of the two reactants being monofunctional and the boiling point of the alcohol being lower than that of the ester produced in the reaction, at pressure higher than atmospheric and at a temperature substantially comprised between 100ºC and 300º c, distill the unreacted alcohol and water byproduct, from the reaction product and react the distillation residue in a reaction zone with more than said alcohol at higher than atmospheric pressure and at a temperature substantially comprised between 100ºC and 300º c, the total reaction time between the carboxylic acid and the alcohol being at elevated temperature and pressure of about 1 to 5 minutes.
