CA 2010062

The invention provides a process for preparing an ester by reacting a C7 - C36 mono- or dicarboxylic acid and a C2 - C8 monoalcohol in the presence of a lipase catalyst whereby water of reaction is removed by azeotropic distillation of a mixture of C2 - C8 monoalcohol and water. Preferably the azeotropic distillation of alcohol and the addition of alcohol are carried out at substantially the same rates and under reduced pressure. The process can be conducted in a single vessel system at a temperature below 80-C. Esterification and azeotropic distillation can also be are carried out in separate vessels in which case higher temperatures and higher pressures can be applied.

Avec cette invention, on divulgue un procédé pour préparer un ester en faisant réagir un acide mono-carboxylique ou di-carboxylique en C7-C36 avec un mono-alcool en C2-C8, en présence d'une lipase catalysante. Au cours de ce procédé, l'eau produite par la réaction est éliminée par distillation azéotropique d'un mélange de mono-alcool en C2-C8 et d'eau. De préférence, on réalise la distillation azéotropique de l'alcool et on ajoute de l'alcool à des vitesses sensiblement égales et sous pression réduite. Ce procédé peut être réalisé dans un réacteur unique, à une température inférieure à 80 .degré.C. On peut aussi réaliser l'estérification et la distillation azéotropique dans des récipients séparés, dans ce cas on peut utiliser des températures et des pressions plus élevées.
