Abstract

L'invention concerne un procédé continu de préparation de lactate d'éthyle par estérification d'acide lactique au moyen de l'éthanol, en présence d'un catalyseur qui consiste à extraire en continu, du milieu réactionnel d'estérification à un taux de conversion partielle de l'acide lactique, un mélange comprenant du lactate d'éthyle, de l'éthanol, de l'eau et divers produits lourds puis à soumettre ce mélange à une séparation flash, sous pression réduite, de laquelle sort un flux de tête comprenant un mélange de lactate d'éthyle, d'éthanol et d'eau lequel mélange alimente, dans sa partie basse, une colonne de distillation fractionnée.
