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 faire réagir ledit acide lactique avec l'éthanol selon un rapport molaire initial éthanol/acide lactique au moins égal à 2,5, en présence d'un catalyseur, au reflux du milieu réactionnel qui se situe vers 100°C sous une pression absolue allant de 1,5 à 3 bars, ledit procédé étant caractérisé en ce que l'on extrait en continu, du milieu réactionnel d'estérification un mélange gazeux eau-éthanol proche de l'azéotrope ; puis que l'on déshydrate ce mélange gazeux directement au moyen de tamis moléculaires, puis que l'on récupère de ladite déshydratation un flux gazeux d'éthanol pouvant être recyclé au milieu réactionnel d'estérification et un flux constitué d'eau et d'éthanol qui est soumis à une distillation duquel on obtient de l'eau et un azéotrope eau-éthanol qui est injecté en tête de la colonne de distillation du mélange gazeux extrait du milieu réactionnel d'estérification ; puis que l'on extrait en continu du lactate d'éthyle brut qui est soumis à une purification de laquelle on obtient un lactate d'éthyle de haute pureté et des produits lourds.
