Abstract

Procédé de production d'epsilon-caprolactame à partir de cyclohexanone oxime par réarrangement en phase gazeuse sur un catalyseur en dit fluidisé contenant de l'oxyde de bore, dans lequel les résidus de la distillation de la cyclohexanone oxime sont introduits dans la réaction sous la forme liquide et dans lequel 5 à 500 fois leur quantité de cyclohexanone oxime à l'état de vapeur et au moins 50 fois leur quantité de gaz inerte sont présents au cours de la réaction.
