Abstract
Procédé de déméthanolisation des solutions aqueuses résiduaires de la réaction de synthèse du chlorure de méthyle à partir d'acide chlorhydrique et de méthanol consistant à maintenir ladite solution en phase liquide et en l'absence de catalyseur à une température comprise entre 50 et 150 degrés C sous une pression inférieure à 8 bars. De préférence, la déméthanolisation est effectuée dans une colonne à distiller alimentée en solution aqueuse résiduaire au niveau de séparation de la zone d'épuisement et de la zone réactionnnelle.
