The invention provides a process for the preparation of an alkylene glycol from an alkylene carbonate, wherein alkylene carbonate is hydrolysed in the presence of catalyst in a baffled reactor. The baffled reactor has at least four compartments, the compartments are formed by internal baffles and the internal baffles provide a sinuous route for reaction fluid through the reactor.

L'invention concerne un procédé pour la préparation d'un alkylène glycol à partir d'un carbonate d'alkylène, consistant à hydrolyser le carbonate d'alkylène en présence d'un catalyseur dans un réacteur à chicanes. Le réacteur à chicanes a au moins quatre compartiments, qui sont formés par des chicanes internes, ces dernière induisant un cheminement sinueux pour le fluide réactionnel dans le réacteur.
