Title (EN) RECYCLING OF IONIC LIQUID CATALYST
(FR) RECYCLAGE D'UN CATALYSEUR LIQUIDE IONIQUE
Abstract:
(EN) Provided is a process for safely transporting or recycling an ionic liquid catalyst based on chloroaluminates. The process comprises mixing a secondary alcohol with an ionic liquid based on a chloroaluminate and allowing a reaction to occur forming an aluminum chloride adduct precipitate. The precipitate is filtered and the secondary alcohol removed, leaving a solid salt. This solid salt is the ionic liquid catalyst absent aluminum chloride, for example, Nbutylpyridinium chloride. This salt is recycled to the reactor. AlCl13 is added to the salt prior to introduction into the reactor to remake the ionic liquid catalyst, for example, Nbutylpyridinium heptachloroaluminate.
(FR) La présente invention concerne un procédé permettant de transporter ou de recycler en toute sécurité un catalyseur liquide ionique à base de chloroaluminate. Ce procédé consiste à mélanger un alcool secondaire avec un liquide ionique basé sur un chloroaluminate, les laisser réagir pour former un précipité d'addition de chlorure d'aluminium, filtrer ce précipité et retirer l'alcool secondaire pour obtenir un sel solide. Ce sel solide, qui est le catalyseur liquide ionique dont le chlorure d'aluminium a été retiré, par exemple du chlorure de N-butylpyridinium, est recyclé dans le réacteur. De l'AlCl3 y est préalablement ajouté pour reconstituer le catalyseur liquide ionique, par exemple de l'heptachloroaluminate de N-butylpyridinium.
