Abstract:
A process comprising catalytically reacting at least one organic compound constituting all or part of a liquid organic phase, in the presence of a polar liquid phase containing a catalyst composition, wherein:the polar liquid phase containing a catalyst composition results from a mixture of at least one catalyst compound and at least one non-aqueous ionic medium, which is sufficiently immiscible with the organic phase that the polar and organic phases can be separated by decanting,the organic phase and the polar phase are circulated in counter-current contact in at least two treatment loops connected in series, each loop comprising at least one reaction zone containing a reaction medium of the organic and polar phases in contact and connected to the reaction zone, at least one separation zone for separating the organic and polar phases by decanting,a feed containing the organic compound is supplied to the reaction zone of a first treatment loop and the polar phase is supplied to the reaction zone of a second treatment loop,polar phase separated in the separation zone of the second treatment loop is sent to the reaction zone of the first treatment loop, andorganic phase separated in the separation zone of the first treatment loop is sent to the reaction zone of the second treatment loop.
