  • Process for esterification in a chromatographic reactor
    Patent number: 6586609
    Abstract: Process for the esterification of organic acids with alcohols in a reactor of the chromatographic type in which the heterogeneous solid phase is capable of acting both as an esterification catalyst and as a means exhibiting preferential adsorption towards one of the reaction products (typically water). The process to which the present invention relates is particularly improved compared with conventional technology owing to the use, as the means for regenerating the catalyst, of a desorbent to which has been added a second compound, generally the anhydride of the acid used in the esterification reaction, which, by chemical reaction, completes the removal of the adsorbed water.
