Abstract
The present disclosure relates to processes for the separation of at least one di-carboxylic acid compound and/or at least one mono-carboxylic acid compound from a mixture. The separation processes involve contacting the mixture with an ion exchange medium to cause at least one of the mono- and/or di-carboxylic acid compounds to be retained by the medium, eluting at least one of the mono-carboxylic acid compound or the di-carboxylic acid compound using an eluent to form an eluate, wherein the eluate is enriched in at least one of the mono-carboxylic acid compound or di-carboxylic acid relative to the concentration of such eluted acid in the mixture having contacted the medium and wherein the eluent comprises an organic acid. The process has particular utility in the production of di-carboxylic acid compounds from glucose.
