摘要

A process for manufacturing weakly dissociated water-soluble acids and in particular tartaric acid from a raw material containing one or more of its sparingly soluble salts, essentially characterized by being suspended in an aqueous solution of very dilute acid. Conveniently prepared and pulverized premiums, through which this suspension is passed from bottom to top on a layer of cation-changing resin, whose layer is contained in a container whose upper part has the shape of a diffuser, through which the liquid that exits above the aforementioned diffuser to a dryer or filter, and by re-introducing the solution leaving the dryer in the same circuit to ensure for a sufficient time the passage of the effluent on the cation exchange resin.
