EXTRACTION OF CARBONIC ACID FROM ITS MAGNETIC SALTS BY DEPOSITION USING CHLRIDE HYDROGENIC ACID, SUITABLE FOR SEPARATION OF THE PRODUCT OF REACTION FROM THE ENZYMATIVE BULON

摘要

The invention provides a method for producing succinic acid, comprising the steps of providing magnesium succinate; acidifying magnesium succinate with hydrochloric acid (HCl), whereby a solution containing succinic acid and magnesium chloride (MgCl) is obtained; possibly a concentration step in which a solution containing succinic acid and MgCl is concentrated; precipitating succinic acid from a solution containing succinic acid and MgCl, whereby a succinic acid precipitate and a MgCl solution are obtained. It was found that the addition of HCl to the magnesium salt of succinic acid and the subsequent precipitation of succinic acid from this solution leads to a very efficient separation of succinic acid from a solution of magnesium succinate.
