摘要： The invention pertains to a method for preparing succinic acid comprising the steps of - providing an aqueous magnesium succinate solution to an acidification step, wherein the magnesium succinate solution is acidified by the addition of hydrogen chloride, thereby obtaining an aqueous solution comprising succinic acid and magnesium chloride; - subjecting an aqueous solution comprising succinic acid and magnesium chloride derived from the acidification step to a treatment step with active carbon, - precipitating succinic acid from an aqueous mixture comprising succinic acid and magnesium chloride resulting from the active carbon treatment step in a precipitation step to form solid succinic acid and a magnesium chloride solution, - separating the solid succinic acid from the magnesium chloride solution - subjecting the magnesium chloride solution to a thermal decomposition at a temperature of at least 300°C, thereby decomposing the magnesium chloride to magnesium oxide and hydrogen chloride, and - recycling the hydrogen chloride generated in the thermal decomposition step to the acidification step. It has been found the method according to the invention leads to succinic acid crystals with better properties than a comparable method wherein no active carbon treatment is used.
