Abstract
The invention provides a method for preparing a succinic acid, which method includes the steps of: providing magnesium succinate; acidifying the magnesium succinate with hydrochloric acid (HCl), thereby obtaining a solution including succinic acid and magnesium chloride (MgCl); optionally a concentration step, wherein the solution including succinic acid and MgClis concentrated; precipitating succinic acid from the solution including succinic acid and MgCl, thereby obtaining a succinic acid precipitate and a MgClsolution. The addition of HCl to a magnesium salt of succinic acid and subsequent precipitation of succinic acid from the solution leads to a very efficient separation of succinic acid from a magnesium succinate solution.
