Recovery of carboxylic acid from their magnesium salts by precipitation using hydrochloric acid, useful for fermentation broth work-up |
| abstract |
The invention provides a method for preparing a succinic acid, which method comprises the steps of - providing magnesium succinate; - acidifying the magnesium succinate with hydrochloric acid (HC1), thereby obtaining a solution comprising succinic acid and magnesium chloride (MgC12); - optionally a concentration step, wherein the solution comprising succinic acid and MgC12 is concentrated; - precipitating succinic acid from the solution comprising succinic acid and MgC12, thereby obtaining a succinic acid precipitate and a MgC12 solution. The inventors found that the addition of HC1 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. |
