Method for the manufacture of an ammonium sulfate composition |
| abstract |
The present invention describes a method for the manufacture of an ammonium sulfate composition having a total organic carbon (TOC) content of 1% by weight or less than 1 % by weight, based on the total weight of the composition, comprising the following steps: a) reacting i) waste sulfuric acid comprising an organic tertiary amines with ii) ammonia in an amount sufficient to obtain a pH of 9.5 or higher b) separating the organic tertiary amine from the reaction mixture obtained in step a) wherein during the separation the pH of the reaction mixture is maintained at a pH higher than 10 and c) optionally reducing the content of water and/or other volatile components from the aqueous solution comprising the ammonium sulfate. |
