Process for the preparation of malonic and alkylmalonic acids |
| abstract |
The invention relates to a new process for the production of malonic acid andnAlkylmalonic acids by acid catalyzed saponification of the corresponding esters. Atnthe process is an aqueous mixture of the esters on acidic ion exchangersnsaponified at an elevated temperature, the alcohol formed distilling off the waternseparated with the help of organic solvents and the products from themnSolvents are crystallized. |
