| titleOfInvention | PROCESS FOR SYNTHESIS OF CITRIC ACIDS |
| abstract | The object of the invention is an economical process for the production of citrazine acid. The problem to be solved is to produce citrazine acid from an easily accessible, well-defined citric acid derivative while avoiding the intermediate citrazine acid amide in good purity. The essence of the invention is characterized in that symm.-Citronensaeuredimethylester with NH3 to symm. Diamid is reacted, which is then cyclized in acid to Citrazinsaeure. |
