METHOD FOR PRODUCTION OF PYRAZINAMIDE AND CATALYST FOR ITS REALISATION Russian patent published in 2009 - IPC C07D241/12 B01J23/22 B01J21/06

Abstract RU 2376296 C1

FIELD: medicine.

SUBSTANCE: method is described for production of pyrazinamide by oxidising ammonolysis of methyl pyrazine, which is executed in presence of water vapors and nitrogen in gas phase with further extraction of pyrazinamide in single stage, and catalyst is used with the following composition, wt %: 5-75 V₂O₅ and 95-25 TiO₂ (anatase), with specific surface of 10-120 m²/g.

EFFECT: production of pyrazinamide from methyl pyrazine in single stage, elimination of hazardous gas emissions.
