| titleOfInvention | Method of producing isonicotinic acid |
| abstract | The invention concerns heterocyclic carbopic acids, in particular IZOSH1-COTINOVOH acid (IC), which is used in the synthesis of plant growth stimulants and anti-TB drugs. An increase in the productivity of the process and a decrease in the amount of wastewater reach- ing, with other conditions of 4-niaH-pyridip hydrolines (CP). The process is carried out in the presence of alkali (NaOH) at 50 - 30 C and a molar ratio of UTItNaOHiHgO 1: (1, 5 - 1.75): 10 - 17 for 9-10 minutes. IR is separated from the reaction mixture by acidification of the reaction mixture to a pH of 3.2 and the IR precipitate is separated. The yield is 99.2%, the productivity is 2.7 kg / l. The amount of wastewater decreases due to the production of a more concentrated IR solution. Table I and a yue 00 Cs3 „ |
