Abstract: A PROCESS FOR THE OXIDATION OF ALKYLPYDRIDINES OF THE FORMULA

(R)M-PYRIDINE

WHEREIN R IS AN ALKYL RADICAL CONTAINING 1 TO 2 CARBON ATOMS AND M IS AN INTEGER OF 1 TO 4, INTO CORRESPONDING PYRIDINECARBOXYLIC ACIDS, WHICH PROCESS COMPRISES REACTTING SAID ALKYLPYRIDINE WITH A COBALT SALT IN A MOLAR RATIO OF ALKYLPYRIDINE TO COBALT SALT OF LOWER THAN 2 WHILE MAINTAINING SUCH A CONCENTRATION OF COBALTIC SALT THAT 2X-A IS BETWEEN 0.1 AND 1.5 X AND A BEING RESPECTIVELY THE MOLARITY OF COBALTIC IONS AND OF SAID COBALT SALT IN THE REACTION MIXTURE, AT A TEMPERATURE OF BETWEEN20 AND 150*C., IN AN ALIPHATAIC CARBOXYLIC ACID HAVING FRONM 2 TO 4 CARBON ATOMS AND IN THE PRESENCE OF MOLECULAR OXYGEN AT A PARTIAL PRESSURE OF 0.2 TO 20 ATMOSPHERES.

Abstract: A PROCESS FOR THE OXIDATION OF QUINOLINE INTO QUINOLINIC ACID WHICH COMPRISES REACTING QUINOLINE WITH A COBALT SALT IN A MOLAR RATIO OF QUINOLINE TO COBALT SALT LOWER THAN 2, WHILE MAINTAINING A CONCENTRATION OF COBALTIC IONS SUCH THAT 2X-A IS BETWEEN 0.1 AND 1.5, X AND A BEING RESPECTIVELY THE MOLARITY OF SAID COBALTIC IONS AND SAID COBALT SALT IN THE REACTION MIXTURE, SUCH REACTION BEING CARRIED OUT AT A TEMPERATURE BETWEEN 40 AND 150*C. IN THE PRESENCE OF AN ALIPHATIC CARBOXYLIC ACID HAVING FROM 2 TO 4 CARBON ATOMS AND IN THE PRESENCE OF MOLECULAR OXYGEN AT A PARTIAL PRESSURE OF FROM 0.2 TO 20 ATMOSPHERES.
