Chlorate ion → Quinolinic Acid

참여 물질

반응 단계

In another example of a preferred embodiment of the process, a sodium chlorate solution is added in small increments to a mixture of the other components, including copper oxide, which has been previously mixed and heated to reaction temperature (99°-101° C.). The acid concentration in the mixture is about 5 equivalents of acid per liter. The total chlorate addition will provide a chlorate molar excess of about 18% relative to the quinoline present. An exotherm becomes apparent after 6-8% of the chlorate has been added, and soon thereafter a suspension of copper quinolinate develops. Total chlorate addition is completed in 2-4 hours with total reaction time of 10-12 hours. The product, crude copper salt of pyridine-2,3-dicarboxylic acid, is isolated by filtration.
