Process for the preparation of copper quinolinate |
| abstract |
A process for the preparation of copper quinolinate in which quinoline is oxidized by hydrogen peroxide in 10 to 30% sulfuric acid in the presence of copper sulfate at a temperature of 55° to 75° C., the molar ratio of sulfuric acid to quinoline being greater than 1:1. The concentration and amount of sulfuric acid enable greater control of the reaction temperature and result in copper quinolate in improved yield and purity. n Copper quinolinate is used to prepare quinolinic acid which is the starting material for some chromogenic materials used in the pressure-sensitive record material field. |
