| titleOfInvention | Method for production of isovaleric acid |
| abstract | A method for producing isovalerianic acid by oxidation of isoamyl alcohol with higher nickel oxides under the conditions of their electrochemical regeneration on nickel-containing electrodes in an alkaline medium with an alternating current frequency of 1-0.0001 Hz is used, the alkali and isoamyl alcohol are dosed during processing, maintaining an alkali concentration of 1-6% The process is controlled by the magnitude of the voltage at the electrodes, the oxidation process is carried out at 20 - 80 ° С, current densities are 0.05 - 0.1 A / cm nickel concentration in terms of nickel sulfate 5 - 10 g / l After the reaction, the reaction mass is acidified to pH 2.5-3.0 and isovaleric acid is isolated. The technical result is enhanced when unreacted alcohol and by-products are distilled off with steam from the reaction mass before acidification. As a result of using the present invention, the quality of isovaleric acid is improved, the activity of the electrodes is increased, and in general the process becomes technologically advanced. |
