Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania nadkwasu n-dekanowego który polega na tym, że kwas n-dekanowy rozpuszczany jest w kwasie siarkowym o stężeniu od 95 do 98%, przy zachowaniu stężenia masowego kwasu n-dekanowego w kwasie siarkowym od 36 do 53% wagowych, następnie mieszanina reakcyjna schładzana jest do temperatury nie wyższej niż 10°C, po czym do roztworu wprowadzany jest nadtlenek wodoru o stężeniu od 36 do 60%, przy zachowaniu stosunku molowego nadtlenku wodoru do kwasu n-dekanowego od 0,94:1 do 1,81:1 moli i temperatury reakcji nie przekraczającej 30°C, następnie mieszanina poreakcyjna jest kolejno mieszana, przemywana wodą, przy zachowaniu mieszania i temperatury nie przekraczającej 36°C, aż do uzyskania stężenia końcowego kwasu siarkowego powyżej 12% wagowych, a z otrzymanej zawiesiny odfiltrowywany jest osad, który poddawany jest dalszej obróbce.The subject of the application is a method of obtaining n-decanoic acid, which consists in dissolving n-decanoic acid in sulfuric acid with a concentration of 95 to 98%, while maintaining the mass concentration of n-decanoic acid in sulfuric acid from 36 to 53% by weight, then the reaction mixture is cooled to a temperature not exceeding 10 ° C, and then hydrogen peroxide with a concentration of 36 to 60% is introduced into the solution, maintaining the molar ratio of hydrogen peroxide to n-decanoic acid from 0.94: 1 to 1, 81: 1 mole and the reaction temperature not exceeding 30 ° C, then the reaction mixture is successively mixed, washed with water, with stirring and the temperature not exceeding 36 ° C, until the final sulfuric acid concentration is above 12% by weight, and the resulting suspension is filtered there is a sludge that undergoes further processing.
