Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania nadkwasu n-dekanowego polegający 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. Później mieszanina poreakcyjna jest mieszaną korzystnie w sposób ciągły przez okres od 40 do 60 minut, następnie do mieszanej poreakcyjnej mieszaniny wprowadzana jest jednorazowo woda, z zachowaniem stężenia końcowego kwasu siarkowego użytego do rozpuszczenia kwasu n-dekanowego nie niższego niż 12% i temperatury procesu nie przekraczającej 43°C. Po pełnym stopieniu osadu nadkwasu n-dekanowego z powstałej emulsji krystalizuje się nadkwas i po całkowitym jego wykrystalizowaniu powstały osad jest odfiltrowywany, przemywany wodą do odczynu obojętnego, a następnie suszony.The subject of the application is a method for the preparation of 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 post-reaction mixture is stirred, preferably continuously for a period of 40 to 60 minutes, then water is introduced into the mixed post-reaction mixture once, with the final concentration of sulfuric acid used to dissolve n-decanoic acid not lower than 12% and the process temperature not exceeding 43 ° C. After the n-decanoic peracid precipitate has fully melted, the peracid is crystallized from the resulting emulsion, and after its complete crystallization, the resulting precipitate is filtered off, washed with water until it is neutral, and then dried.
