Abstract
Przedmiotem zgłoszenia jest sposób epoksydacji 1,5,9-cyklododekatrienu w fazie ciekłej, gdzie mieszanina reakcyjna składa się z wodnego roztworu nadtlenku wodoru, katalizatora heterogenicznego, rozpuszczalnika i 1,5,9-cyklododekatrienu, przy czym stosunek molowy 1,5,9-cyklododekatrienu do nadtlenku wodoru wynosi od 0,5 do 2, a proces epoksydacji prowadzi się w atmosferze powietrza i pod ciśnieniem atmosferycznym z intensywnością mieszania 500 obr./min, w czasie od 15 minut do 240 minut. Sposób charakteryzuje się tym, że jako katalizator stosuje się materiał mezoporowaty W-SBA-15 o zawartości 2% wagowych wolframu, w ilości od 0,5% do 5% wagowych w mieszaninie reakcyjnej. Jako rozpuszczalnik stosuje się izopropanol lub aceton w ilości od 85% do 90% wagowych w mieszaninie reakcyjnej, zaś proces epoksydacji prowadzi się w temperaturze od 20°C do 60°C.The subject of the application is a method for the epoxidation of 1,5,9-cyclododecatriene in the liquid phase, where the reaction mixture consists of an aqueous solution of hydrogen peroxide, a heterogeneous catalyst, a solvent and 1,5,9-cyclododecatriene, with a molar ratio of 1,5,9- cyclododecatriene to hydrogen peroxide is from 0.5 to 2, and the epoxidation process is carried out in an air atmosphere and at atmospheric pressure with a stirring intensity of 500 rpm, for a time from 15 minutes to 240 minutes. The method is characterized by the fact that the mesoporous material W-SBA-15 with a tungsten content of 2% by weight is used as a catalyst, in an amount from 0.5% to 5% by weight in the reaction mixture. Isopropanol or acetone is used as a solvent in an amount of 85% to 90% by weight in the reaction mixture, and the epoxidation process is carried out at a temperature of 20°C to 60°C.
