Abstract
Przedmiotem zgłoszenia jest sposób utleniania limonenu, za pomocą 60% wodnego roztworu nadtlenku wodoru, w obecności katalizatora oraz metanolu jako rozpuszczalnika. Sposób ten charakteryzuje się tym, że jako katalizator stosuje się montmorylonit w ilości 3% wagowych w mieszaninie reakcyjnej. Jako źródło montmorylonitu stosuje się bentonit, który oczyszcza się w następujący sposób: umieszcza się go w wodzie destylowanej i miesza w celu uzyskania 10% dyspersji, którą poddaje się wirowaniu, oddziela ciało stałe, suszy się i rozciera na proszek. Proces utleniania prowadzi się przy stężeniu metanolu w mieszanie reakcyjnej wynoszącym 80% wagowych, w temperaturze 40 - 100°C, pod ciśnieniem atmosferycznym, przy stosunku molowym limonen/utleniacz 1:1, w czasie reakcji od 30 minut do 48 godzin, stosując intensywność mieszania 500 obr/min.The subject of the application is a method of oxidizing limonene with a 60% aqueous hydrogen peroxide solution in the presence of a catalyst and methanol as a solvent. This process is characterized in that 3% by weight of montmorillonite is used as the catalyst in the reaction mixture. As a source of montmorillonite, bentonite is used, which is purified as follows: it is placed in distilled water and mixed to obtain a 10% dispersion, which is centrifuged, separates the solid, dried and triturated. The oxidation process is carried out at a methanol concentration of 80% by weight in the reaction mixture, at a temperature of 40-100 ° C, at atmospheric pressure, a limonene / oxidant molar ratio of 1: 1, during a reaction time of 30 minutes to 48 hours, using stirring intensity 500 rpm
