Abstract

Przedmiotem zgłoszenia jest sposób epoksydacji limonenu, za pomocą 5M roztworu wodoronadtlenku t-butylu w dekanie w obecności katalizatorów tytanowo - silikalitowych Ti-MCM-41 i Ti-MWW oraz metanolu jako rozpuszczalnika. Sposób charakteryzuje się tym, że proces prowadzi się pod ciśnieniem atmosferycznym w temperaturze 20 - 80°C lub autogenicznym w temperaturze 90 - 140°C, przy stosunku molowym limonen/utleniacz 1 : 1 - 5 : 1, w czasie reakcji 6 - 24 h, przy stężeniu metanolu w mieszanie reakcyjnej 60 - 90% wagowych, zaś katalizator tytanowo - silikalitowy stosuje się w ilości 1 - 6% wagowych w mieszaninie reakcyjnej. Korzystnie proces epoksydacji limonenu prowadzi się stosując intensywność mieszania 500 obr/min. Korzystnie surowce wprowadza się do autoklawu w następującej kolejności: limonen, metanol, katalizator i na końcu utleniacz.The subject of the application is a method of limonene epoxidation, using a 5M solution of t-butyl hydroperoxide in decane in the presence of Ti-MCM-41 and Ti-MWW titanium-silica catalysts and methanol as a solvent. The method is characterized in that the process is carried out at atmospheric pressure at 20-80 ° C or autogenous at 90-140 ° C, with a molar ratio of limonene / oxidant 1: 1 - 5: 1, during a reaction time of 6 - 24 h at a methanol concentration of 60-90% by weight in the reaction mixture, while a titanium-silicalite catalyst is used in an amount of 1-6% by weight in the reaction mixture. Preferably the limonene epoxidation process is carried out using a stirring intensity of 500 rpm. Preferably, the raw materials are introduced into the autoclave in the following order: limonene, methanol, catalyst and finally the oxidant.
