Abstract

Przedmiotem zgłoszenia jest sposób utleniania limonenu, za pomocą 60% nadtlenku wodoru w obecności katalizatorów tytanowo-silikalitowych Ti-MCM-41 i Ti-MWW oraz metanolu jako rozpuszczalnika. Sposób ten charakteryzuje się tym, że proces prowadzi się pod ciśnieniem atmosferycznym w temperaturze 20 - 80°C lub autogenicznym w temperaturze 90 - 150°C, przy stosunku molowym limonen/utleniacz 1:1 - 5:1, w czasie reakcji 6 - 24 godzin, przy stężeniu metanolu w mieszanie reakcyjnej 60 - 90% wagowych. 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 reaktora w następującej kolejności: limonen, metanol, katalizator i na końcu utleniacz.The subject of the application is a method of oxidizing limonene with 60% hydrogen peroxide in the presence of Ti-MCM-41 and Ti-MWW titanium-silica catalysts and methanol as a solvent. This method is characterized by the fact that the process is carried out at atmospheric pressure at 20 - 80 ° C or autogenous at 90 - 150 ° C, with a molar ratio of limonene / oxidant 1: 1 - 5: 1, during reaction 6 - 24 hours at a methanol concentration of 60-90% by weight in the reaction mixture. The 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 reactor in the following order: limonene, methanol, catalyst and finally the oxidant.
