Abstract
Przedmiotem zgłoszenia jest sposób epoksydacji limonenu za pomocą 60% wodnego roztworu nadtlenku wodoru w obecności katalizatorów tytanowo-silikalitowych Ti-MCM-41 i Ti-SBA-15 oraz rozpuszczalnika, który charakteryzuje się tym, że proces prowadzi się z użyciem takich rozpuszczalników, jak toluen, acetonitryl, etanol i izopropanol, przy ich stężeniu w mieszanie reakcyjnej wynoszącym 80% wagowych, w temperaturze 0-120°C. Proces prowadzi się pod ciśnieniem atmosferycznym, przy stosunku molowym limonen/utleniacz 1:1, w czasie reakcji od 15 minut do 48 godzin, z udziałem katalizatorów tytanowo-silikalitowych w ilości 3% wag. w mieszaninie reakcyjnej, stosując intensywność mieszania 500 obr/min. Surowce wprowadza się do reaktora szklanego w następującej kolejności: limonen, rozpuszczalnik, katalizator i na końcu utleniacz.The subject of the application is a method of epoxidation of limonene with a 60% aqueous solution of hydrogen peroxide in the presence of Ti-MCM-41 and Ti-SBA-15 titanium-silica catalysts and a solvent, which is characterized by the fact that the process is carried out using solvents such as toluene , acetonitrile, ethanol and isopropanol, at a concentration in the reaction mixture of 80% by weight, at a temperature of 0-120 ° C. The process is carried out at atmospheric pressure, 1: 1 molar ratio of limonene / oxidant, during the reaction time from 15 minutes to 48 hours, with the use of titanium-silicalite catalysts in an amount of 3 wt. in the reaction mixture using a stirring intensity of 500 rpm. The raw materials are introduced into the glass reactor in the following order: limonene, solvent, catalyst and finally the oxidant.
