Abstract

Sposób epoksydacji limonenu za pomocą 60% wodnego roztworu nadtlenku wodoru, lub roztworu wodoronadtlenku t-butylu w dekanie w obecności katalizatorów tytanowo-silikalitowych oraz rozpuszczalnika, polega na tym, że proces prowadzi się pod ciśnieniem autogenicznym, w temperaturze 150 - 160°C, przy stosunku molowym limonen/utleniacz 1:1, w czasie reakcji 3h, zaś jako katalizatory tytanowo-silikalitowe stosuje się katalizatory TS-1, TS-2, Ti-Beta, Ti-MCM-41, Ti-MWW i Ti-SBA-15 w ilości 3% wagowych w mieszaninie reakcyjnej. Proces epoksydacji limonenu prowadzi się w obecności metanolu jako rozpuszczalnika przy jego stężeniu w mieszanie reakcyjnej 80% wagowych, stosując intensywność mieszania 500 obr/min. Stosuje się 5M roztwór wodoronadtlenku t-butylu w dekanie. Surowce wprowadza się do autoklawu w następującej kolejności: limonen, metanol, katalizator i na końcu utleniacz.The method of epoxidation of limonene with a 60% aqueous solution of hydrogen peroxide, or a solution of t-butyl hydroperoxide in decane in the presence of titanium silicalite catalysts and a solvent consists in the fact that the process is carried out under autogenic pressure, at a temperature of 150 - 160 ° C, with 1: 1 molar ratio of limonene / oxidant, 3h reaction time, while TS-1, TS-2, Ti-Beta, Ti-MCM-41, Ti-MWW and Ti-SBA-15 catalysts are used as titanium-silicon catalysts in an amount of 3% by weight in the reaction mixture. The limonene epoxidation process is carried out in the presence of methanol as a solvent at its concentration in a reaction mixture of 80% by weight, using a stirring intensity of 500 rpm. A 5M solution of t-butyl hydroperoxide in decane is used. The raw materials are introduced into the autoclave in the following order: limonene, methanol, catalyst and finally the oxidant.
