Abstract

Przedmiotem zgłoszenia jest sposób izomeryzacji limonenu, który polega na tym, że w obecności katalizatora, pod ciśnieniem atmosferycznym, jako katalizator stosuje się katalizator tytanowo-silikalitowy Ti-SBA-15 w ilości 5 - 15% wagowy w mieszaninie reakcyjnej. Proces izomeryzacji prowadzi się w temperaturze 140 - 160°C, w czasie od 0,5 do 23 godzin, stosując intensywność mieszania 500 obr/min. Do reaktora wprowadza się w pierwszej kolejności limonen, a później katalizator.The subject of the application is a method of isomerization of limonene, which consists in the fact that in the presence of a catalyst at atmospheric pressure, a titanium-silicalite catalyst Ti-SBA-15 in the amount of 5 - 15% by weight in the reaction mixture is used. The isomerization process is carried out at a temperature of 140 - 160 ° C for 0.5 to 23 hours using a stirring intensity of 500 rpm. Limonene is introduced into the reactor first, followed by the catalyst.
