Abstract

Przedmiotem zgłoszenia jest sposób izomeryzacji limonenu, w obecności katalizatora tytanowo-silikalitowego, pod ciśnieniem atmosferycznym, który charakteryzuje się tym, że jako katalizator stosuje się katalizator Ti-MCM-41 w ilości 10 - 15% wagowy w mieszaninie reakcyjnej. Proces izomeryzacji prowadzi się w temperaturze 150 - 170°C, w czasie od 0,5 do 24 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, in the presence of a titanium-silicalite catalyst at atmospheric pressure, which is characterized in that the catalyst used is a Ti-MCM-41 catalyst in an amount of 10-15% by weight in the reaction mixture. The isomerization process is carried out at a temperature of 150-170 ° C for 0.5 to 24 hours using a stirring intensity of 500 rpm. Limonene is introduced into the reactor first, followed by the catalyst.
