Abstract
Przedmiotem zgłoszenia jest sposób izomeryzacji alfa-pinenu, w obecności katalizatora, pod ciśnieniem atmosferycznym, w temperaturze 80 - 180°C, z intensywnością mieszania 500 obr/minutę. Przedmiotowy sposób charakteryzuje się tym, że jako katalizator stosuje się montmorylonit utarty do rozmiaru ziaren < 0,25 mm oraz wysuszony w 100°C, w ilości 2,5 - 15% wagowych w mieszaninie reakcyjnej. Stosuje się montmorylonit o następującym składzie: SiO2 - 60% wagowy, Al2O3 -13% wagowy, CaO - 4,1% wagowy, Fe2O3 - 4,2% wagowy, MgO - 1,5% wagowy, Na2O - 0,15% wagowy, MnO2 - 0,09% wagowy, S-1,1% wagowy, P-1,7% wagowy, TiO2 - 0,6% wagowy. Proces izomeryzacji prowadzi się w czasie od 15 minut do 24 godzin. Do reaktora wprowadza się w pierwszej kolejności alfa-pinen, a później katalizator.The subject of the application is a method of isomerization of alpha-pinene, in the presence of a catalyst, at atmospheric pressure, at a temperature of 80 - 180 ° C, with a stirring intensity of 500 rpm. The present process is characterized in that the catalyst used is montmorillonite, ground to a grain size <0.25 mm and dried at 100 ° C, in an amount of 2.5 - 15% by weight in the reaction mixture. Montmorillonite is used with the following composition: SiO2 - 60% by weight, Al2O3 -13% by weight, CaO - 4.1% by weight, Fe2O3 - 4.2% by weight, MgO - 1.5% by weight, Na2O - 0.15% by weight , MnO2 - 0.09% by weight, S-1.1% by weight, P-1.7% by weight, TiO2 - 0.6% by weight. The isomerization process is carried out for 15 minutes to 24 hours. Alpha-pinene is introduced into the reactor first, and then the catalyst.
