Abstract

Sposób izomeryzacji alfa-pinenu w obecności katalizatora węglowego, według zgłoszenia, pod ciśnieniem atmosferycznym, w temperaturze 160°C, w czasie 4h, z intensywnością mieszania 400 obr./minutę, charakteryzuje się tym, że stosuje się katalizator węglowy otrzymany przez aktywację chemiczną roztworem KOH i karbonizację odpadowego materiału roślinnego. Odpadowy materiał roślinny suszy się przez 24 godziny w temperaturze pokojowej na powietrzu, następnie w suszarce w zakresie temperatur 50 - 70°C w czasie 24 godzin. Wysuszony materiał mieli się i miesza się intensywnie z roztworem KOH w ilości na każde 10 g materiału używa się 13 ml roztworu KOH, mieszaninę pozostawia się na 3 godziny w temperaturze pokojowej, następnie suszy się przez 19 godzin w temperaturze 150°C, po czym mieli się i karbonizuje w atmosferze azotu w temperaturze 800°C przez 1 godzinę. Następnie materiał chłodzi się do temperatury pokojowej w atmosferze gazu obojętnego, uciera się i płucze wodą, aby usunąć czynnik aktywujący. Nadmiar wody usuwa się, po czym tak otrzymany materiał węglowy zalewa się 1M roztworem HCl w ilości 100 ml roztworu na każde 2g materiału węglowego i pozostawieniu na 19 godzin w temperaturze pokojowej, następnie płucze się wodą destylowaną aż do osiągnięcia odczynu obojętnego, odparowuje się wodę. Odpadowy materiał roślinny jest w postaci świeżych skórek pomarańczy lub fusów kawy lub łusek nasion słonecznika, o następującym składzie w % wagowych: katalizator węglowy otrzymany ze skórek pomarańczy: Si — 0,264, S — 0,416, Cl — 0 182, K — 0,595, Ca — 0,289, katalizator węglowy z fusów kawy: Si — 0,268, S - 0,244 Cl — 0,696, K — 0,997, Ca — 0,000, katalizator węglowy otrzymany otrzymanego z łusek nasion słonecznika: Si — 0,246, S — 0,418, Cl — 0,155, K — 0,225, Ca — 0,280. Ilość katalizatora węglowego w mieszaninie reakcyjnej wynosi 5% wagowych. Przed procesem suszenia w temperaturze pokojowej na powietrzu odpadowy materiał roślinny w postaci fusów kawy lub łusek nasion słonecznika przemywa się kilkakrotnie wodą destylowaną. Podczas karbonizacji stosuje się przepływ azotu z prędkością 18 l/h. Do reaktora wprowadza się w pierwszej kolejności alfa-pinen, a później katalizator.The method of isomerization of alpha-pinene in the presence of a carbon catalyst, according to the application, at atmospheric pressure, at a temperature of 160°C, for 4 hours, with a stirring intensity of 400 rpm, is characterized in that a carbon catalyst obtained by chemical activation with a solution is used KOH and carbonization of waste plant material. Waste plant material is dried for 24 hours at room temperature in the air, then in a dryer in the temperature range of 50 - 70°C for 24 hours. The dried material is ground and mixed intensively with a KOH solution in an amount for every 10 g of material, 13 ml of KOH solution is used, the mixture is left for 3 hours at room temperature, then dried for 19 hours at 150°C, and then ground and carbonized under nitrogen at 800°C for 1 hour. The material is then cooled to room temperature under an inert gas atmosphere, ground and rinsed with water to remove the activating agent. Excess water is removed, then the carbon material obtained in this way is flooded with a 1M HCl solution in the amount of 100 ml of the solution for every 2 g of carbon material and left for 19 hours at room temperature, then it is rinsed with distilled water until neutral, and the water is evaporated. Waste plant material shall be in the form of fresh orange peels or coffee grounds or sunflower seed hulls with the following composition in % by weight: carbon catalyst obtained from orange peels: Si - 0.264, S - 0.416, Cl - 0.182, K - 0.595, Ca - 0.289, carbon catalyst from coffee grounds: Si - 0.268, S - 0.244 Cl - 0.696, K - 0.997, Ca - 0.000, carbon catalyst obtained from sunflower seed hulls: Si - 0.246, S - 0.418, Cl - 0.155, K - 0.225, Ca-0.280. The amount of carbon catalyst in the reaction mixture is 5% by weight. Before the air-drying process at room temperature, waste plant material in the form of coffee grounds or sunflower seed husks is washed several times with distilled water. During carbonization, a nitrogen flow rate of 18 l/h is used. Alpha-pinene is introduced into the reactor first, followed by the catalyst.
