An acetone:citral mixture was prepared (molar ratio 12:1). Then, 1 g of the particular catalyst was weighed into a glass inlet provided with a stirrer fish and topped up with 30 ml of the respective citral:acetone solution. Here, the empty weight and also the weight of the filled glass inlet was determined. The filled glass inlet was then placed in the autoclave and the latter was screwed tight. The autoclave was provided with the heating muff and the thermocouple and the experiment temperature was established using the Eurotherm controller. The experiment time was 3 hours for all of the experiments. The time measurement started upon reaching the experiment temperature. When the experiment was complete, the autoclave was cooled in an ice bath and opened. The gas inlet was weighed again and the reaction mixture was centrifuged. A GC sample with dodecane as standard was yielded from the now clear reaction solution. The catalyst was freed from citral remains, dried and characterized with the help of X-ray analysis. Some catalysts were used a second time in order to test their activity.
