Abstract
The paper deals with the results of research into phenol cycloalkenylation with 3- vinylcyclohexene in the presence of modified zeolite-containing catalyst Zeokar-2M on the laboratory batch unit and aminomethylation of the obtained p-(cyclohexene-3-yl-ethyl) phenol with formaldehyde and aniline. The temperature effects, reaction time, molar ratio of phenol to vinylcyclohexene (VCH) and amount of the catalyst on the yield and selectivity of phenol cycloalkenylation with VCH were studied to define optimal conditions that ensure the maximum yield of the target product. The obtained products were tested as antioxidants for diesel fuel and showed satisfactory results, which indicates the effectiveness of their use.
