Abstract
Alkylation reactions of 130-190°C fraction of liquid products of pyrolysis with the presence of KH-30 catalyst impregnated with hydrochloric acid of phenol were studied. As a result, the effect of various parameters - reaction temperature, duration, molar ratios of initial components and the amount of catalyst - on the yield and selectivity of the target product was investigated. It was determined that the yield of para-arylalkylphenol is 78.6%, and the selectivity is 94.3%. Although more than 100 years have passed since the study of alkylation reactions of phenol, the preparation of alkylphenols and their various derivatives has not lost its relevance even today. Alkylphenol-based chemical compounds are finding new effective areas of use: they are insecticides, pesticides, etc. against agricultural pests. they are used as a ligand for catalytic precursors used in the production, oligo- and polymerization of olefins, and as an extractant in the purification of oil fractions from aromatic hydrocarbons. Keywords: phenol, fraction 130-190°C, catalyst, arylalkylation, para-arylalkylphenol.
