Reaction between phenol and 130–190°C fraction of liquid pyrolysis products in the presence of catalyst KU-23 in a continuous plant

The results of the alkylation of phenol by 130–190°C fraction of the liquid pyrolysis products in the presence of a catalyst KU-23 of H-form carried out in a continuous plant were reported. Optimal conditions for the synthesis of p -alkyl phenol were found. It was shown that under the optimal mode a yield of target alkyl phenol was 69.7% of theory and selectivity, 93.3%. p -Alkyl phenolamine resin tested as an antioxidant engine oil at high temperatures was synthesized on the basis of p -alkyl phenol and hexamine.
