“…When the reaction between phenol and TBA was performed in vapor phase, higher phenol conversion was obtained and the main products was 4-TBP, regardless the zeolite topology [146][147][148][149][150][151]. Amount of 2,4-DTBP was also regularly obtained.…”

Isobutene (IB), the most reactive molecule in the C4 raffinate, is a raw material of great industrial significance. It is extensively used in the manufacturing process of rubber, fuel additives, fine chemicals, agricultural chemicals, plastics and antioxidants. Heterogeneous catalysts and particularly zeolites are playing a major role in these applications. The aim of this review is to examine the relevant processes involving IB as reagent and zeolites as acid catalysts. The following reactions are successively covered: Prins condensation, IB dimerization, IB-methanol/ethanol etherification, IB-glycerol etherification, IB amination, and phenol tert-butylation. While reasonably comprehensive and broad, the present survey is not necessarily exhaustive. The mechanistic aspects of the titled reactions, the role of zeolite catalysts and their topology/active sites on the product selectivity are mainly explored.

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.
