The investigation of phenol wish cyclodimer isoprene interaction reaction in the presence of KU-23 catalyst in continuously acting settlement
Ch.K.RasulovThe results of investigation reaction of phenol with dipren, dipentene and fraction of cyclodimer isoprene by application CU-23 as a catalyst in H-form is given in the article. By the aim of finding optimal condition providing maximal going out steam of cycloalkylphenols were studied the influence of temperature, mol correlation of outcome components and voluminal speed for going out and selectivity cycloalkylphenols. There arranged that optimal conditions for interaction reaction of phenol with dipren is 1000C temperature mol correlation phenol to dipren equal 1:1 and volumianal speed is 0.5 hour. In these conditions going out of aimed product is 71.5% from theory, but selectivity 92.6% according to cycloalkylphenol. The analogous results obtained for reaction alkylation phenol with dipentene and fraction in 160-1800C cyclodimer isoprene. In optimal regime going out of to-cycloalkylphenol on the basis of dipentene and fractions cyclodimer is 68.4 and 70.6%, but selectivity is 90.3 and 90.7% accordingly. There was determined physico-chemical indexes and cleanliness of synthesized stream-cycloalkylphenols. The structures of products determined via spectral methods and by the chromatographic analysis.
