A study of the sulfuric acid catalyzed reaction between phenol and isobutylene

[摘要] The sulfuric acid catalyzed reaction between isobutylene and phenol vas carried out in a continuous stirred tank reactor at atmospheric pressure.The sulfuric acid to phenol mole ratio in the 14quid feed rate was 0.0206 throughout the experiment.The isobutylene feed rate to phenol feed rata ratio was maintained at 0.537 +/- 0.052 moles/mole tbroughout the experiment. The reaction was carried out at temperatures of 192°F, 230°F, and 276°F and at holdup times of from eight to thirty minutes based on the total liquid feed rate.The composition of the reaction product was determined with the aid of a gas-liquid chromatographic column.Under the conditions of this investigation no reaction rates or specific rate constants could be determined as the composition of the reaction mixture did not change greatly with the holdup times investigated.
