PURPOSE:To obtain the aimed substance by reacting a mixed gas containing isobutylene, n-butene, etc., with phenol in the presence of activated clay, and either exchanging the catalyst with new one after removing the mixed gas or removing the mixed gas by passing an inert gas, and conducting rearrangement reaction to obtain the aimed substance. CONSTITUTION:A mixed gas mainly containing isobutylene and n-butene is reacted with phenol in the presence of activated clay catalyst at 10-120 deg.C (preferably 30-80 deg.C), and the raw material mixed gas dissolved in an alkylation reaction solution is removed by discharging or blowing an inert gas, exchanging the used catalyst with new activated clay to carry out rearrangement reaction or the raw mixed gas dissolved in the alkylation reaction solution is removed by blowing the inert gas to carry out rearrangement reaction while continuing blowing the inert gas to obtain the titled substance. The rearrangement reaction is carried out at 50-200 deg.C (preferably 80-130 deg.C) for 1-5hr. EFFECT:Production of p- and o-sec-butylphenol, which is not readily separated and purified, can be suppressed. USE:A raw material for plasticizer, resin, etc. |
