摘要：
An investigation has been made of the alkylation of phenol by methanol on modified TsVM-type zeolites. It has been established that the introduction of Mn2+, Co2+ and Ni2+ cations into the zeolite with subsequent oxidation leads to an increase in the selectivity of the catalyst with respect to para-isomer formation. The most effective catalyst is MnTsVM. The influence of the strength and nature of acid centres on the catalytic properties of specimens has been investigated.
