| 摘要 |
This invention is for a process for the ortho-alkalation of phenols in the presence of a magnesium oxide alkylation catalyst. The process comprises the vapor phase reaction of a non-ortho-substituted phenol with an alcohol in the presence of an alkylation catalyst and is characterized by the introduction of water vapor into the reaction system. The water vapor effects continuous regeneration thereby substantially increasing catalyst life before regeneration is required. This is an important advantage as it increases the period of reactor operation before shut down is required, thereby making the overall process more economical.
