Abstract: Experiments were conducted on carbon adsorption from solutions of phenol, o-cresol, and 2,4-dichlorophenol in various combinations. The equilibrium data were found in general agreement with predictions based on the ideal adsorbed solution (IAS) theory. The kinetic measurements suggest that the adsorption process can be described by the film-surface diffusion (FSD) model. By using the algorithms developed in Part I and based on the rate and equilibrium data obtained from single adsorbate adsorption measurements, concentration histories of the individual adsorbate of carbon adsorption from solutions containing phenol, o-cresol and 2,4-dichlorophenol can be predicted with sufficient accuracy.

TL;DR: In this paper, an o-methylated phenolic compound using a catalytic vapor-phase reaction of phenol and/or o-cresol with methanol using a catalyst containing vanadium oxide and iron oxide calcined at a specific temperature and supported on a specific amount of silica.
Abstract: PURPOSE:To obtain a phenolic compound having a methyl group at the o-position economically, by the catalytic vapor-phase reaction of the titled compound with methanol using a catalyst containing vanadium oxide and iron oxide calcined at a specific temperature and supported on a specific amount of silica. CONSTITUTION:An o-methylated phenolic compound useful as a raw material of polyphenylene oxide, agricultural chemicals, pharmaceuticals, etc., is prepared by the catalytic vapor-phase reaction of phenol and/or o-cresol with methanol using a catalyst containing vanadium oxide and iron oxide calcined at >=550 deg.C, preferably 650-900 deg.C and supported on 10-80wt%, preferably 20-80wt% of silica. The objective o-methylated phenolic compound can be prepared economically in an industrial scale, because the catalyst has excellent activity and selectivity, and sufficiently high strength to endure the long-term reaction even in the absence of water in the reaction system.
