The process of phenol methylation in the gas phase is strongly exothermic. In order to ensure good temperature equalization in the catalyst bed, the process was carried out using a catalyst in the form of a fluidized bed - in particular, the commercial iron-chromium catalyst TZC-3/1. Synthesis of 2,6-dimethylphenol from phenol and methanol in fluidized bed of iron-chromium catalyst was carried out and the fluidization of the catalyst was examined. Stable state of fluidized bed of iron-chromium catalyst was achieved. The measured velocities allowed to determine the minimum flow of reactants, ensuring introduction of the catalyst bed in the reactor into the state of fluidization. Due to a high content of o-cresol in products of 2,6-dimethylphenol synthesis, circulation in the technological node was proposed. A series of syntheses with variable amount of o-cresol in the feed...

Iron-chromium catalyst is characterized by high activity and selectivity, that make it such an attractive bed for fluidized-bed reactor. The choice of the appropriate fraction of the catalyst is necessary to ensure a proper organization of fluid flow.

Thermodynamics and equil. of the reaction were considered. Thermal effects on the catalyst (including evapn. of the liq. reactants and heating) were detd. Incineration of gaseous products was recommended to recovery energy.
