Abstract of the Disclosure High pressure methylation of 2,6-xylenol to produce 2,3,6-trimethylphenol is accomplished by maintaining the methanol/2,6-xylenol feed at temperature and pressures sufficient to keep the feed liquid in a reactor head then forcing the feed through orifices, expanding the feed into a mixed vapor liquid phase, the feed after expansion being in the range of reaction conditions of pressure and temperature while in the presence of the catalyst where the reaction takes place. The process avoids the current problems of uneven feed mixtures and catalyst tube plugging.
