Experiments on alkylation were carried out in a laboratory reactor with a stationary layer of catalyst at a temperature of 320-400/sup 0/. The analysis of the liquid and gaseous products was carried out by the GLC method on a LKhM-72 chromatograph; dimethyl phthalate was the liquid phase. Results of the alkylation of o-cresol by methanol was shown at different temperatures and per volume feed rates of the liquid raw material. Reaction parameters were influenced by the molar ratio of the raw material components. Results indicated a parallel-consecutive mechanism of the alkylation of o-cresol by methanol on this contact. It was shown that high activity of Ni-H-mordenite is present in the heterogeneous alkylation of o-cresol by methanol, by which 2,6- and 2,4-xylenols can be obtained in high yields.
