CATALYST FOR PHENOL ALKYLATION WITH METHANOL TO ORTHOCRESOL OR TO 2,6-XYLENOL

摘要

Catalyst for phenol alkylation with methanol to orthocresol or to 2,6-xylenol containing metal oxides and silica, characterized in that it contains magnesium, iron, chromium, silicon, antimony, and vanadium oxides, whereas their molar ratios range from 100:10:0.03:0.003:0.002:0.003 to 100:400:24:24:16:16, preferably from 100:25:0.07:0.25:0.025:0.025 to 100:75:4:4:2:2.
