发明名称 Method for making 2,6-xylenol
摘要 A method for making 2,6-xylenol is described. One embodiment of the method comprises: preparing a magnesium-based solid catalyst composition by dry-blending basic magnesium carbonate with at least one filler; forming the catalyst composition into a suitable catalyst-shape; calcining the shaped catalyst at a temperature in the range of about 350° C. to about 550° C.; and reacting phenol and methanol in the presence of the catalyst, to form 2,6-xylenol. The level of chlorides in the magnesium carbonate is less than about 250 ppm, and the level of calcium in the magnesium carbonate is less than about 2,500 ppm.
