ABSTRACT:
Silica gel esterification catalysts which are mechanically stable and are highly abrasion free, particularly suitable for the esterification of dimethyl terephthalate, are prepared by impregnating silica gel in solutions of aluminum, titanium, zinc and tin compounds, separating the excess solutions and drying at elevated temperatures. The catalysts are further improved by treatment with a gaseous mixture of methanol and water.
