DIFFERENCE IN THE CATALYTIC ACTIVITIES FOR THE CONVERSION OF METHANOL BETWEEN TRIVALENT AND TETRAVALENT Ti ION EXCHANGED FORMS OF LAYERED SILICATE

Article abstract of DOI:10.1246/cl.1983.1849

The catalytic activities of Ti ion exchanged forms of layered silicate minerals are completely different by the ionic valencies.Methanol was dehydrated to dimethyl ether and hydrocarbons over Ti(IV) forms of the minerals, whereas dehydrogenated to methyl formate and methylal over Ti(III) forms of the minerals.It is of particular interest that acetone is formed from methanol over Ti(III) form of fluoro tetrasilicic mica (Ti(III)-TSM).
