The catalytic properties of the layered compounds—zirconium phosphate, titanium phosphate, mixed zirconium titanium phosphate, and their organically pillared derivatives—toward methanol conversion have been examined. Dimethyl ether was found to be the precursor for hydrocarbon formation. However, strong acidities of the phosphate compounds seem to enhance methane formation. The phenyl-group bridged derivatives were found to have remarkably higher catalytic activities and selectivities for the conversion of methanol to low molecular weight hydrocarbons. These pillared compounds were considered to provide pore structure for shape-selective products. Moreover, the phenyl pillars were suggested to be capable of stabilizing reaction intermediates. © 1984, American Chemical Society. All rights reserved.
