ABSTRACT:
A molecular sieving metallosilicate is disclosed which comprises a complex represented in terms of mole ratios of oxides by the formula: ##STR1## wherein A is an ammonium, alkyl ammonium, alkyl phosphonium or alkyl arsonium ion; D is an alkali or alkaline earth metal ion or a mixture of two or more thereof; E is selected from the group consisting of Al, B, Mo, W, Fe, or a mixture of two or more thereof; M is a tetravalent metal selected from the Lanthanide or Actinide series; a is a number ranging from zero to about 25; b is a number ranging from zero to about 1.5; c is a number ranging from zero to about 0.3; d is a number ranging from about 20 to about 500; e is a number ranging from zero to about 200. The X-ray diffraction pattern for these metallosilicates indicates a ZSM-5 like crystalline structure. A method for making these metallosilicates, and a method for dehydrating and reforming methanol using these metallosilicates are disclosed.
