Abstract
Abstract A crystalline metal organosilicate having the composition, in its anhydrous state, as follows: 0.9 ± 0.2 [xR.sub.2 O + (1-x) M.sub.2/n O]: <.005 Al.sub.2 O.sub.3 :>1SiO 2 where M is a metal, other than a metal of Group IIIA, n is the valence of said metal, R is an alkyl ammonium radical and x is a number greater than 0 but not exceeding 1, said organosilicate being characterized by a specified X-ray diffraction pattern. Said organosilicate is prepared by digesting a reaction mixture comprising (R 4 N) 2 O, sodium oxide, an oxide of a metal other than a metal of group IIIA, an oxide of silicon and water. The crystalline organosilicates are useful as adsorbents and in their catalytically active form as catalysts for organic compound conversion.
