Crystalline aluminosilicates
Abstract
Abstract The invention relates to a method for preparing a crystalline aluminosilicate having a high silica to alumina molar ratio and an X-ray diffraction pattern substantially the same as that of ZSM-5 zeolite which method comprises mixing a source of silica, a source of alumina, a source of alkali metal, water and at least one alkanolamine according to Formula (I): ##STR1## wherein any two of R 1 , R 2 and R 3 are independently alkylol groups and the remaining one of R 1 , R 2 and R 3 is a hydrogen atom or all of R 1 , R 2 and R 3 are independently alkylol group, the alkylol groups being --CH 2 --R--OH, wherein R is --CH 2 --, --CH 2 CH 2 --, or --CH(CH 3 )--, the ratio of said source of silica to said source of alumina being at least 20:1 based on the equivalent moles of silica and alumina in said respective sources, maintaining said mixture at a temperature above about 120° C. and recovering the crystalline aluminosilicate formed.
