FIELD: industrial inorganic synthesis.
SUBSTANCE: crystalline aluminosilicate zeolite identified as UZM-4M is prepared by treatment of zeolite UZM-4M with fluorosilicate salt to form zeolite having empiric formula M1a n+Al1-ExSiyOz, wherein M1 represents alkali metal, alkali-earth metal, hydronium ion, or ammonium ion, E represents element selected from group consisting of gallium, iron, boron, indium, or mixture thereof, and having Si/Al ratio from 1.5 to 10. Proposed is used as catalytic component in hydrocarbon conversion processes.
EFFECT: enlarged assortment of zeolite catalysts.
