PROCESS OF GROWING CRYSTALLINE MICROPOROUS SOLIDS IN A FLUORIDE-CONTAINING, SUBSTANTIALLY NON-AQUEOUS GROWTH MEDIUM

摘要

Crystalline microporous solids, such as aluminosilicate zeolites or silica molecular sieves, are grown in a fluoride-containing, substantially non-aqueous medium to form crystals of the order of 0.3-3 mm in size. This growth process involves preparing a mixture containing one or more nutrients capable of forming the crystalline microporous solid; water in a controlled amount; a growth medium comprising hydrogen fluoride and a nitrogen-containing organic base; and optionally an organic solvent and/or a structure-directing agent; and thereafter heating the resulting mixture under conditions which yield the crystalline microporous solid.
