Abstract

A process for the prepn. of a zeolite, pref. of SiO2:Al2O3 ratio above 10 esp. above 15, comprises reacting >=1 source of silica, >=1 source of alumina, >=1 alkali as defined below and >=1 alcohol. By alkali is meants a hydroxide or salt of acid such as alumina or silicic acid which is not stronger than Li, Na, K, quaternary ammonium or phosphonium carbonates. A novel zeolite, freshly prepd. has an SiO2, Al2O3 ratio >10 and is free from quat. ammonium or phosphonium cpds.
