Abstract: High purity synthetic zeolites having open frameworks, such as offretite, uncontaminated with detectable traces of other zeolites, can be synthesized by the hydrothermal reaction of a silica source, alumina source, sodium hydroxide and/or potassium hydroxide in the presence of a zeolite nucleation slurry synthesized from a mixture of a silica source, alumina source, sodium hydroxide and/or potassium hydroxide and an organic template agent. The preferred organic template agents are the quaternary compounds wherein the central element is one from Group 5A of the Periodic Table and various conjugated aromatic compounds. The zeolite synthesis mixture itself does not contain any organic ion template agent. With this organic template agent not being required, the nucleation slurry is used to promote crystallization of the synthesis mixture to the open framework type of zeolite.
