Abstract
An organotemplate-free synthetic process for the production of a zeolite of TON framework type structure is provided. The process includes the steps of: (1) preparing a mixture comprising: (a) an alumina-coated silica; (b) a source of an alkali metal; (c) an alcohol; (d) a source of hydroxide ions; (e) seed crystals comprising a zeolitic material having a TON framework type structure; and (f) water; and (2) crystallizing the mixture obtained in step (1).
