Abstract: Titanium-substituted silicate was synthesized by using tetrabutylammonium hydroxide (TBAOH), TS--2 mother liquor (ML), as well as ML and other organic amine as
templating agents respectively. In this system, TBA^+ cations serve as templating effects to direct the MEL structure, and then the templating agents of TBAOH, ML, or
ML+TEAOH (tetraethylammonium hydroxide) could all induce to produce TS--2 zeolites, but adding TEAOH into ML obviously enhanced the crystallinity and framework titanium
content of TS--2, and obtained a very large crystal; adding ethylenediamine (EDA) into ML could induce to produce a few of TS--1 crystal; adding n-Dipropylamine (DPA) into ML
completely induced to produce TS--1 zeolite. These zeolites were found to show a different activity in the hydroxylation of phenol with aqueous hydrogen peroxide
and the reaction of isomerizing styrene oxide to β-phenylaldehydes.
