Effects of Adding Organic Amine on the Synthesis of TS Zeolitesand Catalytic Properties

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 agentsrespectively. In this system, TBA+ canons serve as templating effects to direct the MEL structure,and then the templating agents of TBAOH, ML, or ML+TEAOH (tetraethylammonium hydroxide) could ail induce to produce TS-2 zeolites, but adding TEAOH into ML obviously enhancedthe crystallinity and framework titanium content of TS-2, and obtained a very large crystal;adding ethylenediajmine (EDA) into ML could induce to produce a few of TS-1 crystal; addingn-Dipropylamine (DPA) into ML completely induced to produce TS-1 zeolite. These zeolites werefound to show a different activity in the hydroxylation of phenol with aqueous hydrogen peroxideand the reaction of isomerizing styrene Oxide to g-phenylaldehydes.
