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