Abstract
Description
technical field
[0001] The invention relates to a modification method of a titanium silicalite material. Background technique
[0002] Titanium silicalite is a new type of heteroatom zeolite developed in the early 1980s. At present, TS-1 with MFI structure, TS-2 with MEL structure, MCM-22 with MWW structure and TS-48 with larger pore structure have been synthesized. Among them, the titanium silicalite TS-1 developed and synthesized by Italy Enichem Company is a new type of titanium silicalite with excellent catalytic selective oxidation performance formed by introducing transition metal element titanium into the zeolite framework with ZSM-5 structure. TS-1 not only has the catalytic oxidation effect of titanium, but also has the shape-selective effect and excellent stability of ZSM-5 zeolite. Using this titanium silicalite as a catalyst can catalyze various types of organic oxidation reactions, such as epoxidation of alkenes, partial oxidation of alkanes, oxidation of alco...
