Ts-1 catalyst

Titanium silicon molecular sieve TS-1 Ammoxidation catalyst has a three-dimensional pore structure is composed of two sets of ten membered ring channel and a set of ninemembered ring channel interleaving composition, molar group hasbecome (0.001 ~ 0.2) TiO2: SiO2. Ammoxidation catalyst is Ti atoms replace part of aluminum atoms insilicon aluminium molecular sieve and into, which belongs to ZSM-5 series zeolite molecular sieve, with the MFI structure, composed ofsilicon oxygen tetrahedron and titanium oxygen tetrahedron primarystructural unit, connecting through the oxygen bridge, constitute asecondary structure unit of five membered rings, and further to form a three-dimensional porous skeleton, pore structure with two-dimensional MFI molecular sieve, parallel to the a axis of the ten membered ring is in a S shape, aperture of 0.51nm * 0.55nm, ten membered ring and linearly parallel to the b axis direction,aperture of 0.54nm * 0.56nm. Use Ammoxidation catalyst is produced by our company, the averagediameter of 50-60m, minimum close to 10m, the maximum is less than 105m, uniform particle size distribution Ammoxidation catalyst can be used as catalytic oxidation catalyst,is widely used in oxidation, epoxidation and amidoximation reaction.For example, a catalyst for the production of propylene oxide,catalyst for the production of cyclohexanone oxime.
