    TS-1 titanium-silicon molecular sieve

     

    Titanium silicon molecular sieves are formed by Ti atoms partially replacing aluminum atoms in silica-aluminum molecular sieves, belonging to the ZSM-5 series zeolite molecular sieves, with MFI topological structure. The primary structural units, such as silica-oxygen tetrahedrons and titanic-oxygen tetrahedrons, are connected by oxygen Bridges to form the secondary structural units of five-membered rings, and further form a three-dimensional microporous skeleton. MFI molecular sieve has a two-dimensional pore structure, the 10-membered ring parallel to the A-axis is S-shaped, with a pore size of 0.51nm×0.55nm, and the 10-membered ring parallel to the B-axis is linear, with a pore size of 0.54nm×0.56nm.The average particle size of titanium silicon molecular sieves produced by the company is 50-60m, the minimum is close to 10m, the maximum is less than 105m, and the particle size distribution is uniform.
    Titanium silicon molecular sieves can be used as catalytic oxidation catalysts, which are widely used in oxidation reaction, epoxidation reaction and amine oximation reaction. For example, catalysts for the production of propylene oxide, catalysts for the production of cyclohexanone oxime.
