In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Safety of 2,4-Dimethylpyridine, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 108-47-4, name is 2,4-Dimethylpyridine. In an article£¬Which mentioned a new discovery about 108-47-4
Lewis acid/base adducts of TiCl4 and methylpyridines
By the reaction of 2-methyl-and 2,6-dimethylpyridine the first neutral TiCl4L complexes (L = single bonded ligand) could be synthesized. The structures have been determined by single crystal X-ray methods. The best description of the molecular structure is a distorted trigonal bipyramid with the nitrogen base occupying an equatorial position. With 2,4-dimethylpyridine, a 1:2 adduct is formed, where the nitrogen bases are in frans-positions of a TiCl4N2-octahedron, as also confirmed by an X-ray analysis.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 108-47-4, help many people in the next few years.Safety of 2,4-Dimethylpyridine
