Synthetic Route of 108-47-4, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.108-47-4, Name is 2,4-Dimethylpyridine, molecular formula is C7H9N. In a article£¬once mentioned of 108-47-4
A pyridine nitrogen oxide high-efficient, multi-phase catalytic preparation method (by machine translation)
The invention discloses a pyridine nitrogen oxide high-efficiency multi-phase catalytic preparation method. Choose the single substituted or polysubstituted pyridine or pyridine derivatives as initial material, tungsten load titanium dioxide (WO3 /TiO2 ) As catalyst, hydrogen peroxide as the oxidizing agent, at room temperature, aqueous solution obtained in the final product. The invention compared with the prior art, has the following advantages; 1, of the present invention in the oxidation method, and avoids the use of acetic acid in the method used, the requirements for apparatus is greatly reduced; 2, this invention utilizes the heterogeneous catalytic method efficient preparation of pyridine nitrogen oxide, catalyst and system through simple filtration or centrifugal can be separated, the operation is convenient; 3, the reaction utilizing tungsten load titanium dioxide as catalyst, at room temperature, aqueous solution in one-step preparation pyridine nitrogen oxides, the use of mild reaction conditions, small pollution to the environment.
