In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 657-36-3, name is 4-Trifluoromethylpiperidine, introducing its new discovery. category: piperidines
Nicotinamide synthesis of 2, 3, 6 – trichloro-pyridine process research (by machine translation)
The present invention provides a kind of nicotinamide synthesis of 2, 3, 6 – trichloro-pyridine process research, in order to nicotinamide as raw materials, the alkaline environment by adding sodium hypochlorite solution, Huffman degradation reaction, to obtain 3 – aminopyridine, in under the catalysis of a Lewis acid catalyst, and concentrated hydrochloric acid/hydrogen peroxide under the condition of chlorinated by the reaction of the 2, 6 – dichloro – 3 – aminopyridine, then in the low-temperature, under the condition of strong acid, sodium nitrite is produced by the diazonium salt solution, the final sandmaier reaction to generate the target product ? 2, 3, 6 – trichloro-pyridine, technology provided by the invention is simple in raw material, are easy and the price is cheap, the reaction condition is simple and easy operation, after treatment is simple, high yield, has good prospects for industrial development.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 657-36-3 is helpful to your research. category: piperidines
