Production of the 3,6- jikuroro -2- trichlororo methyl pyridine with the vapor phase chlorination of 6- kuroro -2- trichlororo methyl pyridine

摘要

With heating chlorinating 6- kuroro -2- trichlororo methyl pyridine (i) in the vapor phase, being the method of obtaining 5,6- jikuroro -2- trichlororo methyl pyridine (ii) and the chlorination blend which contains 3,6- jikuroro -2- trichlororo methyl pyridine (iii) and being improved, the aforementioned improvement, making contact 6- kuroro -2- trichlororo methyl pyridine (i) with chlorine under existing of the L type zeolite catalyst, the method of including the fact that you obtain the blend which contains 3,6- jikuroro -2- trichlororo methyl pyridine (iii) mainly.
