Abstract:
The invention discloses a synthesis method of 4 amino 3,6 dichloropyridine 2 carboxylic acid, aiming at solving the existing electrolysis, acidification and crystallization to prepare 4 amino 3,6 dichloropyridine 2 formic acid, the appearance of the product is brown red, which seriously affects the quality of the product. According to the invention, the electrolytic cell is divided into a separate anode area and a cathode area by selecting some special cationic membranes, so that the effect of electrolytic dechlorination is not affected, but also to avoid the surface of the anode oxidation reaction to generate oxygen (or highly active free radicals), and the cathode generated 4 amino 3,6 dichloropyridine 2 formate contact, thus, brown-red impurities are not generated, and the process and cost of post-treatment are greatly simplified.

Abstract:
4-amino-3, 6-dichloropicolinic acid (4-N-3,5,6-TCP,CAS:150114-71-9), it is a kind of plant growth regulator that mimics the effect of natural auxin, and it is a synthetic hormone herbicide. It is mainly used to control the growth range of broad-leaved weeds in pasture, plantation and non-crop areas [1,2,3]. Mainly by inducing plants to produce a partial response, which leads to plant growth arrest and necrosis [4,5]. View all>
