| Abstract: | 3,6-Dichloropicolinic acid(3,6-DCP)as a highly active and low-toxicity compound is mainly used as herbicide,pesticide and plant growth regulator.Synthesis methods of 3,6-DCP are summarized as follows:(1)Due to high cost,hydrolysis of 3,6-dichloro-2-(trichloromethyl)pyridine or 2-cyano-3,6-dichloropyridine to prepare 3,6-DCP(in spite of the method is good in reaction selectivity)is not suitable for commercial production.(2)The synthesis method of 3,6-DCP by hydrolysis-reduction dechlorination of 2-cyano-3,4,... |
