Resourceful treatment method of picloram solid residues

The invention relates to a picloram solid residue resourceful treatment method which comprises the following steps: a) carrying out decarboxylation reaction on picloram solid residues, performing filtering, taking filtrate, and separating out solid; b) sequentially carrying out diazotization and chlorination reaction on the solid obtained in the step a), separating out the solid, performing filtering, taking a filter cake, and performing separating to obtain 2, 3, 4, 5-tetrachloropyridine; c) subjecting the 2, 3, 4, 5-tetrachloropyridine obtained in the step b) to a dechlorination reaction soas to obtain 2, 3, 5-trichloropyridine and/or 2, 5-dichloropyridine. According to the resourceful treatment method provided by the invention, the picloram solid residues can be converted into 2, 3, 5-trichloropyridine products with good market demand prospects and relatively high economic values, and further efficient utilization of the picloram solid residues is realized.

DESTRUCTIVE CHLORINATION OF 3,4,5-TRICHLORO-2-(TRICHLOROMETHYL)PYRIDINE

The extensive destructive chlorination of 3,4,5-trichloro-2-(trichloromethyl)pyridine proceeds by both thermal (160-245 deg C) and photochemical pathways.Perchloropyridine, perchloropicoline, and carbon tetrachloride are formed.The chlorinated derivatives of pyridine are formed by the loss of the CCl3 group with its subsequent replacement by a chlorine atom.
