3, 4, 5, 6-tetrachloropyridine method for the preparation of formic acid

The invention provides a preparation method of 3,4,5,6-tetrachloropyridine-2-carboxylic acid. The method comprises the following steps: with waste residue generated in production of picloram or waste obtained after further purification of the waste residues generated in production of the picloram as raw material, adding nitrite for diazotization by the effects of strong acid and an inert diluent; adding a chlorine substituting agent for chlorination reaction to prepare the 3,4,5,6-tetrachloropyridine-2-carboxylic acid. A small amount of other isomerides generated during an ammonolysis process of tetrachloropyridine-2-carboxylic acid during circular processing and treatment of the method can be used for transforming non-pesticide components in the waste residues into raw production materials with practical values, so that the emission of the waste residues is reduced as far as possible. The prepared 3,4,5,6-tetrachloropyridine-2-carboxylic acid is higher than 95% in effective content and can satisfy the requirements on raw materials for industrial production of the picloram.
