2,3,5,6-Tetrachloropyridine Chemical Properties,Uses,Production

Uses

2,3,5,6-Tetrachloropyridine is used as a chemical intermediate in the production of chlorpyrifos and triclopyr.

Synthesis

2,3,5,6-Tetrachloropyridine is synthesised in three steps by chemical reaction using 2,3,4,5,6-pentachloropyridine as a raw material. The specific synthesis steps are as follows:
Step (1): 2 parts of pentachloropyridine was dissolved in 200 parts of ethanol at 40 ℃ until 0.6 part of metallic manganese powder was added after the raw material was completely dissolved; 1.3 parts of ammonium acetate, 5 parts of water and 10 parts of ethanol were mixed Uniform dropping, dropping time of 2h; After completion of the dropwise addition, the reaction solution was stirred for 4 hours.
Step (2): add ammonia to adjust the pH value of 8~9, heated to 65 , through 3L / min air 1h reaction was oxidized.
Step (3): Oxidation liquid filtration: The resulting solid was filtered and separated by washing with 20 parts of toluene. Ethanol washed twice, washed twice, after dryingproduct. Products tested by the magnetic content of manganese oxide products, the specific surface area of 53m2 / g, Mn content of 70.90%, CaO content0.0012%, K content 0.0005%, Na content 0.0025%, S content 0.0070%. The XRD pattern of manganese tetroxide and the comparison with the standard map is Mn3O44. Figure 5 (a) and (b) are scanning electron micrographs. It can be seen that the product is a hollow spherical structure. (C) and (d) are transmission electron micrographs, and the hollow structure can be seen and the product is from 10 to 25 nm Grain composition. The filtrate was filtered and the organic solution of the solution of manganese tetrachloride was combined and evaporated to recover the toluene solvent. Then, 10 parts of 5% dilute hydrochloric acid was added at a temperature of 65 ℃ and stirred for 1 h to obtain 2,3,5,6-tetrachloropyridine ; The yield was 99.5%.
