Application In Synthesis of 3,5,6-Trichloropicolinic acidOn March 30, 2010, Ma, Chun An; Li, Mei Chao; Liu, Yan Na; Xu, Ying Hua published an article in Electrochimica Acta. The article was 《In situ FTIR studies on the electrochemical hydrodechlorination of 3,4,5,6-tetrachloropicolinic acid on Ag cathode》. The article mentions the following:
The electrochem. hydrodechlorination reaction from starting material 3,4,5,6-tetrachloropicolinic acid (3,4,5,6-TCP) to the end product 3,6-dichloropicolinic acid (3,6-DCP) was studied by cyclic voltammetry and in situ FTIR spectroscopy (in situ FTIR). Compared with Cu and glassy C, Ag cathode showed a high electrocatalytic activity for the irreversible reduction process of 3,4,5,6-TCP in NaOH aqueous solution In situ FTIR results suggested that electrochem. hydrodechlorination took place in the 4- or 5-position of 3,4,5,6-TCP on Ag cathode after receiving an electron to get mixed trichloropicolinic acid free radical, which could receive another electron and give 3,5,6-trichloropicolinic acid (3,5,6-TCP) and 3,4,6-trichloropicolinic acid (3,4,6-TCP) at the potential more pos. than -1000 mV afterwards. Finally, 3,5,6-TCP and 3,4,6-TCP were further dechlorinated to produce 3,6-dichloropicolinic acid (3,6-DCP) at the potential more neg. than -1000 mV. Further studies of preparative electrolysis experiments by constant current electrolysis were carried out. The results were in good agreement with those from in situ FTIR studies. In the experimental materials used by the author, we found 3,5,6-Trichloropicolinic acid(cas: 40360-44-9Application In Synthesis of 3,5,6-Trichloropicolinic acid)
3,5,6-Trichloropicolinic acid(cas: 40360-44-9) belongs to pyridine. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. As ligands, solvents, and catalysts they facilitate reactions; thus descriptions of these new ligands and their applications abound each year.Application In Synthesis of 3,5,6-Trichloropicolinic acid
