《Electrocatalytic dechlorination of chloropicolinic acid mixtures by using palladium-modified metal cathodes in aqueous solutions》 was written by Ma, Hongxing; Xu, Yinghua; Ding, Xufen; Liu, Qi; Ma, Chun-An. Formula: C6H2Cl3NO2 And the article was included in Electrochimica Acta on August 20 ,2016. The article conveys some information:

In China, chloropicolinic acid (ClPA) mixtures comprising 3,5,6-trichloropicolinic acid, 3,6-dichloropicolinic acid (3,6-D), 3-ClPA, and 6-ClPA are discharged as organic wastes at a rate of ∼300 tons per yr. The authors developed an aqueous phase electrocatalytic hydrogenation (ECH) system based on Pd catalyst to dechlorinate the ClPA mixtures into picolinic acid (PA) at room temperature Firstly, the authors evaluated the influence of cathode support and Pd loading on the catalytic performance of cathodes, as well as the effects of operating parameters on the intermediate product selectivity and dechlorination efficiency of the ECH process with 3,6-D as the target compound Secondly, the authors analyzed the ECH dechlorination mechanism of 3,6-D with regard to the surface condition of cathode and catholyte pH, and the rate-limiting step of the dechlorination process is also discussed. Finally, the authors assessed the practicability of the ECH system to dechlorinate the ClPA mixtures into PA by using a plate-and-frame cell. Pd/Ni foam cathodes with Pd loading of 2.25-3.6 mg cm-2 exhibited the optimum ECH dechlorination performance, and the basic aqueous solution and high 3,6-D concentration favored the ECH process. The ClPA mixtures with 47 g L-1 concentration (the total concentration of ClPAs was ∼250 mM) can be selectively dechlorinated into PA with 99% yield, 76.3% current efficiency, and 2.47 kW h kg-1 PA specific elec. energy consumption at a c.d. of 208 A m-2 in a 1.25 M NaOH aqueous solution In addition to this study using 3,5,6-Trichloropicolinic acid, there are many other studies that have used 3,5,6-Trichloropicolinic acid(cas: 40360-44-9Formula: C6H2Cl3NO2) was used in this study.
