| Abstract: | The pilot scale synthesis of 2 methyl 1,4 naphthoquinone(2 MNQ) from 2 methyl naphthalene with Cr 6+ as oxidant by recycle electrolytic oxidation of Cr were studied. Using filter press type electrolytic cell, Nafion 427 cation exchange mambrane, Pb Sb Sn Se alloy cathode and PbO 2/Ti anode at cell temperature 70 ℃ and current density 350 A/m 2 within 3 000 h continuous running, the results showed that the average current efficiency, average yield of 2 MNQ and average cell voltage were 73.4%, 62.5% and 3.75 V respectively, which are approximately in accordance with the laboratory results. |
