Fig. 3From: Preparation of ursodeoxycholic acid from 7-ketone lithocholic acid by stereoselective electroreductionCyclic voltammograms of 0.04 M 7K-LCA in the solvent with 0.08 M KBr at different scan rates: (a) 10 mV s−1, (b) 50 mV s−1, and (c) 100 mV s−1, T = 65 °C. The solvent was 130 ml of co-solvent (MeOH/H2O = 9.83/1, volume ratio)Back to article page
