| Abstract: | The stannous methanesulfonate is synthesized by diaphragm electrolysis method. The current density,the acidity of cathode and anode,the stabilizer and the conditions of concentration were systematically investigated. The current density = 1. 8 A·dm-2,the acidity of cathode =180 g/L,the acidity of anode = 180 g /L and the temperature = 80℃ are identified as the best technical parameters. |
