| titleOfInvention | Method for purifying dimethyl sulfone by electrodialysis |
| abstract | The invention provides a method for purifying dimethyl sulfone by electrodialysis, which comprises the steps of constructing an electrodialysis system, wherein the electrodialysis system comprises a power supply, and a cathode plate, an electrodialysis module and an anode plate which are sequentially arranged; the electrodialysis membrane group is an anion exchange membrane- (cation exchange membrane-anion exchange membrane) arranged in sequence N Wherein N is an integer of 1 to 30; a cathode chamber is formed between the cathode plate and the adjacent anion exchange membrane, and an anode chamber is formed between the anode plate and the adjacent anion exchange membrane; electrically connecting the cathode of the power supply to the cathode plate and the anode of the power supply to the anode plate; circularly supplying electrode solution to the cathode chamber and the anode chamber, circularly supplying dimethyl sulfone solution containing electrolyte impurities to the desalting chamber, and circularly supplying electrolyte solution to the concentrating chamber; the method is environment-friendly and energy-savingHigh efficiency, can prepare high-purity dimethyl sulfone products and has important significance. |
