The synthesis method is to send SO2 into a cold saturated aqueous potassium carbonate solution until no CO2 is produced and the solution becomes acidic. During operation, it should be cooled sufficiently and attention should be paid to air isolation. By adding approximately the same amount of ethanol to the concentrated aqueous solution prepared in the above operation, a large amount of potassium bisulfite crystals can be precipitated. The crystals were filtered and washed with ethanol, then placed on filter paper and dried in a stream of nitrogen.Send Inquiry
