can. Temperatures are used which are above the dewatering temperature of the hydrosulfite in question.
One proceeds z. B. so that a slurry of azetonsulfoxylsauren) sodium with vigorous stirring in a solution or suspension of common salt and bisulfite in water

on and works at around 65 C.
Instead of common salt, other salts can be used, and other salts of acetone sulfoxylic acid can be used in place of sodium acetone.
