Abstract: SO2 reversibly bound to aldehyde components is reviewed. Splitting off of SO2 at higher temps. under pressure in acid and alk. medium was studied. In the alk. medium it depends especially not only on pH but also on the hydroxide-in the order of decreasing degree of dissocn.: NaOH(KOH) > Ca(OH)2 > Ba(OH)2 > NH3.
