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.
