The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho - or para - hydroxylated phenyl aldehyde ( 2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide in base to form a benzenediol and a carboxylate. Overall, the carbonyl group is oxidised, whereas the H2O2 …
WebQuestion about pH of Aldehydes. Was synthesising acetaldehyde in the lab, when tested it gave a pH of 3. H2SO4 was used as a catalyst. I've been looking at various literature but … Glutaraldehyde is produced industrially by the catalytic oxidation of cyclopentene by hydrogen peroxide, which can be achieved in the presence of various tungstic acid-based heteropoly acid catalysts. This reaction essentially mimics ozonolysis. Alternatively it can be made by the Diels-Alder reaction of acrolein and vinyl ethers followed by hydrolysis.
