How is acetic acid prepared from acetylene?
Advertisements
उत्तर
Acetylene is first converted to acetaldehyde by passing through 40% H2SO4 at 60°C in the presence of 1% HgSO4.
\[\ce{C2H2 + H2O ->[H2SO4(dil.)][HgSO4] CH3CHO}\]
The acetaldehyde is then oxidised to acetic acid in the presence of the catalyst manganous acetate at 70°C.
\[\ce{\underset{Acetaldehyde}{CH3CHO} + O2 ->[\Delta][Catalyst] \underset{Acetic acid}{2CH3COOH}}\]
