Acetaldehyde is obtained from an ethyl alcohol "fuel" anodically treated in a fuel cell, and the acetaldehyde (along with any evaporated, unreacted ethanol "fuel") is ultimately recovered in anhydrous or substantially anhydrous form.

Question: To Make Acetaldehyde (CH3CHO),ethanol (C2H5OH) Is Partially Oxidized Using Oxygen. Some Of The Acetaldehyde Is Partially Oxidized To Acetic Acid (CH3COOH). C2H5OH + O2 ---> CH3CHO + H2O CH3CHO + O2 ---> CH3COOH It Is Desired To Produce 120

Depending on the reaction temperature, 30-50% of the ethanol is converted per pass with a selectivity of 85-95%. The byproducts are acetic acid, formic acid, ethyl acetate, CO and CO 2. In both process modifications, the acetaldehyde is separated from the
