Aldehyde production method and principle

1. Take acetylene as an example Acetylene and two water addition, there will be two hydroxyl groups hanging on the same carbon, remove one hydroxyl group and the other hydroxyl group on the hydrogen, combined with water, carbon and oxygen on the half-bonds are connected to form a carbon and oxygen double bond, that is, acetaldehyde

2. Take ethylene as an example Ethylene and a reaction with an O2, ethylene and O2 double bond are disconnected, the two half-bonds on the carbon and the two half-bonds on the oxygen are connected to form a carbon-oxygen double bond, that is, formaldehyde

3. Forming a carbon-oxygen double bond, which is formaldehyde

3. Alcohol reacts with oxygen (CuO, Ag2O)
