CONTEXT

Aldehydes and especially acetaldehyde are precursors widely-used for the synthesis of numerous intermediates such as acetic acid, peracetic acid, acetic anhydride, etc… Current acetaldehyde synthesis depends on fossil resources and is usually operated through ethylene direct oxidation, acetylene hydration or even C3/C4 alkane gas phase oxidation.

However, these methods do not always give good results in terms of yield and have the disadvantage of producing environmentally unfriendly carbon dioxide (CO₂).
