    Hydroformylation means the introduction of

    Solutions

    Hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes from alkenes. This chemical reaction entails the net addition of a formyl group (CHO) and a hydrogen atom to a carbon-carbon double bond.

    Example: H2 + CO + CH3CH=CH2 → CH3CH2CH2CHO
