hydroformylation

Hydroformylation, also known as oxo synthesis, is an important industrial process for the production of aldehydes from alkenes. This chemical reaction entails the addition of a formyl group (CHO) group and a hydrogen atom to a carbon-carbon double bond. This process has witnessed continuous growth since its invention in the 1930’s: production capacity reached 6.6×106 tons in 1995. It is important because the resulting aldehydes are easily converted into many secondary products. For example, in the Shell higher olefin process (SHOP), the resulting aldehydes are hydrogenated to alcohols, which are converted to detergents. Hydroformylation is also used in specialty chemicals, relevant to the organic synthesis of fragrances and natural products. The development of hydroformylation, which originated within the German coal-based industry, is considered one of the premier achievements of 20th century industrial chemistry.

Oxo-syntes är en kemisk reaktion där olefiner (alkaner) reagerar med syntesgas över en katalysator, bestående av metallerna rodium eller kobolt, som är i komplex med organiskt material, t.ex. trifenylfosfin. Aldehyd fås som produkter. Syntesgasen måste vara extremt ren. Av eten + syntesgas fås propanal (propanaldehyd). Om istället propen används, fås 1-butanal och 2-butanal.
