<sod>'''Hydroformylation''', also known as '''oxo synthesis''' or '''oxo process''', is an important [[homogeneous catalysis|homogeneously catalyzed]] industrial process for the production of [[aldehyde]]s from [[alkene]]s.<ref>Ojima, I.; Tsai, C.-Y.; Tzamarioudaki, M.; Bonafoux, D. ''[[Org. React.]]'' '''2000''', ''56'', 1. {{doi|10.1002/0471264180.or056.01}}</ref> This chemical reaction entails the addition of a [[formyl]] group (CHO) and a [[hydrogen]] atom to a carbon-carbon double bond. This process has undergone continuous growth since its invention in 1938: Production capacity reached 6.6×10<sup>6</sup> tons in 1995. It is important because the resulting aldehydes are easily converted into many secondary products. For example, the resulting aldehydes are hydrogenated to [[alcohols]] that are converted to [[plasticizer]]s or [[detergent]]s. Hydroformylation is also used in [[speciality chemicals]], relevant to the [[organic synthesis]] of [[fragrance]]s 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]].<eod>
