Information
has glosseng: 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) and a hydrogen atom to a carbon-carbon double bond. This process has undergone 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, the resulting aldehydes are hydrogenated to alcohols that 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.

Norwegian
has glossnor: Hydroformylering, oksosyntese, er en viktig kjemisk prosessindustri for produksjon av aldehyder fra alkener. Denne kjemisk reaksjon innebærer addisjon av en formylgruppe (CHO) og et hydrogen atom til en karbon-karbon dobbelbinding.

Portuguese
has glosspor: A hidroformilação (chamada também "processo oxo" ou "oxo síntese") é a reação que resulta em um aldeído, a partir de um alqueno, monóxido de carbono e hidrogênio. O processo consiste na ruptura da própria ligação por ataque nucleófilo ao átomo de carbono do monóxido e pelo acréscimo de um átomo de hidrogênio. A reação em geral é conduzida a alta pressão (10 - 100 atm) em presença de catalisador metálico (em geral ródio, rutênio, cobalto, platina) ou seus complexos. A temperatura de reação se situa em torno de 40 a 300°C.

Swedish
has glossswe: 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 butanal och butanon.
