The industrial processes vary depending on the chain length of the olefin to be hydroformylated, the catalyst metal and ligands, and the recovery of the catalyst. The original Ruhrchemie process produced propanal from ethene and syngas using cobalt tetracarbonyl hydride. Today, industrial processes based on cobalt catalysts are mainly used for the production of medium- to long-chain o… WebA process to produce 1-octene and 1-decene includes (a) separating a composition containing an oligomer product – which contains from 15 to 80 mol % C6 olefins, from 20 to 80 mol % C8 olefins, and from 5 to 20 mol % C10+ olefins – into a first oligomer composition containing C6 alkanes and at least 85 mol % C6 olefins (e.g., 1-hexene), a …
