Abstract
Oxo synthesis or hydroformylation for the production of aldehydes and alcohols has become more important as the demand for plasticizers and detergents increases. Many processes using the homogeneous Co catalyst were well-established and have brought the big industrial success. The phosphine-modified Co catalyst used in Shell Process has led to high proportions of straight chain isomers in the product. Recently, the new oxo process for making butyraldehydes and propionaldehyde was commercialized by UCC. This technique is characterized by a phosphine-modified Rh catalyst that results in high product selectivity at low capital and operating costs.
