In 1938, Otto Roelen discovered the "Oxo" process. The Oxo process, otherwise known as the hydroformylation process, transforms olefins, which are unsaturated hydrocarbons such as propylene and ethylene, to aldehydes by adding syngas.
These aldehydes are building blocks which are either sold externally or are used internally (i.e., captive requirements) to produce Oxo Derivative products such as carboxylic acids, polyols, amines or specialty esters.
The majority of Oxo Intermediates are typically converted to Oxo Derivatives in plants adjacent to the hydroformylation units, with limited volumes of Oxo Intermediates being transported. Those Oxo Derivatives are then sold to customers who further refine such Oxo Derivatives in various application materials such as coatings, lubricants, plasticizers, additives and other materials.
