Process Economics Program Report 21D
Published: Dec-99
"Oxo" products are the generic term for chemicals manufactured from oxo-chemistry; that is, the hydroformylation of olefins by using syngas (H2/CO).
RCH=CH2 + CO + H2 ® RCH2CH2CHO
Common catalysts for the hydroformylation of olefins are Rh and Co. Rh is almost exclusively used with P-containing ligands (phosphines or phosphites). Co is used most commonly as the carbonyl (CO ligands). This report deals with a subset of oxo-productsóthe C4-C10 alcohols derived from the aldehydes produced by hydroformylation. These alcohols can be produced either by direct hydrogenation or by hydrogenating the dimers formed from aldol condensation of lower aldehydes.
Dominant technologies in the butyraldehyde-derived alcohols
field are the Rh-catalyzed technologies of Union Carbide Corporation (UCC)/Kvaerner
and Celanese. Exxonís cocatalyzed technology dominates iso-nonyl and iso-decyl
alcohol manufacture.
