Abstract
Described is an olefin hydroformylation process for producing aldehydes utilizing a Pt Group IV-A organometallic catalyst mixture such as (PPh.sub.3).sub.2 PtPh-SnPh.sub.2 Cl/SnCl.sub.2. High yields of aldehydes are produced in high selectivity for the normal isomer, especially when using propylene as the olefin.
