Abstract
An improved allyl alcohol hydroformylation process and catalyst are disclosed. The process uses a catalyst system comprising a Group VIII metal carbonyl complex catalyst, a trisubstituted phosphine, a neutral Group VIII(a) metal complex cocatalyst, and optionally, a diphosphinoalkane. The process uniquely gives an enhanced linear:branched aldehyde product ratio.
