Abstract
Disclosed is a process for separating unreacted olefins, paraffins, aldehydes and alcohols from the catalyst and heavy ends from the hydroformylation process by using thin film distillation. In this process, the crude oxo product is metered into a thin film evaporator wherein the distillate containing olefins, paraffins, aldehydes and alcohols is rapidly separated by a continuous wiping action from the residue which contains the catalyst complex and the heavy ends. The various products are fractionated while the residue is directly recycled.
