Abstract: A process of controlling heavies in a recycle catalyst stream, particularly, for use in a continuous hydroformylation process of converting an olefin with synthesis gas in the presence of a hydroformylation catalyst to form an aldehyde product stream with subsequent separation of the catalyst for recycle to the hydroformylation step. Heavies are controlled, and preferably reduced, by means of feeding a recycle gas stream, taken as a portion of an overhead stream from a condenser, back to a vaporizer wherein the aldehyde product stream is separated.

Abstract: Disclosed are surfactants of general formula R1-X in which R1 is an aliphatic C17H35- alkyl radical and X is a hydrophilic group, and the radical R1 has an average degree of branching of 2.8 to 3.7. Also disclosed are mixtures containing such surfactants as well as the use of such surfactants or the mixtures thereof for tertiary crude oil recovery.
