Catalyst preforming rates during hydroformylation may decrease in the presence of carbonates. Carbonate mitigation methods may comprise treating a hydroformylation reaction product with an aqueous carboxylic acid under oxidizing conditions to form a deactivated catalyst aqueous solution having a pH of about 4 or less, reducing the hydroformylation reaction product to form a reduced reaction product, conveying a gas stream through the reduced reaction product to strip carbon dioxide therefrom, contacting caustic aqueous solution with the stripped reduced reaction product to form partially spent caustic aqueous solution, combining at least a portion of the partially spent caustic aqueous solution with the deactivated catalyst aqueous solution to form a combined aqueous mixture sufficiently acidic to decompose carbonate, and extracting a Group 9 transition metal carboxylate from the combined aqueous mixture into an organic phase.

Devices, systems, and methods for forming furan based surfactants by reactive distillation are disclosed herein. Various embodiments can provide a consolidated reaction process that uses reactive distillation to synthesize oleo-furan surfactant molecules and intermediates by combining reaction and separation steps into a single reaction unit or a number of connected reaction units. The single reaction unit or a number of connected reaction units can include a catalyst bed and act to separate reaction side products at opposing ends of the unit or units.

A hydrocarbon compound and carbon monoxide are reacted in the presence of either a supported chromium (VI) catalyst or a supported chromium (II) catalyst, optionally with UV-visible light irradiation and/or exposure to an oxidizing atmosphere, followed by removing a reaction product containing an alcohol compound and/or a carbonyl compound from the respective chromium catalyst. Often, the reaction product contains one or more ketone and/or aldehyde compounds.
