摘要： A process for the recovery of glycerol comprises contacting an aqueous feed composition that comprises water, glycerol, and at least one contaminant with a solvent extractant comprising at least one C5-C8 alkanol, optionally in admixture with at least one alkane, to form a first mixture, and separating the first mixture into a first solvent phase and a first aqueous phase. The first solvent phase comprises a majority (more than 50 wt %) of the solvent extractant and a majority of the glycerol that was present in the aqueous feed composition. The weight ratio in the first solvent phase of glycerol to a contaminant present is greater than the weight ratio of glycerol to the contaminant in the aqueous feed composition. The first aqueous phase comprises a majority of the water from the aqueous feed composition and at least some of the contaminant from the aqueous feed composition.

摘要： In the dehydrochlorination of 3,4-dichlorobutene-1 to give chloroprene in a two-phase mixture of water and an alcohol, a bleed stream may be taken from the organic phase to prevent high boiling impurities accumulating. Problems in recovering the alcohol from the bleed are overcome by extracting the bleed with water at a volume ratio of water and organic phase brought into contact at the first extraction step of not less than 15:1, or if the organic phase is substantially free of chloroprene, not less than 6:1.

摘要： 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.
