This invention relates to a process for separating one or more organophosphorus ligand degradation products, one or more reaction byproducts and one or more products from a continuously generated reaction product fluid comprising one or more unreacted reactants, a metal-organophosphorus ligand complex catalyst, optionally free organophosphorus ligand, said one or more organophosphorus ligand degradation products, said one or more reaction byproducts, said one or more products, one or more nonpolar solvents and one or more polar solvents by phase separation wherein (i) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more products is expressed by a partition coefficient ratio Ef1which is a value greater than about 2. 5, (ii) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more organophosphorus ligand degradation products is expressed by a partition coefficient ratio Ef2 which is a value greater than about 2. 5, and (iii) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more reaction byproducts is expressed by a partition coefficient ratio Ef3 which is a value greater than about 2. 5.

This invention relates to a process for separating one or more organophosphorus ligand degradation products, one or more reaction byproducts and one or more formylester products from a reaction product fluid comprising one or more unreacted unsaturated ester reactants, a metal-organophoshorus ligand complex catalyst, optionally free organophosphorus ligand, said one or more organophosphorus ligand degradation products, said one or more reaction byproducts, said one or more products, a nonpolar solvent and a polar solvent by phase separation wherein (i) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more products is expressed by a partition coefficient ratio Ef1 which is a value greater than about 2. 5 (ii) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more organophosphorus ligand degradation products is expressed by a partition coefficient ratio Ef2 which is a value greater than about 2. 5, and (iii) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more reaction byproducts is expressed by a partition coefficient ratio Ef3 which is a value greater than about 2. 5.

568454

A method for recovering a transition metal, e. g. , rhodium, from a non-polar organic solution containing non-polar organic solvent-soluble and polar solvent-insoluble coordination complex of the transition metal and a non-polar organic solvent-soluble and polar solvent-insoluble ligand, e. g. , an organophosphorus ligand, by contacting the non-polar organic solution with a polar solution of an ionic organophosphine ligand, the transition metal then can be transferred back into a non-polar solution for reuse. In one embodiment rhodium is rendered amenable for back-extraction by treating the polar solution with a suitable conditioning reagent.

This invention relates to a process for producing one or more organic acids in high purity which process comprises (i) oxidizing in a liquid oxidation reactor one or more organic liquids with essentially pure oxygen or oxygen-enriched air containing at least about 50% oxygen, at a temperature sufficiently stable to prevent cycling of reaction rate, to produce a crude reaction product fluid, and (ii) refining said crude reaction product fluid to give said one or more organic acids in high purity. The oxidation temperature is preferably controlled to within about ±3° C. of a target temperature. The organic acids described herein is useful in a variety of applications, such as intermediates in the manufacture of chemical compounds, pharmaceutical manufacture and the like.

A method of producing substantially pure dialkyl maleate by separating monoalkyl maleate from dialkyl maleate in a short residence time distillation zone while minimizing reversion of the monoalkyl maleate to alkanol and maleic anhydride and without having to neutralize the monoalkyl maleate.
