    摘要： A process for the minimization of phosphonium ion ligand degradation products formed during reaction of a polyunsaturated olefin or an unconjugated functionalized olefin in the presence of a transition metal-triorganophosphine ligand complex catalyst to form as a product, by-product, or intermediate product a conjugated functionalized olefin having a carbon-carbon double bond conjugated to an a-electronwithdrawing group, such as, an a,β-unsaturated aldehyde, ketone, ester, acid, or nitrile. The minimization process involves conducting the reaction under selected conditions of conversion, temperature, pressure, or a combination thereof; and/or by selecting a triorganophosphine ligand with a specified steric and/or electronic property. Further, a process for reversion of phosphonium ion ligand degradation product(s) back to useful triorganophosphine ligand(s), the reversion involving treating a reaction product fluid containing the degradation product(s) with an inert gas, hydrogen, synthesis gas, or a mixture thereof under conditions sufficient to regenerate the triorganophosphine ligand(s).

    摘要： The present invention relates to a process for producing an optically active aldehyde (first aldehyde) containing a reduced amount of the corresponding enantiomeric aldehyde (second aldehyde) which process comprises: (1) providing an initial solution containing a non-eutectic mixture of the first aldehyde and the second aldehyde, which mixture has a composition in the compositional region where only the first aldehyde crystallizes when its solubility limit in the solution is exceeded, and (2) maintaining the solution at a temperature above the eutectic temperature of the mixture and under conditions such that the solubility limit of the first aldehyde is exceeded so as to form a crystalline first aldehyde containing relatively less of the second aldehyde than was present in the initial solution.
