    摘要： A method of preparing an aromatic phosphine monosulfonate in zwitterionic form, such as dicyclohexylphenylphosphine monosulfonate zwitterion, involving contacting an aromatic phosphine with a sulfonating agent to provide a reaction mixture containing aromatic phosphine monosulfonate in acid form and unconverted sulfonating agent; quenching or removing substantially all of the unconverted sulfonating agent; partially neutralizing the aromatic phosphine monosulfonate in acid form to phase separate aromatic phosphine monosulfonate in zwitterionic form as a solid or neat liquid layer; and collecting the zwitterion as a solid or neat liquid. The zwitterion may be neutralized to form the corresponding aromatic phosphine monosulfonate metal salt, which is useful in preparing catalysts for hydroformylation processes.

    摘要： Oximes can be converted to the corresponding amides by contacting the oximes with a non-zeolitic molecular sieve, which has in its calcined form an adsorption of isobutane of at least about 2 percent by weight of the non-zeolitic molecular sieve at a partial pressure of 500 torr and a temperature of 20.degree. C. The process is especially useful for the conversion of cyclohexanone oxime to caprolactam. The non-zeolitic molecular sieves can achieve improved conversion rates and selectivities as compared with conventional zeolite catalysts for the reaction.

    摘要： Aldehydes can be condensed with ketones or aldehydes to produce higher aldehydes or ketones by contacting the materials to be condensed with a nonzeolitic molecular sieve. The condensation may be carried out in the presence of hydrogen to give as product a saturated aldehyde or ketone. The ketone and/or aldehyde may be generated in situ by dehydrogenation of an alcohol, and the hydrogen thus liberated used to effect hydrogenation of the immediate unsaturated product of the condensation, thereby producing as the final product a saturated aldehyde or ketone. The non-zeolitic molecular sieves can achieve improved conversion rates and selectivities as compared with conventional catalysts for the reaction.

    摘要： Two ketone molecules (which can be the same or different) can be condensed together in the presence of hydrogen to produce a higher ketone by contacting the materials to be condensed with a hydrogenation catalyst and with a non-zeolitic molecular sieve, which has in its calcined form an adsorption of isobutane of at least about 2 percent by weight of the non-zeolitic molecular sieve at a partial pressure of 500 torr and a temperature of 20.degree. C. One or both ketones may be generated in situ by dehydrogenation of an alcohol. The non-zeolitic molecular sieves can achieve improved conversions and selectivities as compared with most conventional catalysts for the reaction.

    摘要： A non-aqueous hydroformylation process with liquid catalyst recycle involving a hydroformylation step and one or more stages of phase separation to recover a high molecular weight aldehyde product with efficient recovery of rhodium catalyst. The process includes a hydroformylation step to prepare a non-aqueous hydroformylation reaction product composition comprising one or more aldehyde products, one or more conjugated polyolefins, a rhodium-organophosphorus ligand complex, free organophosphorus ligand, and an organic solubilizing agent for said complex and said free ligand, and thereafter one or more stages of phase separation using added water under a carbon monoxide gas, hydrogen gas, or a mixture thereof. The process requires a specific range of total pressure for the hydroformylation, a specific range of total pressure for at least one of the separation stages, and a minimum sum of the total pressure of the hydroformylation step and the total pressure of the separation stage containing said gas.
