摘要： Processes are disclosed for the oxidation of alkanes such as, for example, propane, to form unsaturated carboxylic aldehydes and acids such as, for example, acrolein and acrylic acid. The processes utilize oxygen and recycle alkanes, e.g., propane, to the aldehyde reactor. The presence of the alkene in the alkene-to-aldehyde reaction can enhance the efficiency of the processes.

摘要： This invention relates in part to processes for producing one or more substituted or unsubstituted epsilon caprolactams, e.g., epsilon caprolactam, which comprises: (a) subjecting one or more substituted or unsubstituted alkadienes to hydroxycarbonylation in the presence of a hydroxycarbonylation catalyst, e.g., a metal-organophosphorus ligand complex catalyst, and neutralization with a base to produce one or more substituted or unsubstituted pentenoic acid salts; (b) subjecting said one or more substituted or unsubstituted pentenoic acid salts to hydroformylation in the presence of a hydroformylation catalyst, e.g., a metal-organophosphorus ligand complex catalyst, to produce one or more substituted or unsubstituted formylvaleric acid salts and/or one or more substituted or unsubstituted epsilon caprolactam precursors; and (c) subjecting said one or more substituted or unsubstituted formylvaleric acid salts and/or said one or more substituted or unsubstituted epsilon caprolactam precursors to reductive amination in the presence of a reductive amination catalyst and cyclization optionally in the presence of a cyclization catalyst to produce said one or more substituted or unsubstituted epsilon caprolactams. This invention also relates in part to reaction mixtures containing one or more substituted or unsubstituted epsilon caprolactams as the principal product(s) of reaction.
