    • This invention relates in part to processes for producing one or more substituted or unsubstituted epsilon caprolactones and/or hydrates and/or esters thereof which comprise subjecting one or more substituted or unsubstituted penten-1-ols to carbonylation in the presence of a carbonylation catalyst, e.g., a metal-organophosphorus ligand complex catalyst, to produce said one or more substituted or unsubstituted epsilon caprolactones and/or hydrates and/or esters thereof. The substituted and unsubstituted epsilon caprolactones and/or hydrates and/or esters thereof produced by the processes of this invention can undergo further reaction(s) to afford desired derivatives thereof, e.g., epsilon caprolactam. This invention also relates in part to reaction mixtures containing one or more substituted or unsubstituted epsilon caprolactones and/or hydrates and/or esters thereof as principal product(s) of reaction.
    • 本发明部分涉及制备一种或多种取代或未取代的ε-己内酯和/或其水合物和/或其酯的方法,其包括在羰基化催化剂存在下使一种或多种取代或未取代的戊烯-1-醇进行羰基化, 例如金属 - 有机磷配体络合物催化剂,以产生所述一种或多种取代或未取代的ε己内酯和/或其水合物和/或其酯。 通过本发明方法制备的取代和未取代的ε-己内酯和/或其水合物和/或酯可进一步反应以提供其所需的衍生物,例如ε己内酰胺。 本发明还部分涉及含有一种或多种取代或未取代的ε-己内酯和/或其水合物和/或其酯作为主要反应产物的反应混合物。
