  The invention relates to a process for the production of 5-formylvaleric acid and adipic acid or esters thereof from an isomeric mixture of pentenoic acid or esters thereof said mixture comprising at least 4-pentenoic acid or esters thereof, and further comprising 3-pentenoic acid and/or 2-pentenoic acid or esters thereof, theprocess comprising: (a) subjecting the isomeric mixture of pentenoic acid to a hydroformylation reaction comprising a hydroformylation catalyst which is non-isomerizing towards the pentenoic acid or esters thereof to obtain a mixture comprising 5-formylvaleric acid or esters thereof and further comprising 3-pentenoic acid and/or 2-pentenoic acid, or esters thereof; (b) separating the 3-pentenoic acid and/or 2-pentenoic acid, or esters thereof from the 5-formylvaleric acid or esters thereof; (c) subjecting the separated pentenoic acids or esters thereof to a carbonylation reaction comprising an isomerizing carbonylation catalyst to obtain adipic acid or esters thereof; (d) optionally isolating the adipic acid or ester thereof; and (e) optionally isolating the separated 5-formylvaleric acid or esters thereof. The process allows for efficient production of two different intermediates for producing polyamide using a single process, with good selectivity, little waste, in an economically efficient fashion. The process is very suitable to use an isomeric pentenoic acid mixture obtained from valerolactone, and can be used to produce renewable polyamide intermediates using a single process.

  本发明涉及一种从戊烯酸异构体混合物或其酯中生产5-甲酰基戊二酸和己二酸或其酯的工艺，所述混合物包括至少4-戊烯酸或其酯，并进一步包括3-戊烯酸和/或2-戊烯酸或其酯，该工艺包括：(a)将戊烯酸异构体混合物经过羰基化催化剂催化的羰基化反应，该催化剂对戊烯酸或其酯不进行异构化，以得到包括5-甲酰基戊二酸或其酯和进一步包括3-戊烯酸和/或2-戊烯酸或其酯的混合物；(b)将3-戊烯酸和/或2-戊烯酸或其酯与5-甲酰基戊二酸或其酯分离；(c)将分离的戊烯酸或其酯经过异构化羰基化催化剂催化的羰基化反应，以得到己二酸或其酯；(d)可选择性地分离己二酸或其酯；以及(e)可选择性地分离分离的5-甲酰基戊二酸或其酯。该工艺允许使用单一工艺高效生产用于制造聚酰胺的两种不同的中间体，具有良好的选择性，少量废料，经济高效。该工艺非常适合使用从缩酮酸获得的异构戊烯酸混合物，并可用于使用单一工艺生产可再生聚酰胺中间体。
