| titleOfInvention | CAPROLACTAMA PRODUCTION FROM MATERIALS CONTAINING CARBOHYDRATES |
| abstract | Processes for the conversion of glucose into caprolactam using chemo-catalytic reduction and oxidation reactions, also including processes for the conversion of glucose into caprolactam through products of polyhydroxy-amido acid and amidocaproic acid or derivatives thereof. In addition, processes that catalytically oxidize an amidopoliol in amidopolyhydroxy acid or derivatives thereof, and processes that catalytically hydroxy deoxygenate polyhydroxy amino or amido acid or derivatives thereof in an amino or amidocaproic acid product are provided. The aminocaproic acid or amidocaproic acid product can then be converted into caprolactam. Also included are products produced by said processes and products that can be produced from said products. Claim 19: A process for the preparation of a polyhydroxy amido acid product, the process comprises: reacting, in the presence of an oxidation catalyst, an amidopoliol substrate and an oxidant to convert at least a portion of the amidopoliol substrate into the acid product polyhydroxy amido, wherein the amidopoliol substrate comprises a compound of formula (1) and the polyhydroxy amido acid product comprises a compound of formula (2), wherein each X is independently, hydroxy, oxo, or acyloxy; wherein R¹ is acyl, substituted acyl, aroyl or substituted aroyl; and where R² is a salt-forming ion, hydrogen, or a lactone of the foregoing. Claim 36: A process for the preparation of an amino or amidocaproic acid product, the process comprises: reacting, in the presence of a hydrogenation catalyst and a halogen source, a polyhydroxy amino or amido acid substrate and hydrogen to convert at least a portion of the foregoing in the aminocaproic or amidocaproic acid product, wherein the polyhydroxy amino or amido acid substrate is a compound of formula (3) and the aminocaproic or amidocaproic acid product is a compound of formula (4), wherein each X it is independently hydroxyl, oxo, halo, acyloxy; wherein R¹ is acyl, substituted acyl, aroyl, substituted aroyl, or hydrogen; and where R² is a salt-forming ion, hydrogen, or a lactone of the foregoing. Claim 76: A process for the preparation of nylon 6, the process comprises: the conversion of caprolactam produced at least in part by the process of any of claims 15-18 and 61-68 in nylon 6. Claim 77: A process for the preparation of an amidocaproic acid compound from glucose of formula (5), the process comprises: a) the conversion of glucose into a cyclic polyol amido compound of formula (6), wherein R³ is acyl, substituted acyl, aroyl , or substituted aroyl; b) reacting, in the presence of an oxidation catalyst, at least a portion of the cyclic polyol amido compound of formula (6) and an oxidant to convert at least a portion of the cyclic polyol amido compound into a cyclic polyhydroxylated acid compound of formula (7) wherein R³ is as defined above and R⁴ is a salt or hydrogen forming ion; and c) reacting, in the presence of a hydrogenation catalyst and a halogen source, at least a portion of the cyclic polyhydroxy acid compound of formula (7) and hydrogen to convert at least a portion of the cyclic polyhydroxy acid compound into a compound Amidocaproic acid of formula (8), where R³ and R⁴ are as defined above. Claim 78: A process for producing caprolactam, the process comprises: a) the conversion of glucose of formula (5) into a cyclic polyol amido compound of formula (6), wherein R³ is acyl, substituted acyl, aroyl, or substituted aroyl ; b) reacting, in the presence of an oxidation catalyst, at least a portion of the cyclic polyol amido compound of formula (6) and an oxidant to convert at least a portion of the cyclic polyol amido compound into a cyclic polyhydroxylated acid compound of formula (7), wherein R³ is as defined above and R⁴ is a salt or hydrogen forming ion; c) reacting, in the presence of a hydrogenation catalyst and a halogen source, at least a portion of the cyclic polyhydroxy acid compound of formula (7) and hydrogen to convert at least a portion of the cyclic polyhydroxy acid compound into a compound amidocaproic acid of formula (8); d) Cycling at least a portion of the amidocaproic acid compound of formula (8) to produce caprolactam. |
