  • Patent number: 11414376
    Abstract: Processes are disclosed for the synthesis of an ?-amino acid or ?-amino acid derivative, from a starting compound or substrate having a carbonyl functional group (C?O), with hydroxy-substituted carbon atoms at alpha (?) and beta (?) positions, relative to the carbonyl functional group. According a particular embodiment, an ?-, ?-dihydroxy carboxylic acid or carboxylate is dehydrated to form a dicarbonyl intermediate by transformation of the ?-hydroxy group to a second carbonyl group (adjacent a carbonyl group of the starting compound) and removal of the ?-hydroxy group. The dicarbonyl intermediate is optionally cracked to form a second, in this case cracked, dicarbonyl intermediate having fewer carbon atoms relative to the dicarbonyl intermediate but preserving the first and second carbonyl groups. Either or both of the dicarbonyl intermediate and the cracked dicarbonyl intermediate may be aminated to convert the second carbonyl group to an amino (—NH2) group, for producing the corresponding ?-amino acid(s).

  • Publication number: 20220064136
    Abstract: Selective hydrogenation processes are disclosed that can upgrade impure feeds, such as those obtained from biomass and containing a number of small (e.g., 2-6 carbon atom) molecules having aldehyde and/or ketone carbon atoms. For example, whereas glycolaldehyde and its methylated derivative, hydroxyacetone (acetol) are both high value intermediates for certain downstream processing reactions, they are normally recovered in a condensate from pyrolysis of carbohydrates (e.g., aldose-containing sugars) together with glyoxal and its methylated derivative, pyruvaldehyde. The selective hydrogenation of these compounds bearing two carbonyl carbon atoms, without over-hydrogenation to ethylene glycol and propylene glycol, can increase the concentration of the desired intermediates. These beneficial effects of selective hydrogenation may be achieved through the use of a hydrogenation catalyst comprising noble metals such as Ru and Pt.

  • Publication number: 20210309604
    Abstract: Improvements in catalyst systems and associated processes for the conversion of glycolaldehyde to monoethanolamine are disclosed. The catalyst systems exhibit improved selectivity to this desired product and consequently reduced selectivity to byproducts such as diethanolamine and ethylene glycol. These beneficial effects are achieved through the use of acids, and particularly Lewis acids, as co-catalysts of the reductive amination reaction, in conjunction with a hydrogenation catalyst.

  • Patent number: 10519124
    Abstract: Disclosed herein are methods for synthesizing 1,2,5,6-hexanetetrol (HTO), 1,6 hexanediol (HDO) and other reduced polyols from C5 and C6 sugar alcohols or R glycosides. The methods include contacting the sugar alcohol or R-glycoside with a copper catalyst, most desirably a Raney copper catalyst with hydrogen for a time, temperature and pressure sufficient to form reduced polyols having 2 to 3 fewer hydoxy groups than the starting material. When the starting compound is a C6 sugar alcohol such as sorbitol or R-glycoside of a C6 sugar such as methyl glucoside, the predominant product is HTO. The same catalyst can be used to further reduce the HTO to HDO.
