摘要： Processes are disclosed for the conversion of a carbohydrate source to hexamethylenediamine (HMDA) and to intermediates useful for the production of hexamethylenediamine and other industrial chemicals. HMDA is produced by direct reduction of a furfural substrate to 1,6-hexanediol in the presence of hydrogen and a heterogeneous reduction catalyst comprising Pt or by indirect reduction of a furfural substrate to 1,6-hexanediol wherein 1,2,6-hexanetriol is produced by reduction of the furfural substrate in the presence of hydrogen and a catalyst comprising Pt and 1,2,6-hexanediol is then converted by hydro genation in the presence of a catalyst comprising Pt to 1,6 hexanediol, each process then proceding to the production of HMDA by known routes, such as amination of the 1,6 hexanediol. Catalysts useful for the direct and indirect production of 1,6- hexanediol are also disclosed.

摘要： Disclosed herein are processes for the chemocatalytic conversion of a pentose source to a glutaric acid product of formula II, wherein R1 is defined in the specification. The process comprises reacting a C5-backbone substrate of formula I and hydrogen gas in the presence of a hydrodeoxygenation catalyst and a halogen source. In one embodiment the hydrodeoxygenation catalyst comprises a first metal selected from Ru, Rh, Pd, Pt, and combinations thereof and a second metal selected from Mo, Ru, Rh, Pd, Ir, Pt, and Au. Also disclosed are processes comprising the catalytic oxidation of pentose to pentaric acid in which the pH of the reaction mixture is no greater than 7 and catalytic hydrodeoxygenation of pentaric acid or derivatives thereof to a glutaric acid product.

摘要： Disclosed are catalysts comprised of platinum and rhodium on a support selected from the group of zirconia stabilized (doped) zirconia zirconia metal oxide composites and mixtures thereof wherein the outer surfaces of the support are selected from the group of zirconia stabilized zirconia and mixtures thereof. The catalysts are generally useful for the selective hydrodeoxygenation of carboxylic acids containing at least one additional hydroxyl group along the backbone thereof. More particularly the catalysts are supported catalysts comprising platinum and rhodium wherein the molar ratio of platinum to rhodium is in the range of about 3:1 to about 1:2. The average pore diameter of the catalyst supports is in the range of from about 5 nm to about 70 nm and the surface area is in the range of from about 15 m/g to about 200 m/g. Also disclosed are methods for the hydrodeoxygenation of carboxylic acids mono and/or di lactones thereof having at least one hydroxyl group on the backbone thereof to corresponding acids where the backbone hydroxyl group has been reduced in the presence of the catalyst. Further disclosed is a process of producing an adipic acid product at a yield of at least about 80%.
