초록

Mannose is produced from a concentrated solution of glucose or polymers of glucose in the presence of a catalyst containing hexavalent molybdenum. Subsequent hydrogenation of the product in order to produce mannitol is also disclosed.

대표청구항 ▼

1. In a process for producing a solution containing glucose and mannose by contacting an acidic solution of glucose, oligomers of glucose, or a mixture of glucose and oligomers thereof, with a catalyst containing molybdenum in the hexavalent state at a temperature of at least about 70° C. under non-hydrogenating conditions, the improvement wherein said solution has a carbohydrate content of at least about 50 percent by weight. 2. A process according to claim 1 in which the solution is an aqueous solution. 3. A process according to claim 2, in which the pH of the solution is from about 3 to about 5. 4. A process according to claim 1 in which the solvent is a polar organic solvent. 5. A process according to claim 1 in which glucose is the starting material. 6. A process according to claim 1 in which the starting material is a carbohydrate consisting essentially of glucose and oligomers thereof. 7. A process according to claim 6 in which the starting material is cornstarch hydrolyzate. 8. A process according to claim 1 in which the reaction temperature is in the range of about 85° to about 160° C. 9. A process according to claim 1 in which the amount of catalyst is at least about 0.05% by weight, based on the weight of carbohydrate. 10. A process according to claim 1, in which the catalyst is molybdic acid. 11. A process according to claim 1, in which catalyst is an alkali metal phosphomolybdate. 12. A process according to claim 1, in which the catalyst comprises molybdenum on an ion-exchange resin. 13. A process according to claim 1 comprising the further step of removing of the molybdenum catalyst from the solution of glucose and mannose. 14. A process according to claim 1 including the further steps of hydrogenating said solution of glucose and mannose at an elevated temperature in the presence of an hydrogenation catalyst, thereby producing a solution containing sorbitol and mannitol, and recovering mannitol from said solution. 15. A process according to claim 14 in which the solution is an aqueous solution. 16. A process according to claim 14 in which the hydrogenation catalyst is a nickel catalyst. 17. A process according to claim 16 in which said solution of glucose and mannose is hydrogenated without prior removal of said molybdenum catalyst. 18. A process according to claim 14 in which the hydrogenation catalyst is a ruthenium catalyst and in which the molybdenum catalyst is separated from the solution of glucose and mannose prior to hydrogenation.
