  • Process for producing mixtures rich in 1,6-GPS or 1,1-GPM
    Patent number: 6414138
    Abstract: The invention relates to a process for producing mixtures selectively enriched with either 1,1-GPM and 1,6-GPS from hydrogenated isomaltulose. The process involves dissolving hydrogenated isomaltulose at an elevated temperature, and subjecting the resulting solution to one or more cooling steps, wherein each cooling step utilizes a predetermined cooling rate over a predetermined temperature range.
    Type: Grant

  • Process for the hydrogenation of sugars
    Patent number: 6103894
    Abstract: The invention relates to a process for the hydrogenation of sugars and sugar mixtures from the group consisting of isomaltulose, trehalulose, maltulose, leucrose and lactulose to sugar alcohols or sugar alcohol mixtures wherein the sugars or sugar mixtures are hydrogenated with hydrogen in an aqueous solution at elevated temperature and elevated pressure, using a nickel-containing catalyst attached to a carrier.
    Type: Grant
    Filed: January 9, 1998
    Date of Patent: August 15, 2000
    Assignee: Sudzucker Aktiengesellschaft
    Inventors: Hanspeter Degelmann, Jorg Kowalczyk, Markwart Kunz, Matthias Schuttenhelm
  • Process for the hydrogenation of sugars using a shell catalyst
    Patent number: 5936081
    Abstract: The invention relates to a process for the hydrogenation of sugars and sugar mixtures to sugar alcohols or sugar alcohol mixtures wherein the sugars or sugar mixtures are hydrogenated with hydrogen in an aqueous solution at elevated temperature and elevated pressure by using a shell catalyst comprising a mixture of a pure Raney metal and a Raney metal alloy and wherein the shell catalyst has an essentially catalytically inactive core functioning as a carrier and a catalytically active shell.
