| abstract |
The present invention relates to a process for the chemical conversion of sugars or sugar alcohols to polyols / glycols, the conversion of the sugar or sugar alcohols being carried out by hydrogenolysis in the presence of a catalyst containing at least one metal on a carbon support, the catalyst support being one with oxygen and / or phosphorus and / or boron-doped carbon carrier is used. The present invention provides a process for the chemical conversion of sugars or sugar alcohols to glycols, which enables the production of glycols with higher selectivity and reduces the formation of lactic acid as a by-product. |
