ISOLATION OF ANHYDRO SUGAR ALCOHOLS BY SELECTIVE ADSORBENTS |
| 摘要 |
A method is disclosed for recovering anhydrosugar alcohols from a mixture comprising closely related compounds, such as sugar alcohols. In the method the mixture is contacted with an adsorbent, whereby the anhydrosugar alcohols are selectively adsorbed. The anhydrosugar alcohols can be recovered by desorption from the adsorbent, using a desorbing solvent. |

1. A method for recovering anhydrosugar alcohols from a mixture further containing sugar alcohols, said method comprising the steps of:
a. Contacting the mixture with an adsorbent, whereby the anhydrosugar alcohols are selectively adsorbed; b. Separating the adsorbent from the mixture; c. Desorbing anhydrosugar alcohols from the adsorbent by contacting the adsorbent with a desorbing solvent. |
