Patent ID: 7368603

Claim:
A method for separating a saturated organic compound bearing at least one functional group from a mixture which comprises this saturated organic compound containing at least one functional group and also one or more other organic compounds, which comprises i) mixing a silver-ion-loaded ion exchanger with the mixture at a temperature which is below the boiling point of the mixture, ii) then removing the supernatant and iii) detaching the ion-exchanger-bound, saturated organic compound having at least one functional group from the ion exchanger, wherein the saturated organic compound containing at least one functional group which is bound to the ion exchanger is detached from the ion exchanger using a solvent; the saturated organic compound bearing a functional group contains at least one group which is selected from ═O, —OH, —C(O)OH, —C(O)H, —COOR, —C—O—C— and —C—O—R—, where R is an organic group, and the ion exchanger has a water content of less than 10 ppm.
