Abstract
Method of reducing the concentration of sulfur and/or a sulfur-containing compound in a biochemically prepared organic compound by bringing the respective organic compound into contact with an adsorbent. Ethanol which has a particular specification and can be prepared by the abovementioned method, and its use as solvent, disinfectant, as component in pharmaceutical or cosmetic products or in foodstuffs or in cleaners, as feed in steam reforming processes for the synthesis of hydrogen or in fuel cells, or as building block in chemical synthesis.

A method of reducing the concentration of sulfur and/or a compound comprising sulfur in a biochemically prepared organic compound selected from an alcohol, ether or a carboxylic acid, the method comprising, contacting the prepared organic compound into contact with an adsorbent in the liquid phase.
Ethanol produced from agricultural products by fermentation comprising:
- a content of sulfur and/or organic compounds comprising sulfur from 0 to 0.1 ppm by weight (calculated as S),
- a content of C3-4-alkanols from 1 to 5000 ppm by weight,
- a methanol content from 1 to 5000 ppm by weight,
- an ethyl acetate content from 1 to 5000 ppm by weight, and
- a 3-methyl-1-butanol content from 1 to 5000 ppm by weight.
