| | (S,S)-2,3-Butanediol Usage And Synthesis |
| Description | 2, 3-Butanediol, which is very important for a variety of chemical feedstocks and liquid fuels, can be derived from the bioconversion of natural resources1-2. It may be used in the production of antifreeze solvents, extraction solvents, butadiene, polymers, polyurethane and diacetyl and may also be used as a fuel1, 2. It can be used as a precursor in the manufacture of a range of chemical products, various plastics and pesticides, including the solvents methyl ethyl ketone (MEK), gamma-butyrolactone (GBL), and 1, 3-butadiene3. Methyl ethyl ketone can be used as a liquid fuel additive. Many other derivatives for potential uses as antifreeze agent (levo-form of 2,3 BDL), solvents, and plastic can also be prepared from 2.3-BDL. Furthermore, it can be added as a flavoring agent in food products when converted to a diacetyl by dehydrogenation2. Nowadays, it has been more and more applied of microbial fermentation for the production of 2.3-BDL2,4.
