[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.

[Chemical Properties]

SLIGHTLY YELLOW OILY LIQUID
[Uses]

(S,S)-2,3-Butanediol is the (S,S)-isomer of 2,3-Butanediol (B690020), a naturally occurring compound found in cocoa butter.
[Definition]

ChEBI: The (S,S) diastereoisomer of butane-2,3-diol.
[General Description]

L-(+)-2,3-Butanediol is a stereoisomer of 2,3-Butanediol (2,3-BD). 2,3-BD may be used in the production of antifreeze solvents, extraction solvents, butadiene, polymers, polyurethane and diacetyl and may also be used as a fuel.
[Purification Methods]

Purify it by fractional distillation. The bis-(4-nitrobenzoate) has m 141-142o and [] (-) or (+) 52o (c 4 CHCl3). [Ghirardelli & Lucas J Am Chem Soc 79 734 1957, Rubin et al. J Am Chem Soc 74 425 1952, Neish Can J Res 27 6 1949, Neish & Ledingham Can J Res 27 694 1949, Beilstein 1 IV 2524-2525.]
