References of 2-hydroxypropanoic acid
Title: DL-Lactic Acid
CAS Registry Number: 598-82-3
CAS Name: 2-Hydroxypropanoic acid
Synonyms: racemic lactic acid; ordinary lactic acid; a-hydroxypropionic acid; Milchs?ure (German)
Trademarks: Lactovagan (Schwartzhaupt); Tonsillosan (L?sung) (Spitzner)
Molecular Formula: C3H6O3
Molecular Weight: 90.08
Percent Composition: C 40.00%, H 6.71%, O 53.28%
Literature References: Occurs in sour milk as a result of lactic acid bacteria; also found in molasses due to partial conversion of sugars, in apples and other fruits, tomato juice, beer, wines, opium, ergot, foxglove, and several higher plants, especially during germination. Lactic acid is prepd technically by "lactic acid fermentation" of carbohydrates such as glucose, sucrose, lactose with Bacillus acidi lacti or related organisms such as Lactobacillus delbrueckii, L. bulgaricus etc. The fermentation is carried out at relatively high temps. Produced commercially by fermentation of whey, cornstarch, potatoes, molasses. Review on the production of lactic acid by fermentation: S. C. Prescott, C. G. Dunn, Industrial Microbiology (McGraw-Hill, New York, 3rd ed., 1959) pp 304-331. Chem prepns from acetaldehyde and CO in dil H2SO4 at 130-200° and 900 atm: Loder, US 2265945 (1938 to du Pont); by hydrolysis of hexoses with NaOH: Lock, US 2382889 (1943). Prepn of crystalline lactic acid: Borsook et al., J. Biol. Chem. 102, 449 (1933). Toxicity data: Smyth et al., J. Ind. Hyg. Toxicol. 23, 259 (1941). Comprehensive description: F. J. Al-Shammary et al., Anal. Profiles Drug Subs. Excip. 22, 263-316 (1993).
