Method Extracts Enantiomers.

Chiral Technologies, Inc. (730 Springdale Ave., Exton, PA; Tel 610/594-2100; Fax: 610/594-2325) has developed a method for separating an enantiomeric mixture of chiral amino acids into its enantiomeric parts. In the process, the chiral mixture is subjected to chromatography on a chiral polysaccharide stationary phase. The mobile phase consist of a liquid lower alkanol - a carboxylic acid soluble in the lower alkanol. The liquid phase may contain a liquid hydrocarbon as well. The method is suitable for separating chiral amino acids, including alanine, phenylalanine, serine, valine, theonine, and DOPA, among others. Although the molecules are insoluble in typical mobile phases, …
