The Separation Of Optical Isomers By Gas Chromatography, Donald Ellis Carpenter

Masters Theses

"The purpose of this investigation was to study the separation of optical isomers by gas chromatography. An optically inactive solid support was coated with an optically active substrate. Racemic compounds were used as samples. The optically active packing materials tried were d-tartaric acid, d-diethyl tartrate, sucrose, d-camphoric acid, d-camphor-10-sulfonic acid, α -methyl-D-glucoside and L-(α)-glutamic acid.

Racemic compounds that were tried included 2-butanol, 3-methyl- 2-butanol, 2-methyl-1-butanol, 2-octanol, 2-bromooctane, 2-methoxy-octane, methyl-2-bromobutyrate, and 3-methylhexane.

It was found that racemic compounds could be separated by using an optically active material for packing in the gas chromatographic columns. Racemic 2-butanol, 3-methyl-2-butanol, and 2-methyl-1- butanol were …
