摘要
Substituted cyclic nitrosamines, e.g., 2, 6-dimethyl-N-nitrosomorpholine and 3, 5-dimethyl-N-nitrosopiperidine are separable into their component configurational isomers by preparative hplc. Gram quantities of the individual isomers sufficient for animal testing were obtained. The identification of contaminants in commercial 2, 6-dimethylmorpholine of purported 99% is discussed. © 1979, Taylor & Francis Group, LLC. All rights reserved.
