OXIDATION OF 1, 1-DIALKYLHYDRAZINES—CHROMATOGRAPHIC SEPARATION AND ULTRAVIOLET ANALYSIS OF SOME TETRAALKYLTETRAZENES

摘要

A method for the gas-liquid chromatographic separation of mixtures of tetraalkltetrazenes at 70℃on a column containing polyethylene glycol as the stationary phase is described. The effluent distribution and resolution of several tetraalkltetrazenes is determined by ultraviolet absorption analysis in both absolute ethanol and basic aqueous solution. Factors affecting the quantitative aspects of the chromatographic separation and recovery of the tetraalkltetrazenes are considered in detail.
