Abstract
Various alkanes,-enes and-ynes of molecular weights below C10 are rapidly separated by gassolid adsorption chromatography on untreated activated alumina. Solid silver nitrate coated on alumina removes alkenes and alkynes through oxidative degradation. Silver-nitrate concentration and column temperature markedly affect olefin removal. At about 300C some of the C8 and higher molecular weight saturated hydrocarbons are destroyed. Conditions for this subtractive chromatography are detailed, and the fate of unsaturated hydrocarbons is explained.
