Separation of hydrocarbons of high molecular weight by adsorption on silica gel

Data are presented on the separation of different types of hydrocarbons of high molecular weight by adsorption on silica gel. A sharp separation of 5-{7tetrahydronaphth yl)-docosane from 5-{2-decahydronaphthyl)-docosane, and ndotriacontane from 1-{p-diphenyl)-octadecane was obtained. Some separation of 1-{p-diphenyl)-octadecane from 5-{7-tetrahydronaphthyl)-docosane was found, but the separation was not as sharp as with the two preceding mixtures. No separation of a mixture of n-dotriacontane and 5-{2-decahydronaphthyl)-docosane was found.
