| dc.description.abstract | Hydrocarbon fractions from three road building asphalts were isolated. The first step was precipitation of the asphaltenes with n-pentane. The petrolenes were then treated with sulfuric acid, followed by chromatography of the sulfuric acid-insoluble material on Florisil. The materials isolated from the Florisil by n-pentane were fractionated by thermal diffusion. The thermal diffusion fractions were investigated by physical constant-structure correlation methods; infrared, ultraviolet, and nuclear magnetic resonance spectral methods. The results obtained by these various procedures are discussed and compared and some general conclusions are drawn concerning these hydrocarbon materials. Some hypothetical molecular structures are presented which fit the results obtained for the low molecular weight hydrocarbons present in the three asphalts. | en |
