UNIT SHEET WEIGHTS OF ASPHALT FRACTIONS DETERMINED BY STRUCTURAL ANALYSIS

TWO ASPHALT SHORT RESIDUES, ONE KUWAIT AND THE OTHER ARABIAN, WERE FRACTIONATED BY GEL PERMEATION CHROMATOGRAPHY AND THE FRACTIONS OBTAINED WERE EXAMINED BY NUCLEAR MAGNETIC RESONANCE AND INFRARED SPECTROMETRY. FRACTION MEAN MOLECULAR WEIGHT AND ELEMENTAL COMPOSITION WERE ALSO MEASURED. THE PROPORTIONS OF THE DIFFERENT TYPES OF CARBON LINKAGE PRESENT WERE DETERMINED BY THE SOLUTION OF A SERIES OF SIMULTANEOUS EQUATIONS DERIVED FROM THE EXPERIMENTAL DATA. A UNIT SHEET WEIGHT CALCULATED FROM THE MOLECULAR STRUCTURAL ANALYSIS WAS FOUND TO BE EQUIVALENT TO THE WEIGHT CALCULATED BY NMR, THUS ELIMINATING THE ESTIMATION OF VALUES OF THE NONAROMATIC CARBON TO HYDROGEN RATIO. THE RELATIVE ERROR WAS 7.6%. /AUTHOR/
