INVERSE GAS-LIQUID CHROMATOGRAPHIC STUDIES OF ASPHALT- COMPARISON WITH ANALYSES BY FRACTIONATION

RESULTS OF ANALYSIS OF ASPHALTS BY INVERSE GASLIQUID CHROMATOGRAPHY (GLC) HAVE BEEN COMPARED WITH RESULTS OF ANALYSES BY THE KLEINSCHMIDT CHROMATOGRAPHIC FRACTIONATION AND THE ROSTLER AND STERNBERG SULFURIC ACID PRECIPITATION PROCEDURES. RELATIONSHIPS BETWEEN THE TWO FRACTIONATION TECHNIQUES ARE INDICATED. THE COMBINED ASPHALTENE AND ASPHALTIC RESIN CONTENT FROM THE KLEINSCHMIDT FRACTIONATION OF EACH ASPHALT STUDIED WAS FOUND TO BE PROPORTIONAL TO THE GLC RETENTION BEHAVIOR OF THE TEST COMPOUND FORMAMIDE DETERMINED ON THE WHOLE ASPHALT. A COMMON COMPOSITIONAL FACTOR BETWEEN THE ASPHALTENES AND ASPHALTIC RESINS WAS INDICATED. AFTER OXIDATION OF THE ASPHALTS WITHIN THE GLC COLUMN, CORRELATIVE TRENDS WERE FOUND BETWEEN THE INVERSE GLC RETENTION BEHAVIOR OF THE TEST COMPOUNDS PHENOL AND PROPIONIC ACID, AND MEASURES OF ASPHALT DURABILITY PROPOSED BY ROSTLER AND WHITE. /AUTHOR/
