Abstract

As for a study on the treatment of asphalt with metal chloride, the influence of paraffinic compounds on the increase of asphaltene content was pursued.<BR>n-Dodecane was made a selection as paraffinic compounds and reacted at temperature 180-200C 200C using aluminum chloride as catalyst. Heavy oils procuced were isolated to n-pentane solubles (A) and insolubles (B). Comparison of NMR spectra of B and asphaltene of straight asphalt showed that B was asphaltene-like matter.<BR>A was fractionated to three eluates (n-pentane eluate, benzene eluate and chloroform-methanol eluate) by alumina column chromatography and investigated by means of NMR, GC-Mass spectrometry, elementary analysis, molecular weight and structural parameters. Being based on these fractions, the process of production of heavy oils from n-dodecane was surmissed as Fig.7.<BR>From these results, it was suggested-that paraffinic compounds of asphalt were possible to contribute to the increase of asphaltene content.
