CHARACTERIZATION OF PETROLEKUM WAXES BY HIGH TEMPERATURE GAS CHROMATOGRAPHY - CORRELATION WITH PHYSICAL PROPERTIES

摘要

Hydrocarbon waxes of different composition were characterized by high temperature gas chromatography. The resulting GC data were correlated with various physical properties of the waxes, such as needle- penetration, refractive index, melting point, and kine- matic viscosity. In addition to HTGC, SFC was also per- formed. Comparison of chromatographic techniques for the separation of n-alkanes from waxes by HTGC and SFC were also done. Key Words: HTGC (high temperature gas chromatography), SFC (super critical fluid chromato- graphy) and Petroleum waxes.
