Abstract

In this paper different properties of two paraffin waxes and two microcrystalline waxes have been studied using GC, DSC, FT-IR and conventional method of testing .Petroleum waxes are mixtures of hundreds and thousands of different hydrocarbons. Paraffin wax contains C18 to C40 straight chain saturated normal hydrocarbons whereas microcrystalline waxes are predominantly highly branched C27 to C68 hydrocarbons. Petroleum waxes were characterized by gas chromatography, Differential Scanning Calorimetry and FT-IR. The resulting GC, DSC and FT-IR data were correlated with various physical properties of the waxes, such as kinematic viscosity, needle penetration, melting point, refractive index, and flash point.
