Abstract
In order to study the dependence of penetration on the physical and molecular characteristics of paraffin waxes, one stage fractional crystallization has been done to separate the paraffin waxes with different characteristics by using different solvents and solvent mixtures at various fractioning temperatures. The solvents used are methyl acetate (MA) and methyl tertiary butyl ether (MTBE) and the solvent mixtures are methyl ethyl ketone (MEK) containing toluene (T) and MEK containing toluene (T) and benzene (B). The effect of needle penetration on the physical and molecular characteristics of isolated paraffin waxes was also studied at different fractionating temperatures ranging from 20–0°C.
