Solubility measurement of oil in hexane was conducted in a
closed jacketed reactor and the mixture was mixed continuously.
The reactor was maintained at different temperature, controlled
by a RC (LAUDA) water bath. After 30 min, an aliquot of supernatant
solution was extracted into a sample bottle, weighed to obtain
the solution withdrawn. After distillation and evaporation of solvent,
the weight of oil was determined. Oil solubility in petroleum
ether and hexane was measured
