摘要：An alternative method to obtain petroleum ether equivalent is described in this study. Two fractions of benzin were obtained, by fractional distillation of available and less expensive benzin, with yield of 13.78 and 18.44% or 32.22% the both. The aptitude of the first fraction was investigated to extract fat. Comparative extractions were done against hexan, heptan and petroleum ether 40-60°C. It was demonstrated that the extracting power of these solvents is comparable. This result may be a very good alternative for researcher from African countries to prepare some liters of solvent for laboratories usage.
