Paraffin waxes have a distinctive crystalline structure, are pale yellow to white (or colorless) and have a melting point range between 122 and 140°F (50 and 60°C).

Paraffin wax was first produced commercially in 1867, less than 10 years after the first petroleum well was drilled. Paraffin wax precipitates readily from petroleum on chilling.  

Technical progress has served only to make the separations and filtration more efficient and economical.  

Purification methods consist of chemical treatment, decolorization by adsorbents, and fractionation of the separated waxes into grades by distillation, recrystallization, or both. Crude oils differ widely in wax content. sales3 at paraffinco dot com.
