Preparation and Application of Paraffin Wax

Paraffin wax is the common name of solid higher alkane mixture. The molecular formula is CnH2n +2, where n =20~40. The excess residual oil in wax is removed by petroleum refining process. The oil is then separated by vacuum distillation. The main component of refined paraffin wax is saturated n-alkanes with carbon number of about 20-40, containing a small amount of isomers and alkanes.            

Preparation of paraffin wax          

Paraffin wax can be prepared from the waxy distillate fraction of natural or man-made petroleum by cold pressing, solvent dewaxing, sweating, etc.            

Paraffin wax is usually a white waxy solid with slight odor, with a melting point of 47 °C-64 ° C and a density of about 0.8g/cm3. It is insoluble in water, but soluble in ether, benzene and some esters. Paraffin wax does not react with common chemical reagents, but can burn.

Use of paraffin wax          

Pure paraffin wax is a good insulator with a resistivity of 1013-1017 ohm·m, which is higher than most materials except some plastics (especially Teflon).            

Paraffin wax is also a good heat storage material, with a specific heat capacity of 2.14 – 2.9 J·g – 1·K–1 and a melting heat of 200–220 J·g–1.            

Paraffin wax is the main component of candles.            

Paraffin wax can also be used to prepare detergent, emulsifier, dispersant, plasticizer, grease and so on. Are you looking for a professional paraffin supplier? Welcome to contact us. King Honor is your most reliable paraffin waxes partner.
