What is paraffin? Paraffin wax is a general term for a mixture of solid higher alkanes. Let’s see together below how to write the chemical formula of paraffin, what paraffin is used for and what paraffin is used for.
Chemical formula of paraffin wax: CnH2n + 2, where n=20~40.
Paraffin wax is a white waxy solid with a slight odor. It can be produced from natural or artificial oil-wax fractions by cold pressing or solvent dewaxing, penetration and other processes.
Fully refined paraffin wax 58-60 is a solid crystalline product derived from petroleum. It is a variety of hydrocarbons, i.e. a mixture of hydrocarbons with different molecular weights. It consists mainly of normal paraffins with small amounts of solid isoparaffins, cycloalkanes and a small amount of aromatic hydrocarbons. Commercial paraffin wax typically has a carbon number between 22 and 36, a molecular weight between 360 and 540, and a boiling point between 300 and 550 degrees Fahrenheit. As the molecular weight, boiling point and melting point of the paraffin wax increase, the normal paraffin in the composition decreases while the solid isoparaffin and naphthenes increase. The chemical composition of paraffin from different crudes is also different.
