The first major type of crude oil, paraffin, which Elkins (alkanes) also called. Paraffin general formula is CnH2n + 2. The simplest and lightest series paraffin molecule, methane has the formula CH4. Paraffin with fewer than five carbon atoms are gaseous at normal temperature and pressures. In addition to methane, other gaseous paraffin include ethane, propane and butane. For simplicity, these are sometimes also called C1 to C4. C5 to C15 normal paraffin in the temperature and pressure of the liquid. Hydrocarbons with more than 15 carbon atoms (C15), highly viscous or viscous and solid waxes to their own state. Paraffin of the C40 and above all are.Paraffin wax against many acids and alkali resistant and suitable as corrosion protection coatings for industrial barrels and tanks. In addition, due to their remarkable properties as electrical insulation and has many applications in various industries including textile is used.
