Petroleum liquid paraffin, fraction C14–C17

Petroleum paraffin liquid fractions C14–C17 are obtained as a result of fractional distillation of oil. This fraction includes alkanes with 14-17 carbon atoms and has stable physical properties, which makes it in demand in the production of cosmetics, lubricants and various chemical mixtures.

Chemical structure and synthesis

The composition of this fraction is a mixture of linear and branched alkanes, the formula of which can be conditionally written as:

CnH2n+2 where n=14-17.

Synthesis takes place by the industrial method of fractional distillation of oil, followed by refining to remove impurities and obtain pure saturated hydrocarbons.

Physico-chemical properties

• Low viscosity: Provides easy distribution and mixing with other components.

• Hydrophobicity: It is practically insoluble in water, which is typical for saturated hydrocarbons.

• Chemical stability: Low reactivity due to the absence of active functional groups.

• Melting and boiling: The fraction is characterized by a narrow range of melting and boiling temperatures, which is convenient for processing technologies.

Application

• Cosmetics: It is used in creams, lotions and other care products as an emollient and emulsifying component.

• Lubricants: It is used as a base for lubricants and protective coatings.

• Chemical industry: It is used as a solvent and a phase-forming component in various technological processes.

Conclusion

Liquid petroleum paraffin fraction C14–C17 is a versatile component characterized by stability, low viscosity and high purity, which allows it to be used in cosmetics, lubricants and a number of other industrial processes.
