Introduction of paraffin wax

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.

What paraffin wax consists of

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.

Yellow paraffin 58-60 Fully refined or lightly refined wax still contains small amounts of non-hydrocarbon components. Although these complex organic compounds of sulfur, nitrogen and oxygen contain only small amounts, the stability of paraffin wax is greatly reduced. Some cyclic aromatic hydrocarbons in a small amount of aromatic compounds in paraffin are harmful to the human body, therefore, in paraffin used in the food industry and medicine, condensed cyclic aromatic hydrocarbons should be reduced below the above-mentioned ratio. It can be used.
In laboratory analysis of certain paraffins using a mass spectrometer, the chemical composition data of each fraction divided by the number of carbon atoms in the molecule shows that the fraction with the fewest number of carbon atoms in the molecule are all normal and numbered alkanes. the number of carbon atoms increases, the concentration of isoparaffins and cycloalkanes increases, and the aromatic compounds contained in waxes occur only in the carbon parts. Therefore, when the refining conditions are the same, the content of molten cyclic aromatic hydrocarbons in the bottom wax is lower in commercial slack wax than in the top wax.

Fully refined paraffin 58-60 is a mixture of hydrocarbons, so it does not have such a high melting point as pure compounds. The so-called paraffin wax melting point describes the temperature at which the stagnation phase in the cooling curve first appears when the molten paraffin sample is cooled under certain conditions. All wax products require the paraffin wax to have good temperature stability, i.e. it will not melt, soften or form at a certain temperature. Commercially available paraffin waxes must have several different melting points depending on the conditions of use, areas of use and seasons, as well as variations in the environment of use.
The factor that has the greatest impact on the melting point of paraffin is the weight of the selected fraction of the raw material. The heavier fraction of paraffin wax has a higher melting point. In addition, the oil content has a strong influence on the melting point of the paraffin: the higher the oil content of the paraffin, the lower its melting point.
