Candle is a daily lighting tool, mainly made of paraffin. In ancient times, it was usually made of animal fat. It can burn and emit light. In addition, candles have a wide range of uses: they are also used in activities such as birthday parties, religious festivals, collective mourning, and weddings and funerals.

The main raw material of candles is paraffin (C₂₅H₅₂), which is obtained from the waxy fraction of petroleum by cold pressing or solvent dewaxing. It is a mixture of several higher alkanes, mainly n-docosane (C22H46) and n-two Octadecane (C28H58) contains about 85% carbon elements and about 14% hydrogen elements. Added auxiliary materials include white oil, stearic acid, polyethylene, essence, etc. Among them, stearic acid (C17H35COOH) is mainly used to improve softness, and the specific addition depends on what kind of candles are produced.

Paraffin wax chemical formula: CnH2n + 2, where n = 20-40.

What is paraffin wax? Kunlu Paraffin Wax is a waxy white solid with a mild odor. It can be made from the waxy fraction of natural or synthetic oil by cold pressing or dewaxing with a solvent, penetrant and other methods.

Paraffin wax is a solid crystalline product that is extracted from petroleum. It is a mixture of several hydrocarbons, i.e. hydrocarbons of different molecular masses. It consists mainly of normal paraffin and some solid isoparaffins, cycloalkanes and small amounts of aromatic hydrocarbons. Commercially available paraffin waxes typically have a carbon number of 22 to 36, a molecular weight of 360 to 540, and a boiling point of 300 to 550 °C. As the paraffin wax melts, the normal paraffin in the composition decreases and the isoparaffin and solid naphthene increase. The chemical composition of the paraffins of different crude oils is also different.

Yellow paraffin wax or unrefined wax contains traces 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. Because some condensed ring aromatic hydrocarbons contained in a small amount of paraffin aromatic compounds are harmful to the human body, they are paraffins used in the food and pharmaceutical industries, so condensed ring aromatic hydrocarbons are used. It must be less than the index defined above.

In some laboratory analyzes of paraffin with mass spectrometers, when the chemical composition information for each fraction is divided by the number of carbon atoms in the molecule, all fractions with the fewest carbon atoms in the molecule are normal alkanes. The proportion of carbon atoms increases, the concentration of isoparaffins and cycloalkanes increases, and the aromatic compounds of the wax are only present in the carbonaceous fraction. Therefore, under the same cleaning conditions, in a typical commercial paraffin wax, the concentration of aromatic hydrocarbons in the melting cycle of the low-quality wax is lower than that of the high-quality wax.

Kunlun paraffin wax is a mixture of hydrocarbons, so it does not have a precise melting point for pure compounds. The so-called melting point of paraffin wax is the temperature at which a stagnation period appears for the first time in the cooling curve when a molten paraffin sample is cooled under certain conditions. All wax products require paraffin wax with excellent heat resistance. That is, it does not melt, soften or mold at any particular temperature. Depending on the conditions of use, the region and season, and the environment of use, commercially available paraffin waxes must have several different melting points.

The biggest factor influencing the melting point of paraffin wax is the weight of the selected raw material fraction. The melting point of paraffin wax in heavy fractions is high. In addition, oil has a large effect on the melting point of paraffin wax. The more oil in paraffin wax, the lower its melting point.
