Review of kunlun paraffin wax market in 2022
2023-03-31 No Comments
In 2022, the overall price change of domestic kunlun paraffin wax market showed a trend of “rising first and then fluctuating downward”.
Normal paraffin (from Latin parum “little” + affinis “related”) is a wax-like mixture of saturated hydrocarbons (alkanes) with a predominantly normal structure of composition from C18H38 (octadecane) to C35H72 (pentatriocontane).
Melting point – from 45°С to 65°С;
Density – 0.880-0.915 g / cm³ (15 ° C);
When heated above 90 ° C, normal paraffin in air begins to intensely soar without boiling. Dense vapors of normal paraffin heated to 120-150°C self-ignite upon contact with air.
Depending on the ratio of concentrations of heavy and light hydrocarbons, paraffin can be liquid, solid and finely crystalline (ceresin).
The effect that occurs when water is mixed with boiling paraffin. Normal paraffin is a white substance with a molecular weight of 300-450, in the molten state it has a low viscosity.
Paraffin is inert to most chemicals. They are oxidized by nitric acid, atmospheric oxygen (at 140 °C and above) and some other oxidizing agents to form various fatty acids similar to those found in vegetable and animal fats. Synthetic fatty acids obtained by paraffin oxidation are used instead of vegetable and animal fats in the perfume industry, in the production of lubricants, detergents, and food products.

Normal paraffin can also be isolated from other products, for example, from ozokerite. Depending on the fractional composition, melting temperature and structure, normal paraffins are divided into liquid (tmelt ≤ 27 °C), solid (tmelt = 28-70 °C) and microcrystalline (tmelt > 60-80 °C) – ceresins. At the same melting point, ceresins differ from normal paraffins in their greater molecular weight, density, and viscosity.
Ceresins react vigorously with fuming sulfuric acid, while normal paraffins react weakly with it. During the distillation of oil, ceresins are concentrated in the sediment, and normal paraffin is distilled with distillate. Ceresins, which are concentrated in the residue after the distillation of fuel oil, are a mixture of cycloalkanes and, in a smaller amount, solid arenes and alkanes. There are relatively few isoalkanes in ceresin.
According to the degree of purification, normal paraffins are divided into the following types:
slack and petrolatum, which contain up to 30% (wt.) oils;
crude normal paraffins (ceresins) with oil content up to 6% (wt.);
purified and highly purified normal paraffin (ceresins).

The candle machine is a machine that makes a candle. By making the mold that needs to be required, the candle raw material is infused into the candle machine, and the candle can be formed after cooling.
About the waxing process of candle machine
1. Follow wax: Add some water to the pot, put the solid paraffin into the pot (can melt the paraffin into wax water), melt it into liquid wax water until the pot is added to the configuration pigment color.
Soy Wax is a vegan wax made from the complete oiling of soybeans. Like honey, it is considered a natural wax, and 100% pure soy wax is often used in containers of soy wax.
Paraffin wax is a hydrocarbon mixture extracted from some distillates of petroleum, shale oil or other bituminous mineral oils. The main component is solid alkanes, odorless and tasteless, and it is a white or light yellow translucent solid.
Paraffin is a purified mixture of solid saturated hydrocarbons. Paraffin wax is a flaky or needle-like crystal obtained from lubricating oil fractions obtained by distillation of crude oil through solvent refining, wax freezing crystallization, and press dewaxing to obtain wax paste, and then solvent deoiling and hydrofining.
