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,paraffin in air begins to intensely soar without boiling. Dense vapors of paraffin heated to 120-150°C self-ignite upon contact with air.
Obtained mainly from oil.
Depending on the ratio of concentrations of heavy and light hydrocarbons,paraffin can be liquid, solid and finely crystalline (ceresin).
normal paraffin is a white substance with a molecular weight of 300-450, in the molten state it has a low viscosity.
normal paraffins are 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 normal paraffin oxidation are used instead of vegetable and animal fats in the perfume industry, in the production of lubricants, detergents, and food products.
Receipt
normal paraffins 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 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.
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.
With the increasing popularity of scented candles, and the diversification of various candles, events need to be held, the atmosphere needs and incense. The demand for raw materials to make candles is also increasing.
