　　Do you know the difference between paraffin wax and liquid paraffin wax?

　　paraffin:

　　Paraffin wax, also known as crystalline wax, a mixture of hydrocarbons with a carbon atom number of 18 to 30, the main components are straight-chain alkanes (about 80% to 95%), as well as a small number of alkanes with individual branched chains and monocyclonic alkanes with long side chains (the combined content of the two is less than 20%). Paraffin wax is a wax paste made from crude oil distillation and lubricating oil distillation by solvent refining, solvent dewaxing or wax freezing crystallization, pressing dewaxing, and then degreasing, and supplemented with refined flake or needle crystals. According to the degree of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and coarse paraffin. Each type of wax is divided into different varieties according to the melting point, generally every 2 ° C, such as 52, 54, 56, 58 and other grades.

　　Coarse paraffin has a high oil content and is mainly used to make matches, fiberboard, tarpaulin, etc. Fully refined paraffin wax and semi-refined paraffin wax are widely used, mainly used as components and packaging materials for food, oral medicines and certain commodities (such as wax paper, crayons, candles, copy paper), baking container coating materials, for fruit preservation, electrical component insulation, improve rubber aging resistance and increase toughness, etc., can also be used for oxidation to generate synthetic fatty acids.

　　Liquid paraffin wax:

　　Mixtures of various n-alkanes with melting points below 40 °C than from C10 to C18. Sometimes white oil is also called liquid wax, but there are obvious differences in structure. It is made of light distillate oil such as kerosene and diesel oil through molecular sieve and cold press dewaxing, concentrated sulfuric acid refining, alkali washing, and water washing. According to the fraction can be divided into (light) liquid paraffin and heavy liquid paraffin, as well as various n-alkane monomers from C11 to C18 or mixtures of several n-alkanes. The volatile properties and kinematic viscosity of each n-alkane are different, resulting in various applications.

　　Light wax generally contains C9-C13, heavy wax generally contains C13-C16, the main uses include detergent raw materials, cosmetics, daily necessities thinners, solvents and so on.
