Paraffin wax |
1. Paraffin wax, also known as crystalline wax, is a kind of non-polar solvent soluble in gasoline, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha and other non-polar solvents, and insoluble in polar solvents such as water and methanol. Sexual solvent.
2. A mixture of hydrocarbons with approximately 18 to 30 carbon atoms. The main components are linear alkanes (approximately 80% to 95%), as well as a small amount of alkanes with individual branch chains and monocyclic rings with long side chains. Alkanes (the total content of both is less than 20%). Paraffin wax is a flaky or needle-shaped crystal obtained from the lubricating oil fraction obtained by distillation of crude oil through solvent refining, solvent dewaxing or wax freeze crystallization, press dewaxing to obtain wax paste, and then deoiling and refining. According to the different degrees of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.
3. Each type of wax is divided into different varieties according to its melting point, usually every 2ºC, such as 52, 54, 56, 58 and other brands. Crude paraffin has a high oil content and is mainly used to make matches, fiberboards, canvas, etc. Fully refined paraffin wax and semi-refined paraffin wax are widely used. They are mainly used as components and packaging materials for food, oral drugs and certain commodities (such as wax paper, crayons, candles, copy paper), as coating materials for baking containers, and for fruit preservation. , Insulate electrical components, improve rubber aging resistance and increase flexibility, etc. It can also be used for oxidation to produce synthetic fatty acids.
