3) Liquid paraffin wax is also used for disinfection and anti-embroidery of medical devices, and the specific effect is mixed.

Extended information: Chemical properties of paraffin.

Paraffin wax is a mixture of solid higher alkanes, and the molecular formula of the main component is CNH2N+2, where n=17 35. The main components are linear alkanes, as well as a small amount of alkanes with individual branched chains and monocyclic naphthenes with long side chains; The main types of linear alkanes are n-docadene (C22H46) and n-octadecane (C28H58).

Paraffin does not react with common chemical reagents, but it can be burned. Catalytic cracking reactions can occur industrially.

The paraffin wax has low chemical activity, is neutral, chemically stable, and does not interact with acids other than nitric acid and alkaline solutions under normal conditions.

Liquid paraffin wax is used in the manufacture of laundry detergents, synthetic detergents, synthetic petroleum proteins, pesticide emulsifiers, mechanical lubricants, etc.

Liquid paraffin is a mineral oil, but also a petrochemical product, liquid paraffin is a colorless translucent oil, so what are the uses of liquid paraffin? Let's find out.

or other bituminous mineral oils.

A mixture of hydrocarbons extracted from some of the distillates, the main component of which is solid alkanes.

It is odorless and tasteless, and is a white or light yellow translucent solid.

Paraffin, also known as crystalline wax, is a soluble in gasoline, carbon disulfide, and xylene.

Ether, benzene, chloroform.

A class of non-polar solvents such as tetrachloride Xiangjing carbon and naphtha are insoluble in water and methanol.

Isopolar solvents.

A mixture of hydrocarbons with a carbon atom number of about 18 30, the main components are linear alkanes (about 80% 95%), and a small amount of alkanes with individual branched chains and monocyclic naphthenes with long side chains (the total content of the two is less than 20%). Paraffin wax is a wax paste prepared by solvent refining, solvent dewaxing or wax freezing crystallization, pressing and dewaxing obtained from the lubricating oil fraction obtained by distillation, and then deoiled and supplemented with refined flake or needle crystals. According to the degree of processing and refinement, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.

Each type of wax is divided into different varieties according to the melting point, generally every 2 years, such as 52, 54, 56, 58 and other grades. Crude paraffin wax has a high oil content and is mainly used in the manufacture of 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 drugs and some commodities (such as wax paper, crayons, candles, carbon paper), coating of baking containers, fruit preservation, insulation of electrical components in withering, improving rubber aging resistance and increasing flexibility, etc.

It can also be used for oxidation to produce synthetic fatty acids.

Paraffin wax is a mixture of hydrocarbons extracted from certain distillates of petroleum, shale oil or other bituminous mineral oils, and is a type of mineral wax or petroleum wax. Paraffin, also known as microcrystalline paraffin, white paraffin, and crystalline wax, is a white, odorless waxy solid at room temperature.

Paraffin wax is soluble in non-polar solvents such as gasoline, ether, carbon disulfide, xylene, chloroform, carbon tetrachloride, etc., and insoluble in polar solvents such as water and methanol.

Paraffin wax is amorphous, but has an obvious crystal structure, and is often used in the preparation of high-grade fatty acids, high-grade alcohols, electrical insulating materials, matches, candles, ointments, etc.

According to the different degrees of processing and refining, paraffin wax can be divided into three types: fully refined paraffin, semi-refined paraffin wax and crude paraffin, and fully refined paraffin and semi-refined paraffin wax are widely used and are mainly used for food, medicine, commodity composition or packaging materials.
