The physical and chemical properties of paraffin wax are as follows:

I. Physical Properties

1, also known as crystalline wax, usually white, odorless waxy solid, melting at 47 ° C - 64 ° C, density of about 0.9g/cm?

2, paraffin wax is soluble in gasoline, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha and other non-polar solvents of a class, insoluble in water and methanol and other polar solvents. Pure paraffin is a good insulator, its resistivity is 1013-1017 ohm-meter.

Two, chemical properties

1, paraffin wax number of carbon atoms of about 18 ~ 30 hydrocarbon mixture, the main component for the straight-chain alkanes (about 80% ~ 95%), there are a small number of alkanes and alkanes with individual branched chains and with a long side-chain of the monocyclic cycloaliphatic hydrocarbons (the two combined content of less than 20%).

2, paraffin wax does not react with common chemical reagents, but can be burned. Catalytic cracking reaction can occur in industry.

3, paraffin wax chemical activity is low, neutral, chemically stable, in the usual conditions do not interact with the acid in addition to nitric acid and alkaline solutions.

Paraffin Wax Uses:

1. Crude paraffin wax, because of the oil content, is mainly used in the manufacture of matches, fiberboard, tarpaulin, and so on. Paraffin wax in the addition of polyolefin additives, its melting point increases, adhesion and flexibility increase , widely used in moisture-proof, waterproof wrapping paper, cardboard, some textiles surface coating and candle production.

2, the paper will be immersed in paraffin wax can be produced after a good waterproof performance of various waxed paper, can be used for food, pharmaceuticals and other packaging, metal rust and printing industry; paraffin wax to join the cotton yarn, can make the textiles soft, smooth and flexible; paraffin wax can also be made of detergents, emulsifiers, dispersants, plasticizers, grease and so on.

3, fully refined paraffin wax and semi-refined paraffin wax has a wide range of uses, mainly used as food, oral medicines and some components of goods and packaging materials. Baking container coating material for fruit preservation, insulation of electrical components, improve rubber aging resistance and increase flexibility. It can also be used to generate synthetic fatty acids by oxidation.
