Read： 1123 Time：20months ago Source：Transform the World with Simplicity

Cracked carbon five for industrial use is an important raw material for the production of chemical products, which is widely used in rubber, plastics, paints, coatings, pharmaceuticals, spices and other fields. This article will detail the nature and use of industrial pyrolysis carbon five.

1. properties

industrial cracking carbon five is a mixture, mainly composed of isoprene, cyclopentene, piperylene and so on. Its properties are as follows:

1. Colorless transparent liquid with pungent smell.
2. The density is about 0.65-0.75g/cm3, lighter than water.
3. The boiling point range is 60-100 ℃, flammable, steam and air can form an explosive mixture.
4. Insoluble in water, miscible with alcohol, ether, acetone and other organic solvents.
5 has a high degree of chemical activity, prone to addition, polymerization and other reactions.

2. uses

industry cracked carbon five in the chemical industry has a wide range of uses, mainly used in the following aspects:

1. synthetic rubber

industry cracked carbon five is an important raw material for synthetic rubber, can be used for the production of isoprene rubber, butadiene rubber and so on. Isoprene rubber has excellent wear resistance, tear resistance, flex resistance and other properties, widely used in the production of tires, rubber hose, tape and other products. Cis-polybutadiene rubber has the advantages of high elasticity, good wear resistance, low temperature resistance, etc., and can be used in the production of tires, conveyor belts, rubber shoes, etc.

2. synthetic resin

industrial cracking carbon five can be used for the production of phenolic resin, urea-formaldehyde resin and other synthetic resin. Phenolic resin has the advantages of heat resistance, acid resistance, water resistance, etc., and can be used to produce electrical insulation materials, wear-resistant materials, etc. Urea-formaldehyde resin has the advantages of water resistance, heat resistance and abrasion resistance, and can be used in the production of plywood and particleboard.

3. coatings and paint

industrial cracking carbon five can be used as raw materials for coatings and paints, which can improve the drying and hardness of coatings and improve the leveling and weather resistance of paints.

4. pharmaceutical and perfume

industry with cracking carbon five can be used to produce some pharmaceutical intermediates and spices, such as vitamin E, citral and so on.

In short, as an important chemical raw material, industrial pyrolysis carbon five has been widely used in rubber, plastics, paints, coatings, medicine, spices and other fields.
