O-xylene is an important organic chemical raw material, which is widely used in plastics, rubber, fibers, solvents and pesticides. It has special chemical and physical properties, so it is used to manufacture many important chemicals. This article will detail the nature and use of o-xylene.
1. the nature of ortho-xylene
1. physical properties
ortho-xylene is a colorless and transparent, aromatic smell of liquid, insoluble in water, but can be miscible with many organic solvents. It has a boiling point of 137°C, a density of 0.88 g/cm and a flash point of 25°C. Ortho-xylene has high volatility and is easy to volatilize and burn.
2. chemical properties
o-xylene chemical properties are relatively stable, not easy to be oxidized and reduced, but can occur substitution reaction and addition reaction. There are two adjacent methyl groups on the benzene ring of o-xylene, which makes its chemical properties different from benzene. It can be substituted with halogen, acid, base, etc. to generate a variety of derivatives. In addition, o-xylene can also undergo addition reactions, such as the addition of hydrogen to generate methylcyclohexane.
2. of ortho-xylene use
1.
of the plastic and rubber industry ortho-xylene is an important raw material for the plastic and rubber industry, which can be used in the production of polystyrene, ABS resin, SAN resin and other plastic products. These plastic products have excellent impact resistance, heat resistance, chemical resistance and other properties, widely used in home appliances, automobiles, construction and other fields.
2.
in the fiber industry Ortho-xylene can be used to produce polyester fiber. Polyester fiber is a synthetic fiber with excellent elasticity, abrasion resistance, wrinkle resistance and other properties. It is widely used in clothing, home textiles and other fields.
3. solvent industry
o-xylene is an excellent organic solvent, can be used to dissolve many organic matter, such as resin, paint, ink, etc. It also has low toxicity and good volatility, so it is widely used in printing, coatings, adhesives and other fields.
4. Pesticide industry
o-xylene can be used to produce some pesticides, such as insecticides, fungicides, etc. These pesticides have a good control effect on crop diseases and insect pests, and play an important role in ensuring agricultural production and food security.
In short, o-xylene, as an important organic chemical raw material, has a wide range of applications in the fields of plastics, rubber, fibers, solvents and pesticides. With the continuous development of science and technology, the use of o-xylene will continue to expand, bringing more contributions to human production and life.
