M-xylene is an important raw material for chemical production, which is widely used in medicine, pesticide, dye, spice and other fields. This article will detail the properties and uses of m-xylene.

one, the nature of m-xylene

m-xylene is a colorless transparent liquid, with a special smell. Its molecular formula is C8H10, structural formula is CH3-C6H4-CH3, belonging to aromatic hydrocarbon compounds. M-xylene has a boiling point of 139°C, a melting point of -47.9°C, a relative density of 0.86°C, and is insoluble in water, but miscible with organic solvents such as alcohols, ethers, and acetone.

m-xylene has strong chemical stability, is not easy to be oxidized and reduced, but can occur substitution reaction, addition reaction and so on. In addition, m-xylene is also toxic and flammable, requiring safety during storage and use.

2. the use of m-xylene

1.

in the field of medicine m-xylene in the field of medicine has a wide range of applications, mainly for the production of drugs and medical supplies. For example, m-xylene can be used as a raw material to produce anti-inflammatory drugs, antibacterial drugs, anti-tumor drugs, etc. In addition, m-xylene can also be used to produce vitamin B1, vitamin K1 and other drugs.

2. Pesticide field

m-xylene also has important applications in the field of pesticides, mainly for the production of pesticides, fungicides, herbicides and other pesticides. For example, m-xylene can be used as a raw material to produce pyrethroid insecticides, which has the advantages of high efficiency, low toxicity and low residue, and is widely used in agricultural production and household health pest control.

3. Dye field

m-xylene in the dye field also has a wide range of applications, mainly for the production of various pigments and dyes. For example, m-xylene can be used as raw materials to produce dyes such as Yonggu purple RL, Yonggu purple RR, Yonggu pink F3R, etc., which are widely used in textile, printing and dyeing, plastics and other industries.

4. spice field

m-xylene in the spice field also has a certain application, mainly for the production of artificial musk and other spices. For example, m-xylene can be used as a raw material to produce methylcyclopentenolone, which is an important artificial musk fragrance and is widely used in perfumes, cosmetics and other fields.

In short, m-xylene, as an important raw material for the production of chemicals, has been widely used in the fields of medicine, pesticides, dyes, spices and so on. With the continuous development of science and technology, the application field of m-xylene will continue to expand.
