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.
1. the nature of m-xylene
m-xylene is a colorless transparent liquid with a pungent smell. Its molecular formula is C8H10 and its relative molecular mass is 106.17. M-xylene is insoluble in water, but is miscible with organic solvents such as alcohols, ethers, and acetone. m-Xylene has a boiling point of 139°C, a melting point of -47.9°C and a flash point of 25°C.
m-xylene has strong toxicity, long-term exposure or inhalation of m-xylene vapor will cause harm to the human body, causing headache, dizziness, nausea and other symptoms. Therefore, strict attention should be paid to safety measures during production and use.
2. m-xylene use
1.
in the field of medicine m-xylene has a wide range of applications in the field of medicine, is an important synthetic raw material for many drugs. For example, m-xylene can be used to synthesize the anti-tuberculosis drugs isoniazid and p-aminosalicylic acid.
2. Pesticide field
m-xylene is also an important raw material in pesticide production, which can be used to synthesize a variety of pesticides, fungicides and herbicides. For example, meta-xylene can synthesize the broad-spectrum insecticide trichlorfon.
3. Dye field
m-xylene in the field of dyes also has a wide range of applications, can be used to synthesize a variety of dyes, such as acid dyes, direct dyes, disperse dyes and so on.
4. perfume field
m-xylene can also be used as a raw material for the synthesis of spices, for the preparation of a variety of flavors and fragrances.
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. Because of its strong toxicity, it is necessary to pay strict attention to safety measures in the process of production and use. In the future, with the continuous development of science and technology, the application field of m-xylene will continue to expand.
