The properties and uses
of m-methyl anisole
1. Introduction

m-methyl anisole (m-Methylanisole) is a common raw material for the production of chemical products, with unique chemical properties and a wide range of industrial uses. In this paper, the properties and uses of m-methyl anisole are discussed in detail, in order to provide reference for the production practice in related fields.

2. the properties of methyl anisole

1. physical properties: methyl anisole is a colorless and transparent liquid with aromatic odor. Its boiling point is 154 ℃, melting point is -36.5 ℃, relative density is 0.994, insoluble in water, but miscible with most organic solvents.
2. Chemical properties: The chemical properties of m-methyl anisole are relatively stable, but under certain conditions, reactions such as substitution, oxidation and reduction can occur. For example, under acidic conditions, the methyl group of m-methyl anisole can be replaced by halogen; under basic conditions, the hydrogen atom on the benzene ring can be replaced. In addition, m-methyl anisole can also be oxidized to give the corresponding carboxylic acids and aldehydes.

3. the use of m-methyl anisole

1. As a solvent: m-methyl anisole has good solubility and can be used as a solvent for coatings, inks, resins and other fields. At the same time, due to its moderate boiling point, it can also be used as a distillation solvent.
2. As a reaction raw material: m-methyl anisole can be used as a reaction raw material to participate in a variety of organic synthesis reactions, such as Friedel-Crafts reaction, Ullman reaction and so on. Through these reactions, a series of important organic compounds can be synthesized, such as phenol, benzoic acid and so on.
3. As a spice: m-methyl anisole has aromatic odor and can be used as a spice in food, cosmetics and other fields.
Precautions in the production practice of
4.

In the production practice, the use of m-methyl anisole needs to pay attention to the following matters:

1. Storage: m-methyl anisole should be stored in a cool and ventilated warehouse, away from fire and heat sources. It should be stored separately from oxidants, acids and alkalis, and mixed storage is not allowed.
2. Transportation: The transportation of m-methyl anisole shall be carried out in accordance with the regulations on the transportation of dangerous goods. During the transportation, the container shall be protected from exposure to the sun and rain, and the container shall be kept sealed. It is strictly prohibited to mix with oxidants, acids, alkalis, edible chemicals, etc.
3. operation: the operation of methyl anisole personnel should be specially trained, strictly abide by the operating procedures. Fireworks shall be strictly prohibited at the operation site, and corresponding fire-fighting equipment and leakage emergency treatment equipment shall be provided.

5. conclusion

m-methyl anisole as a common chemical raw material, has unique chemical properties and a wide range of industrial applications. In production practice, we should fully understand its nature and use, strictly abide by the operating procedures to ensure production safety. At the same time, in view of the risks that may occur during the storage, transportation and operation of m-methyl anisole, corresponding preventive measures should be taken to ensure the safety of personnel and the environment.
