of the properties and uses
of methyl cyclohexanone Methyl cyclohexanone is an important organic chemical raw material, widely used in the production of pharmaceuticals, pesticides, spices, dyes and various fine chemicals. In this paper, the properties and uses of methylcyclohexanone will be described in detail.
1. the properties of methylcyclohexanone
methylcyclohexanone is a colorless transparent liquid with a pleasant smell. Its molecular formula is C7H12O, and its structure contains carbonyl group and cyclohexyl group, which makes methyl cyclohexanone have many unique chemical properties.
1. Physical properties
The boiling point of methylcyclohexanone is 194~195 ℃, the density is 0.947g/cm3, the refractive index is 1.4505, and the flash point is 74 ℃. It is poorly soluble in water, but is miscible with organic solvents such as alcohols, ethers, and benzene.
2. chemical properties of
methyl cyclohexanone carbonyl with typical chemical properties of ketone compounds, such as with Grignard reagent, hydrocyanic acid and other addition reaction, alcohol reduction to alcohol. In addition, methylcyclohexanone may be subjected to substitution reactions such as halogenation, nitration, and sulfonation.
2. the use of methyl cyclohexanone
As an important chemical raw material, methyl cyclohexanone is widely used in the following fields:
1. Pharmaceutical intermediate
methyl cyclohexanone can be used as a pharmaceutical intermediate for the production of anti-inflammatory, anti-cancer, anti-fungal and other drugs. For example, methylcyclohexanone is condensed with acetophenone to give acetophenone ketal, an important anti-inflammatory drug.
2. pesticide production
methyl cyclohexanone can be used for the production of pesticides, such as insecticides, fungicides. For example, the reaction of methylcyclohexanone with chloroformates gives highly effective insecticides.
3. Perfume Making
Methylcyclohexanone has a pleasant odor and can be used in perfume making. It can be used as an ingredient of essence and is widely used in food, cosmetics and other fields.
4. Dye production
Methylcyclohexanone can be used as an intermediate in dye production for the synthesis of dyes of various colors. For example, the reaction of methylcyclohexanone with aniline gives a red aniline dye.
In conclusion, as an important organic chemical raw material, methylcyclohexanone has a wide range of applications in the fields of medicine, pesticides, spices, dyes and so on.
