Methyl salicylate is an organic compound, which is widely used in the field of chemical production raw materials. It has a special fragrance and irritation, and can be used to make spices, medicines and plastics. This article will detail the properties and uses of methyl salicylate.

1. the nature of methyl salicylate

methyl salicylate molecular formula C8H8O3, molecular weight of 152.15. It is a colorless to yellowish transparent liquid with a strong smell of wintergreen oil. Methyl salicylate is insoluble in water, but soluble in ethanol, ether, acetone and other organic solvents. It has a melting point of -8.6°C, a boiling point of 218-224°C and a flash point of 100°C.

methyl salicylate has strong irritation and corrosiveness, and has irritating effect on eyes, skin and respiratory tract. Therefore, it is necessary to wear protective equipment when handling methyl salicylate to avoid contact with eyes and skin.

2. The use of methyl salicylate

1. Fragrance manufacturing

methyl salicylate has a special fragrance and can be used to manufacture spices and flavors. It is often used as an important ingredient in the deployment of floral, fruity and other fragrances, and is widely used in the fields of food, daily necessities and cosmetics.

2. drug production

methyl salicylate has anti-inflammatory, analgesic, antipruritic and other effects, commonly used in the treatment of muscle pain, arthritis, skin itching and other diseases. Therefore, methyl salicylate is an important raw material in pharmaceutical production.

3. Plastic Additive

Methyl salicylate can be used as a plastic additive to improve the processing and mechanical properties of plastics. It can improve the toughness, hardness and heat resistance of the plastic, and extend the service life of the plastic.

4. organic synthesis intermediate

methyl salicylate can also be used as an organic synthesis intermediate for the synthesis of other organic compounds. For example, it can be used to synthesize salicylic acid, benzoic acid and other compounds, and further prepare a series of important chemical products and drugs.

In short, methyl salicylate has a wide range of uses in the field of chemical production raw materials, can be used as spices, drugs, plastic additives and organic synthesis intermediates. However, it is necessary to pay attention to the irritation and corrosion of methyl salicylate when operating, and take necessary protective measures to ensure production safety.
