Isopropenyl acetate is an important organic chemical raw material, widely used in medicine, pesticides, spices, coatings and other fields. This article will detail the properties and uses of isopropenyl acetate.

1. the properties of isopropenyl acetate

Isopropenyl acetate is a colorless transparent liquid with a pleasant fruity aroma. Its molecular formula is C5H8O2, structural formula is CH3COOCH = CH2. Isopropenyl acetate has high volatility and flammability. When exposed to open flame, high heat or oxidant, it is dangerous to cause combustion and explosion.

isopropenyl acetate has good solubility and can be miscible with a variety of organic solvents, such as ethanol, ether, acetone and so on. In addition, isopropenyl acetate also has good chemical stability, but is prone to hydrolysis under acidic and alkaline conditions.

2. The use of isopropenyl acetate

1.

in the field of medicine In the field of medicine, isopropenyl acetate is commonly used as an intermediate in the synthesis of drugs, which can be used to synthesize antibacterial drugs, anti-inflammatory drugs, anticancer drugs and other drugs. For example, isopropenyl acetate can be reacted with phenol to produce isopropenyl benzoate, which is further reacted to produce the anti-tuberculosis drug isoniazid.

2. Pesticide Field

In the field of pesticides, isopropenyl acetate can be used to synthesize a variety of pesticides, such as insecticides, fungicides, herbicides, etc. For example, isopropenyl acetate can be reacted with a chlorinated hydrocarbon to form isopropenyl chloroacetate, which is further reacted to form the broad spectrum fungicide triadimefon.

3. Fragrance Field

In the field of fragrances, isopropenyl acetate has a pleasant fruit aroma and can be used to formulate a variety of edible and daily fragrances. For example, isopropenyl acetate can be reacted with ethanol to produce isopropenyl acetate ethyl ester, which is further reacted to produce flavoring ethyl vanillin.

4.

in the field of coatings, isopropenyl acetate can be used as a solvent and diluent to improve the fluidity and construction performance of coatings. In addition, isopropenyl acetate can also be copolymerized with other monomers to produce polymer emulsions for the preparation of waterborne coatings.

In conclusion, isopropenyl acetate, as an important organic chemical raw material, has a wide range of applications in the fields of medicine, pesticides, spices, coatings and so on.
