Butenol is an important organic chemical raw material, widely used in medicine, pesticides, spices, plastics and synthetic rubber and other fields. This article will detail the properties and uses of butenol.

1. the nature of butenol

butenol is a colorless transparent, pungent odor of liquid, molecular formula C4H8O, structural formula CH3CH = CHCH2OH. It has the following properties:

1 volatile: Butenol has a strong volatility, volatile into a gas.

2. Solubility: Butenol can be dissolved in water, ethanol, ether and other organic solvents.

3. Acidity: Butenol has a certain acidity, can react with alkali to generate salt.

4. reducibility: butenol has strong reducibility and can be oxidized to butyraldehyde or butyric acid.

5. instability: butenol easy to occur from the polymerization reaction, the formation of polymer.

2. butenol use

1.

in the field of medicine butenol can be used in the production of a variety of pharmaceutical intermediates, such as for the production of anti-tuberculosis drugs isoniazid, anti-tumor drugs such as cyclophosphamide. In addition, butenol can also be used to produce vitamin B1, vitamin B6 and other nutritional drugs.

2.

in the field of pesticides Butenol can be used as pesticide intermediates for the production of fungicides, insecticides and other pesticides. For example, butenol can react with chlorine to produce 2-chlorobutene, and then react with phosgene to produce 2,3-dichloroacrylate methyl ester, and finally make the fungicide rice blast net.

3. fragrance field

butenol has a strong fragrance and can be used to produce a variety of fragrances, such as clove oil, eugenol, etc. These spices are widely used in food, cosmetics and other industries.

4.

in the field of plastics and synthetic rubber Butenol can be used as a monomer to generate polymers through polymerization for the production of plastics and synthetic rubber. For example, butenol can be copolymerized with styrene to form styrene-butadiene rubber, which is widely used in the production of rubber products such as tires and rubber hoses.

In short, as an important organic chemical raw material, butenol has a wide range of applications in the fields of medicine, pesticides, spices, plastics and synthetic rubber.
