[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods, isopropyl alcohol raw materials are what.

Isopropenyl alcohol properties

Isopropenyl alcohol (Isopropenyl Alcohol), molecular formula C3H6O, molecular weight of 58.08g/mol, is a colorless flammable liquid. Its chemical structure is CH2 = C(CH3)OH, with a double bond, showing olefin-like characteristics. Isoallyl alcohol has high reactivity, especially in acid-catalyzed conditions prone to polymerization. It has a boiling point of 92°C, a density of 0.79g/cm³, a refractive index of 1.377, a flash point of 11°C, and is soluble in water and many organic solvents. Due to the presence of its double bond and hydroxyl group, isoallyl alcohol exhibits diverse reactivities in chemical reactions.

Isopropenyl alcohol use

Isopropenyl alcohol is widely used in industry, mainly including the following aspects:

1. Polymer Synthesis Isopropenyl alcohol is often used as a monomer or comonomer for polymers. For example, it can be involved in the production of polymethacrylate materials for applications in coatings, adhesives and sealants.

2. Pharmaceutical and pesticide intermediates: In the pharmaceutical industry, isopropenyl alcohol can be used as an intermediate for certain drugs, such as the synthesis of antiviral drugs and antibiotics. In the field of pesticides, it is also a precursor substance for certain insecticides and herbicides.

3. Solvents and chemical reagents: Because of its good solubility and high reactivity, isopropenyl alcohol is often used as a solvent and reagent in organic synthesis, especially in reactions that require the introduction of hydroxyl groups or double bonds.

Upstream raw materials

The production of isopropenyl alcohol mainly depends on the following upstream raw materials:

1. Acetone (Acetone) acetone is one of the important raw materials for the production of isopropenyl alcohol. Isopropenyl alcohol can be obtained by reduction or dehydrogenation of acetone.

2. Isopropyl Alcohol (Isopropanol) Isopropenyl alcohol can also be produced by dehydrogenation of isopropyl alcohol. This process is usually carried out at high temperature and pressure, and requires the aid of a catalyst to improve the yield.

3. Propylene (Propylene): Isopropenyl alcohol can be further synthesized by oxidation of propylene to acetone or isopropanol. Propylene, a by-product of petroleum cracking, is in stable supply and relatively inexpensive.

Downstream Products

There are a wide range of downstream products of isopropenyl alcohol, involving many industrial fields:

1. Polymers and copolymers: Isopropenyl alcohol can be polymerized to form polyisopropenyl alcohol or copolymerized with other monomers to form a variety of copolymers with excellent properties, which are widely used in plastics, rubber, fibers and other materials.

2. Fine Chemicals: As an important intermediate, isopropenyl alcohol is used to synthesize a variety of fine chemicals, including pharmaceuticals, fragrances, dyes and surfactants.

3. Solvent: Due to its good solubility, isopropenyl alcohol is widely used in coatings, inks and cleaning agents to improve the performance and stability of these products.

storage method

Isopropenyl alcohol is flammable and volatile, so its storage requires special attention to safety and environmental protection. The following are its main storage methods:

1. Sealed containers: Isopropenyl alcohol should be stored in sealed metal or glass containers to prevent volatilization and external contamination. The container material should have good chemical resistance.

2. Cool and ventilated environment: the place where isopropenyl alcohol is stored should be kept cool and ventilated, away from fire source, heat source and oxidant, so as to avoid the risk of fire or explosion.

3. Anti-static measures: due to the volatility of isopropenyl alcohol, anti-static measures should be taken during storage and use to avoid fires caused by sparks caused by static electricity.

4. Leakage prevention management: in the process of transportation and use should be strictly managed to prevent leakage. If a leak occurs, it should be dealt with immediately and controlled by using adsorbent materials or spraying extinguishing agents.

Safety and environmental protection

The safety and environmental impact of isopropenyl alcohol are important issues in chemical production. Its main safety and environmental requirements include:

1. Health Protection: Operators should wear appropriate protective equipment, such as protective gloves, protective glasses and respirators, to avoid direct contact and inhalation of isopropenyl alcohol vapor.

2. Leakage emergency treatment: in case of leakage, the leakage source should be blocked quickly, personnel should be evacuated, and appropriate adsorption materials should be used for treatment. If necessary, professional emergency rescue team can be called.

3. Waste disposal: The waste generated in the production process should be treated to ensure that it does not pollute the environment. Waste liquid and waste residue shall be recycled or treated according to regulations to avoid direct discharge.

Conclusion

Isoallyl alcohol, as an important chemical raw material, has a variety of applications and broad market prospects. Its production and use of the process need to pay attention to safety and environmental protection, to ensure the provision of quality products to protect personnel health and environmental safety. In the future, with the progress of technology and the increase of demand, the application of isoallyl alcohol in new materials, medicine and high-end chemical industry will continue to expand, and promote the further development of related industries.
