Isopropanol, also known as isopropanol or 2- propanol, is an important solvent and chemical raw material, which is widely used in medicine, cosmetics, coatings, dyes and plastics. Solubility: isopropanol has good solubility and can be dissolved in water and various organic solvents. Solvent: Isopropanol is an excellent general solvent, which can be used to dissolve various organic and inorganic substances, such as resin, paint, ink, essential oil, cosmetics and so on. It is also widely used as a cleaner and disinfectant.
Chemical reaction: Isopropanol can undergo many chemical reactions, such as methylation, esterification and etherification, and is often used in organic synthesis and preparation of other compounds, including drugs, spices and dyes. Disinfectant: Isopropanol is often used as disinfectant because of its antibacterial properties, which can be used to clean and disinfect hands, tools, surfaces and medical devices. Industrial use: Isopropanol is widely used in coatings, inks, dyes, resins, plastics, adhesives, chemicals, fuels and liquid fuel additives.
Medical uses: Isopropanol is often used as cosolvent, diluent and preservative in pharmaceutical preparations. Preparation method: Isopropanol is usually prepared by petrochemical process. The common method is that propane reacts with oxygen in the air at high temperature to generate isopropyl aldehyde (cis-propionaldehyde), and then hydrogenation is carried out to reduce isopropyl aldehyde to isopropanol.
Physical properties: Isopropanol is a colorless liquid, which has a special alcohol taste at room temperature. Its boiling point is 82.4 degrees Celsius and its density is 0.785g/cm? . Safety precautions: Because isopropanol is flammable and volatile, you need to pay attention to safety precautions when using it. Keep away from naked flame and high temperature, and use it in a well-ventilated place. At the same time, avoid contact with strong oxidants to avoid dangerous chemical reactions.
Harm of isopropylation
Combustibility: Isopropanol is a flammable liquid, which can produce flammable vapor. It has a low flash point and explosion limit, so care must be taken to prevent fire and flame when storing and handling isopropanol.
Toxicity: Isopropanol has certain toxicity and can enter the human body through inhalation, skin contact or ingestion. Long-term or high-concentration contact may lead to inhibition and injury of the central nervous system, causing dizziness, nausea, vomiting, tears, oral and throat discomfort and other symptoms.
