High Quality Global - Premier Isopropyl Alcohol: The Multifaceted Organic Compound-1

Physical and Chemical Properties

Appearance and Odor: It is a colorless transparent liquid with a fragrance similar to that of ethanol.
Solubility: It can be miscible with water, ethanol, ether, acetone, and other organic solvents.
Other Properties: Its molar mass is 60.10 g/mol, density is 0.786 g/mL (at 25℃), melting point is - 89.5℃, and boiling point is 82.3℃. The flash point is 11.7℃.

Application Areas

Solvent: It serves as an excellent solvent for shellac, nitrocellulose, alkaloids, rubber, oils, etc. It is also used in the manufacture of insecticides and glass cleaning agents. Additionally, it can act as an extractant for cottonseed oil and spices.

Raw Material in Organic Chemical Industry: Through various reactions, it can generate a wide range of chemical products such as isopropylamine, methyl isobutyl ketone, methyl isobutyl carbinol, etc. These products are widely applied in industries like pharmaceuticals, pesticides, coatings, and inks.

Pharmaceutical Field: It is a raw material for the production of drugs such as Propranolol, Rifampicin, Pindolol, Diisopropylamine Dichloroacetate, etc. It can be used to extract vitamins and clean medicine capsules. It is often used as a disinfectant for the skin, prostheses, and medical devices, and can also be used for the preservation of biological specimens.

Electronics Industry Field: High - purity isopropyl alcohol is used as a cleaning agent and etchant during the production of semiconductor components and the assembly and processing of very large - scale integrated circuits. It can also be used as a metal degreasing cleaning agent.

Automotive Field: As a fuel additive, it can increase the octane number of gasoline, improving the quality of gasoline. It can also be used as a cleaner for automotive glass, a deicer for windshields, and an anti - fogging agent for aerosol - type windshields.

Preparation Methods

Hydration of Propylene: Currently, the direct hydration of propylene is the main method. Under the action of a catalyst, propylene directly reacts with water through an addition reaction to produce isopropyl alcohol. According to the phase state of the reactants, it can be divided into the gas phase method, gas - liquid mixed phase method, and liquid phase method.

Hydrogenation of Acetone: Under the action of a catalyst, acetone is reduced to isopropyl alcohol in a hydrogen atmosphere. This method has a relatively low reaction temperature, normal pressure, low energy consumption, a simple process flow, and relatively less corrosion to equipment.

Hydrogenation of Isopropyl Acetate: Under the action of a catalyst, isopropyl acetate is hydrogenated to simultaneously produce isopropyl alcohol and ethanol. However, there are many by - products, and the separation of ethanol and isopropyl alcohol is difficult, so it has not been widely applied.

Precautions

The vapor of isopropyl alcohol is irritating to the eyes and skin, and inhalation can be toxic. It belongs to a Class 3 carcinogen. When humans inhale different concentrations of isopropyl alcohol, they will have different reactions. For example, at 400 ppm, it will cause mild irritation to the eyes, nose, and throat, and at 20000 ppm, it will immediately endanger life or health.

Isopropyl alcohol is flammable. Its vapor can form an explosive mixture with air. It can cause combustion and explosion when exposed to open flames and high heat. It should be stored in a cool and ventilated warehouse, away from fire sources and heat sources, protected from direct sunlight, and the container should be kept sealed. It should be stored separately from oxidants.
