Chinese high-quality isopropanol supplier 99.9% Isopropyl Alcohol/ipa

1、 Basic Information
Chinese name: Isopropanol
English name:
iso-Propyl alcohol；
isopropanol；
Dimethylcarbinol；
2-Propanol
Alias: Dimethylmethanol, 2-propanol, also known as IPA in the industry
chemical formula:
C3H8O；
(CH3)2CHOH
Molecular weight: 60.095 (or 60.10, slightly different depending on the calculation method)
CAS number: 67-63-0
EINECS number: 200-661-7
2、 Physical properties
Appearance and characteristics: Colorless and transparent liquid, with a smell similar to a mixture of ethanol and acetone
Melting point: -88.5 ℃ (some sources also provide -89 ℃ or -89.5 ℃, which may be due to differences in measurement conditions or accuracy)
Boiling point: 82.45 ℃ (there are also data indicating 82.3 ℃ or 82.6 ℃, which may also be due to differences in measurement conditions or accuracy)
Relative density (water=1): 0.7855 (or 0.786g/mL, at room temperature)
Solubility: soluble in most organic solvents such as water, alcohol, ether, benzene, chloroform, but insoluble in salt solutions
Isopropanol also has some unique physical properties, such as lower melting and boiling points, lower relative density, and becoming increasingly viscous with decreasing temperature.
These properties give isopropanol unique advantages in industrial applications.

3、 Chemical properties
Flammability: Flammable, its vapor can form explosive mixtures with air, with an explosive limit of 2.0% to 12% by volume
Reactivity: Can participate in various chemical reactions, such as esterification, etherification, oxidation, etc
Oxidation reaction: can be oxidized to acetone, and the reaction requires the presence of a catalyst
Dehydration reaction: Isopropene is produced through dehydration reaction, which also requires the presence of a catalyst
Reaction with bromine: Reacts with bromine in a complex manner, mainly producing acetone bromide such as BrCH ₂ COCBr ∝ and isopropyl bromide
4、 Industrial use
Isopropanol, as an important chemical product and raw material, has a wide range of uses:

Organic raw materials and solvents: can be used for the production of acetone, hydrogen peroxide, methyl isobutyl ketone, diisobutyl ketone, isopropylamine, isopropyl ether, isopropyl alcohol ether, isopropyl chloride, as well as fatty acid isopropyl ester and chlorinated fatty acid isopropyl ester.
Meanwhile, as a solvent, it can be used in the production of coatings, inks, extractants, aerosols, etc.
Antifreeze, cleaning agent, etc.: can be used as antifreeze, cleaning agent, additive for blending gasoline, dispersant for pigment production, fixative for printing and dyeing industry, anti fog agent for glass and transparent plastics, etc.
Pharmaceuticals, pesticides, etc.: In the field of fine chemicals, it can be used to produce isopropyl nitrate, isopropyl xanthate, triisopropyl phosphite, aluminum triisopropoxide, as well as pharmaceuticals and pesticides.
Cleaning and degreasing agent: In the electronics industry, isopropanol is commonly used as a cleaning and degreasing agent, such as for cleaning discrete devices and medium to large-scale integrated circuits.
Other uses: It can also be used for the production of diisopropyl acetone, isopropyl acetate, and thymol.
In addition, isopropanol can also be used as a diluent for adhesives, an extractant for cottonseed oil, and a solvent for nitrocellulose, rubber, coatings, cordyceps, alkaloids, oils, etc.
