Isopropyl Alcohol (IPA)
(Propan-2-ol)
What is Isopropyl Alcohol (IPA)?
Isopropyl Alcohol (C₃H₈O); commonly known as IPA, Isopropyl Alcohol, or Propan-2-ol, is a colorless, clear, alcohol-like smelling, and flammable liquid. It can form solutions with water, acetone, chloroform, and benzene. It reacts violently with strong oxidizing agents.
IPA has a wide range of applications as a solvent in industry. It is also one of the most commonly used alcohols in household cleaning products, disinfectants, cosmetics, pharmaceuticals, and electronic cleaners.

Isopropyl Alcohol (IPA) – Which Industries Use It?
Isopropyl alcohol (IPA) is a versatile chemical used in many industries. Some of its applications include:
- Chemical Industry: IPA is used as a solvent and is used in the production of many chemical products.
- Cosmetics Industry: IPA is used in makeup products, lotions, perfumes, hair dyes, and other personal care products.
- Medical Industry: IPA is used in the sterilization of many medical devices and for surface disinfection.
- Electronics Industry: IPA is used for cleaning and drying electronic components.
- Automotive Industry: IPA is used to clean unpainted surfaces of vehicles and is also used as an additive for fuel systems.
- Energy Industry: IPA is also used as a solvent in the oil and gas industry, particularly in hydraulic fracturing operations.
In addition to its uses in these industries, IPA is also used in household cleaning products, as antifreeze in freezers and radiators, in the treatment of burns and abrasions, in glass cleaners, and in many other applications.
How is Isopropyl Alcohol (IPA) Produced?
Isopropyl alcohol is produced by the reduction of propylene with hydrogen. The production of isopropyl alcohol is a two-step process.
In the first stage, propylene and hydrogen gas are combined with the aid of a catalyst under high pressure and temperature. As a result of this reaction, propylene reacts with hydrogen to form an intermediate product called isopropyl aldehyde.
In the second stage, isopropyl aldehyde reacts again with hydrogen to form isopropyl alcohol. This reaction is carried out under high pressure and temperature with the aid of a nickel catalyst.
The isopropyl alcohol obtained is subjected to purification and processing steps. These steps may include neutralization with basic substances such as sodium hydroxide or sulfite, distillation, and dehydration. As a result, pure isopropyl alcohol is produced.
