What is isopropyl alcohol CAS 67-63-0?
CAS 67-63-0 isopropyl alcohol also known as 2-propanol,isopropanol, IPA, is one of the most common solvents in the world. IPA mixes with most solvents, especially water. IPA is one of the most abundant solvents worldwide, and it is also utilized as a chemical intermediate for most chemical industries.
Properties of isopropyl alcohol
Colorless, transparent liquid with a slight ethanol odor. Miscible with water, ethanol, ether, and chloroform. Its vapor forms an explosive mixture with air, and can ignite and explode upon contact with open flames or high heat. Isopropyl alcohol reacts violently with oxidizers. If exposed to high heat, the pressure inside the container increases, posing a risk of rupture and explosion.
Uses of Isopropyl Alcohol IPA CAS 67-63-0 (Different Purity)
A. Medical & First Aid
Use 70% IPA.
Correct: Disinfecting intact skin before injections, cleaning around a wound.
Incorrect: Pouring directly into open wounds (it damages tissue and delays healing). Use saline or plain water for wound irrigation instead.
B. Electronics & Precision Cleaning
Use 99% IPA.
Correct: Cleaning circuit boards, contacts, removing thermal paste, drying water-damaged devices.
Incorrect: Using any isopropyl alcohol with water (70%, 91%) on live circuits or components.
C. General Household & Lab
Use 70% or 91% IPA.
Correct: Disinfecting surfaces, cleaning glass, removing stickers/adhesive residue, sanitizing tools.
Incorrect: Using on certain plastics (test first), polished wood, or as a general glass cleaner on large windows (it evaporates too fast).
Preparation Methods of isopropyl alcohol
IPA Isopropanol can be prepared by the following two methods:
1. Deoxygenation from propylene: Catalytically hydrogenating propylene at high temperature to produce isopropanol.
2. Reduction from acetone: Reacting acetone with hydrogen in the presence of a catalyst to produce isopropanol.
isopropyl alcohol Precautions:
- Flammability: Highly flammable product. Avoid using near heat sources or flames.
- Consultation: Read the safety data sheet for detailed information.
- Ventilation: Use in a well-ventilated area and keep away from heat sources.
