What are the properties of isopropyl alcohol? CAS 67-63-0 Physical/Chemical Properties

Isopropyl alcohol (IPA; CAS No.: 67-63-0) is one of the most widely used industrial solvents and disinfectants. Renowned for its rapid evaporation rate and potent cleaning capabilities, isopropanol plays a pivotal role in fields such as pharmaceuticals, electronics, cosmetics, and chemical manufacturing.

Physical and Chemical Properties of Isopropyl alcohol Explained

Understanding Alcohols:

Alcohols are a class of organic compounds characterized by the presence of one or more hydroxyl groups (―OH) attached to carbon atoms within an alkyl group (i.e., a hydrocarbon chain). Alcohols can be viewed as organic derivatives of water-specifically, as water molecules in which one hydrogen atom has been replaced by an alkyl group; in organic structural formulas, the alkyl group is typically represented by the symbol R. For instance, in ethanol (also known as alcohol), the alkyl group is the ethyl group (―CH2CH3).

Physical Properties of Isopropyl Alcohol (CAS 67-63-0):

CAS 67-63-0 Isopropanol is highly volatile, flammable, and possesses a low boiling point; furthermore, it is completely miscible with water and various organic solvents. Consequently, it is well-suited for rapid-drying applications and requires storage in a tightly sealed container.

Chemical Properties of 2-propanol:

Under standard temperature and pressure, isopropyl alcohol (IPA) exhibits chemical stability; however, it undergoes reactions under specific conditions:

1. Oxidation Reactions

Isopropyl alcohol liquid can be oxidized to form acetone:

C₃H₈O + [O] → C₃H₆O + H₂O

This characteristic is widely utilized in industrial chemical synthesis.

2. Combustion Reactions

When isopropyl alcohol burns, it produces carbon dioxide and water:

C₃H₈O + O₂ → CO₂ + H₂O + Heat

This reaction releases a significant amount of thermal energy; consequently, in certain applications, IPA serves as an effective fuel.

3. Dehydration Reactions

Under strongly acidic conditions, isopropanol undergoes dehydration to yield propylene-an important petrochemical intermediate.

4. Reactivity

It reacts with strong oxidizing agents (posing a risk of fire or explosion).
Under catalytic conditions, it reacts with acidic substances to form esters.
It remains chemically stable under neutral conditions.

Isopropanol IPA Safety & Handling Requirements

Liquid isopropyl alcohol is highly volatile and flammable; therefore, it must be kept away from heat sources, sparks, and open flames. To ensure safe handling, it should be used in a well-ventilated environment; when stored, it must be kept tightly sealed, and the inhalation of excessive vapors should be avoided.
