What is tert-Butyl alcohol CAS 75-65-0?

CAS 75-65-0 Tert-butyl alcohol, also known as tert-butanol or 2-methylpropan-2-ol, is a tertiary alcohol with the molecular formula C₄H₁₀O, consisting of a central carbon atom bonded to three methyl groups and a hydroxyl group. It appears as a colorless liquid or crystalline solid with a camphor-like odor, has a melting point of approximately 25.7 °C and a boiling point of 82.4 °C, and is miscible with water, ethanol, and diethyl ether.

 

Formula:

C4H10O

CAS Number:

75-65-0

Also Known As:

2-Methylpropan-2-ol; t-Butyl alcohol; tert-Butanol; t-Butanol; t-BuOH; Trimethyl carbinol; Tertiary butanol; 2-Methyl-2-propanol

 

Tert-Butyl Alcohol TBA

 

What are the applications of tert-Butyl alcohol?

Tert-Butyl alcohol TBA is particularly effective as a denaturant due to its unique properties. When mixed with ethanol, tert-Butyl alcohol disrupts the hydrogen bonding structure of the alcohol, leading to protein denaturation. This alteration removes ethanol's desirable taste and odor, making it unpalatable and harmful if ingested. As a result, denatured alcohol becomes a cost-efficient substitute for pure ethanol in industrial applications, allowing manufacturers to avoid high excise taxes while meeting safety and regulatory standards.

 

CAS 75-65-0 Tert-Butyl alcohol is used as a solvent and ethanol denaturant. It is an active ingredient of paint remover. It acts as an intermediate in the production of methyl tertiary butyl ether and ethyl tertiary butyl ether by reaction with methanol and ethanol.
