CAS 75-65-0 Tert-butyl alcohol is the simplest tertiary alcohol, with a formula of (CH₃)₃COH. It is one of the four isomers of butanol. tert-Butyl alcohol is a colorless solid, which melts near room temperature and has a camphor-like odor.
Is tert-Butyl alcohol (TBA CAS 75-65-0) a strong acid?
No, tert-butyl alcohol is a very weak acid. It is classified as a tertiary alcohol, and its hydroxyl proton is only slightly ionizable in aqueous solutions.
Tert-butyl alcohol TBA has the molecular formula C₄H₁₀O and a molecular weight of 74.12 g/mol. It appears as a colorless liquid or crystalline solid at room temperature, possessing a mild camphor-like odor. Due to its relatively high melting point, it exists as a solid below 25.7 °C and as a liquid above this temperature, with a boiling point of 82.4 °C. Liquid Tert Butanol exhibits a density of 0.786 g/cm³ at 20 °C and a refractive index of 1.387. These optical and volumetric properties reflect its non-aromatic, branched structure, which influences light refraction and mass distribution in the liquid phase.
CAS 75-65-0 tert-butyl alcohol Uses
Tertiary butyl alcohol (TBA) is a good solvent for many organic compounds, and it is used in a variety of industrial and laboratory applications. TBA is also used to produce other chemicals, such as methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE), which are used as gasoline additives.
Toxicology
Human exposure may occur due to fuel oxygenate metabolism. Tert-butanol is poorly absorbed through skin but rapidly absorbed if inhaled or ingested. Tert-butanol is irritating to skin or eyes. Toxicity of single doses is usually low but high doses can produce a sedative or anesthetic effect.
