What is 2-Methyl-2-propanol (tert-Butanol)?

2-Methyl-2-propanol, commonly known as tert-butanol (t-BuOH) or tertiary butanol, is a colorless, flammable liquid alcohol. It's a tertiary alcohol, meaning the carbon atom bonded to the hydroxyl (-OH) group is also bonded to three other carbon atoms. This unique structure significantly impacts its properties and reactivity. Understanding its chemical characteristics is crucial to appreciating its diverse applications.

Chemical Properties of 2-Methyl-2-propanol

Molecular Formula: C₄H₁₀O
Molar Mass: 74.12 g/mol
Melting Point: 25.5 °C (77.9 °F)
Boiling Point: 82.2 °C (180 °F)
Solubility: Miscible with water, ethanol, and diethyl ether.
Flammability: Highly flammable.

Its relatively high melting point compared to other alcohols of similar size is attributed to its strong intermolecular hydrogen bonding. This also contributes to its good solubility in water. The tertiary structure also influences its reactivity; it's less prone to oxidation compared to primary or secondary alcohols.

Synthesis of 2-Methyl-2-propanol

2-Methyl-2-propanol is primarily produced industrially through two main methods:

Hydration of Isobutene: This is the most common method, involving the addition of water to isobutene in the presence of an acid catalyst. This process is highly efficient and produces high yields of tert-butanol.
Indirect Hydration: This method involves the formation of an intermediate compound, which is then hydrolyzed to produce tert-butanol.

The choice of synthesis method depends on factors like cost, available resources, and desired purity.
