설명

일반 설명

Methanol is a polar solvent and feedstock to produce chemicals and fuel additives. It can be produced through the catalytic hydrogenation of CO₂.

애플리케이션

Methanol can be used as a solvent in the:

• Palladium(II)-exchanged hydroxyapatite-catalyzed Suzuki–Miyaura cross-coupling reactions.
• Reductive amination of ketones with ammonia and dihydrogen to synthesize primary amines.
