Structure and Properties[edit | edit source]
2-Methylbutan-1-ol is a primary alcohol with a branched structure. The molecule consists of a four-carbon chain with a methyl group attached to the second carbon and a hydroxyl group (-OH) attached to the first carbon. This structure gives it the IUPAC name 2-methylbutan-1-ol.
The compound is a colorless liquid at room temperature with a characteristic alcohol odor. It has a boiling point of 128 °C and a melting point of -117 °C. Its density is 0.805 g/cm³, and it is slightly soluble in water, but more soluble in organic solvents such as ethanol and diethyl ether.
Synthesis[edit | edit source]
2-Methylbutan-1-ol can be synthesized through the hydroformylation of isobutene followed by hydrogenation. This process involves the addition of a formyl group (CHO) to isobutene to form 2-methylbutanal, which is then reduced to 2-methylbutan-1-ol.
Applications[edit | edit source]
2-Methylbutan-1-ol is used in the manufacture of esters for the flavor and fragrance industry. It is also used as a solvent in various chemical reactions and as an intermediate in the synthesis of other compounds.
