What is 2-methyl-1-propanol (isobutanol)?
2-methyl-1-propanol (isobutanol) is a colorless, flammable organic compound with a peculiar odor. It exists in three isomers: n-butanol, sec-butanol and tert-butanol. Because it belongs to the alcohol group, isobutanol is often used as a solvent in chemical reactions and is also an important raw material for organic synthesis.
Physical Properties Of 2-methyl-1-propanol (isobutanol)
- Appearance: colorless transparent liquid with special odor.
- Melting point:-108℃
- Boiling point:107.9℃
- Density:0.803g/cm³
- Flash point:27.8℃
- Refractive index:1.393
- Solubility:Slightly soluble in water, also soluble in about 20 times of water (at 20℃), soluble in ethanol and ether.
- Volatility: has a certain degree of volatility.
Chemical Properties Of 2-methyl-1-propanol (isobutanol)
- Flammability: flammable, its vapor and air can form explosive mixtures, when exposed to open flame, high heat can cause combustion and explosion.
- Reactivity: it can react strongly with oxidizing agents, and decompose with heat to release toxic gases.
- Raw material for organic synthesis: Isobutanol is an important raw material for organic synthesis, and can be used to manufacture many chemical products, such as petroleum additives, antioxidant 2,6-di-tert-butyl-p-cresol, isobutyl acetate (paint solvent), and so on.
Is 2-methyl-1-propanol (isobutanol) an Alcohol?
Yes.
2-Methyl-1-propanol is classified as an alcohol because its molecular structure contains a hydroxyl group (–OH) bonded to a saturated carbon atom. This functional group defines alcohols in organic chemistry and gives isobutyl alcohol its characteristic chemical behavior, such as hydrogen bonding, moderate polarity, and reactivity with acids and oxidizing agents.
From a chemical classification standpoint, it is a primary alcohol, meaning the –OH group is attached to a carbon atom connected to only one other carbon atom.
What is 2-methyl-1-propanol (isobutanol) used for?
Isobutanol (IBA) is an organic synthetic raw material used in the manufacture of petroleum additives, the antioxidant 2,6-di-tert-butyl-p-cresol, Isobutyl acetate (paint solvent), plasticizers, synthetic rubbers, synthetic musks, essential oils of fruits and synthetic drugs.
How to store 2-methyl-1-propanol (isobutanol)?
- Isobutanol (IBA) should be stored in a cool, well-ventilated, dry environment, away from fire and heat sources.
- It must be kept in tightly sealed metal containers and isolated from oxidizing agents, acids, and strong alkalis.
