n-butanol vs isobutanol
1-Butanol (Cas 71-36-3), also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C4H9OH and a linear structure. Isomers of 1-butanol are isobutanol (CAS 78-83-1), butan-2-ol and tert-butanol.
What Is n-butanol (Cas 71-36-3)?
N-Butanol, with the chemical formula C₄H₁₀O, CAS number 71-36-3, and molecular weight 74.12, is a colorless transparent liquid. At 20°C, n-butanol can dissolve 7.7 parts by mass of water, while water also exhibits a solubility of 20.1 parts by mass in n-butanol. This solvent is mutually miscible with ethanol, diethyl ether, and numerous other organic solvents.
What Is Isobutanol (CAS 78-83-1)?
Isobutanol (IBA), also known as 2-Methyl-1-Propanol, is a colorless, transparent liquid with a distinctive odor. It has extensive industrial applications, including as a solvent, chemical intermediate, and fuel additive.
What are the properties of Isobutanol?
Isobutanol is a flammable liquid whose vapors can form explosive mixtures with air.
It exhibits good solubility, being miscible with ethanol and diethyl ether, and soluble in approximately 20 parts water.
Isobutanol has a boiling point of about 108°C, a melting point of approximately -108°C, and a density of about 0.802 g/cm³.
What is the use of N-butanol?
Production of Plasticizers
n-Butanol serves as a key raw material for manufacturing phthalic acid, aliphatic dicarboxylic acids, and n-butyl phosphate plasticizers, which play a crucial role in plastic and rubber products.
Synthesis of Other Chemicals
Additionally, n-butanol is used as a base material for synthesizing chemicals such as butyraldehyde, butyric acid, butylamine, and butyl lactate.
Extraction and Additives
n-Butanol also plays a vital role in the extraction of oils, pharmaceuticals (such as antibiotics, hormones, and vitamins), and fragrances. It is frequently used as an additive in alkyd resin coatings, serves as a solvent for organic dyes and printing inks, and functions as a dewaxing agent.
Chemical Structure & Identity
| Item | n-Butanol | Isobutanol |
|---|---|---|
| Chemical Name | 1-Butanol | 2-Methyl-1-propanol |
| CAS No. | 71-36-3 | 78-83-1 |
