Introduction
N-butanol, also known as butanol, is an organic compound, it is a colorless liquid with a peculiar alcoholic odor. The following is an introduction to the properties, uses, preparation methods and safety information of n-butanol:
Quality:
1. Physical properties: It is a colorless liquid.
2. Chemical properties: It can be dissolved in water and organic solvents, and is a moderately polar compound. It can be oxidized to butyraldehyde and butyric acid, or it can be dehydrated to form butene.
Use:
1. Industrial use: It is an important solvent and has a wide range of applications in the chemical industry such as coatings, inks, and detergents.
2. Laboratory use: It can be used as a solvent to induce helical protein folding, and is often used in biochemical experiments to catalyze reactions.
Method:
1. Butylene hydrogenation: After hydrogenation reaction, butene is reacted with hydrogen in the presence of a catalyst (such as a nickel catalyst) to obtain n-butanol.
2. Dehydration reaction: butanol is reacted with strong acids (such as concentrated sulfuric acid) to generate butene through dehydration reaction, and then butene is hydrogenated to obtain n-butanol.
Safety Information:
1. It is a flammable liquid, avoid contact with the fire source, and keep away from open flames and high temperature environments.
3. It has a certain toxicity, avoid direct contact with the skin and eyes, and avoid inhaling its vapor.
4. When storing, it should be stored in a closed space, away from oxidants and fire sources, and stored at room temperature.
