Introduction

Propanol, also known as isopropanol, is an organic solvent. The following is an introduction to the properties, uses, preparation methods and safety information of propanol:

Quality:

- Propanol is a colorless liquid with the characteristic odor of alcohols.

- It can dissolve water, ethers, ketones, and many organic substances.

Use:

- Propanol is widely used in industry as a solvent in the manufacture of paints, coatings, cleaning agents, dyes, and pigments.

Method:

- Propanol can be prepared by hydrogenation of methane hydrates.

- Another commonly used preparation method is obtained by direct hydrogenation of propylene and water.

Safety Information:

- Propanol is flammable and should be kept away from open flames and high temperatures.

- When handling propanol, wear appropriate protective equipment such as gloves, goggles, and protective clothing.
