Acetic acid is an important organic chemical raw material, which is widely used in various fields, especially in the field of chemical production raw materials. Acetic acid has a wide range of properties and uses, which will be described in detail below.

1. the properties of acetic acid

1. physical properties
acetic acid is a colorless and transparent liquid with a pungent odor. It has a melting point of 16.7°C, a boiling point of 117.9°C and a density of 1.049g/cm³. Acetic acid is easily soluble in water and can be miscible with many organic solvents.

2. chemical properties of
acetic acid is acidic, is a weak acid. It can react with bases to form salts and water, or with metals to form hydrogen and the corresponding metal acetates. In addition, acetic acid is also reductive and can be oxidized to carbon dioxide and water.

2. the use of acetic acid

1. Production of acetate fiber
Acetic acid can be used to produce acetate fiber, which is a kind of man-made fiber with good air permeability and moisture absorption, and is widely used in the production of clothing, textiles, etc.

2. Production of ethyl acetate
Acetic acid can react with ethanol to produce ethyl acetate, which is an important organic solvent and is widely used in coatings, inks, adhesives and other fields.

3. Production of acetate
Acetic acid can react with alkali to generate a variety of acetates, such as sodium acetate, potassium acetate, these acetates are widely used in food, medicine, chemical and other fields.

4. Production of other chemicals
Acetic acid can also be used to produce many other chemicals, such as acetic anhydride, ammonium acetate, etc.

In conclusion, acetic acid has a wide range of applications in the field of chemical production raw materials, is an important organic chemical raw materials.
