Acetic Acid: Properties, Applications, and Technical Data
Acetic acid is a colorless liquid with a pungent odor, commonly used in various industrial and laboratory applications. In this article, we will discuss the properties, applications, and technical data of acetic acid.
PROPERTIES
Acetic acid has a chemical formula of CH3COOH, a boiling point of 118.1 °C, and a melting point of 16.6 °C. It is a weak organic acid and is highly soluble in water and most organic solvents. Acetic acid is flammable and can form explosive mixtures with air. Its density is approximately 1.05 g/mL at standard conditions.
APPLICATION
Acetic acid is widely used in various industries, including food, pharmaceuticals, and chemical manufacturing. In the food industry, acetic acid is used as a preservative, flavoring agent, and pH control agent. In the pharmaceutical industry, acetic acid is used as a solvent for various drugs and as a raw material in the production of various chemicals, such as acetic anhydride and vinyl acetate. Additionally, acetic acid is used in the production of various chemicals, such as esters, cellulose acetate, and polyvinyl acetate.
TECHNICAL DATA
To ensure the safe use of acetic acid in industry and laboratory settings, various technical data have been established for its production, handling, and use. The following are the technical data for acetic acid:
Purity: The purity of acetic acid used in industry must be greater than 99%. Impurities such as water, alcohols, and other organic acids can affect the performance of acetic acid and increase the risk of contamination.
Moisture Content: The moisture content of acetic acid should be less than 0.3% by weight to prevent corrosion in handling and storage equipment.
Acid Content: The acid content of acetic acid should be less than 0.05% by weight to prevent corrosion in equipment and maintain product quality.
Residue after Evaporation: The residue after evaporation of acetic acid should be less than 0.01% by weight to prevent blockage of handling and storage equipment.
Flash Point: The flash point of acetic acid is 39.2 °C. This value should be monitored to ensure safe handling and storage of acetic acid.
