Uses and synthesis of Acetic acid liquid

Acetic acid liquid, commonly known as AcOH, is one of the most important fatty acids because it is the main component of vinegar. In nature, it is generally present in many plants in the form of free form or ester. Molecular formula CH3COOH. Acetic acid is a colorless liquid and has irritating taste. The melting point is 16.6℃, the boiling point is 117.9℃, and the relative density is 1.049(20/4℃). Soluble in water, ethanol, glycerin, ether and carbon tetrachloride; Insoluble in carbon disulfide. Anhydrous acetic acid solidifies into ice form at low temperature, commonly known as glacial acetic acid. Acetic acid is corrosive. It is a weak organic acid with acid commonness and can be esterified with alcohols.

Applications/Functions of Acetic acid liquid

• Acetic acid liquid is mainly used to produce acetic anhydride, vinyl acetate, acetate, metal acetate, chloroacetic acid, cellulose acetate, and as a solvent
• Acetic acid is used to synthesize vinyl acetate, acetate fiber, acetate, metal acetate, and halogenated acetic acid. It is also an important raw material for the synthesis of pharmaceuticals, dyes, pesticides, and organic acids
• Acetic acid is commonly used as an acetic acid assay, general purpose and non-aqueous titrating solvent, and chromatographic assay agent, as well as in organic synthesis
• The Acetic acid liquid can be used as a acetic acid agent in compound seasonings and in vinegar, cans, jellies, and cheese in modest quantities according to production requirements. It can also compose the aroma enhancer of incense wine, the amount of use is 0.1 ~ 0.3g/kg.

Physicochemical Property of Acetic acid liquid

Acetic acid colorless clear liquid has pungent smell. Miscible with water, ethanol, benzene and ether, insoluble in carbon disulfide.

Production methodprocess of Acetic acid liquid

The liquid phase catalytic oxidation is usually carried out with butane as raw material, acetic acid as solvent, cobalt acetate as catalyst and air as oxidant at 170 ~ 180℃ and 5.5MPa. It can also be 30 ~ 100℃ light oil as raw materials. The Acetic acid was separated by 6 columns.
