Acetic acid (C2H4O2) is an organic compound with distinct chemical characteristics and practical advantages. As a weak organic acid, its partial ionization allows gentle participation in acid-base reactions, making it suitable for scenarios requiring precise pH regulation (e.g., food processing, textile dyeing). Meanwhile, the strong corrosiveness of concentrated acetic acid (glacial acetic acid) enables special applications such as industrial cleaning and metal surface treatment. Its high boiling point (118°C) and excellent solvent compatibility (miscible with water and ethanol) ensure stability in high-temperature chemical reactions and material synthesis, serving as a key raw material for producing important chemical intermediates like vinyl acetate and acetic anhydride.
