1. Acetic acid is one of the most important organic acids. It is mainly used in the production of acetic anhydride, acetate and    cellulose acetate.

2, can be used in some pickling and polishing solution, in the weak acidic solution as buffer (such as galvanized, electroless nickel plating), in the semi-bright nickel plating electrolyte as an additive, in the passivation solution of zinc, cadmium can improve the passivation film binding force, and commonly used to adjust the pH of weak acid plating solution.

3, used for the production of acetate, such as manganese, sodium, lead, aluminum, zinc, cobalt and other metal salt, widely used as catalyst, fabric dyeing and leather tanning industry additives.

4, can be used as an analytical reagent, organic synthesis, pigment and drug synthesis.

5. In the food industry, acetic acid is used as an acidifier.
