Application

Ammonium acetate is widely used in the dyeing and printing of textiles to promote good leveling of the dyestuff on the fabric. It is often used in dye baths in conjunction with acids and other salts.

Ammonium acetate is also used in the manufacture of antibiotics and other pharmaceutical products, and in the surface treatment of metals. It can also be used in a number of organic reactions, as a (e.g. in the production of foam rubber), in the production of vinyl plastics, and in the manufacture of industrial detergents.
