General description

Ammonium sulfate is an ammonium salt commonly used as fertilizer. It can be synthesized by neutralizing sulfuric acid with ammonia. It can enhance the phytotoxicity of several herbicides like glyphosates. Ammonium sulfate is formed as a co-product during the manufacture of caprolactam, a precursor of nylon.

Application

Ammonium sulfate was used in methyl cellulose precipitable tannin assay to evaluate wine tannin in finished wine samples. It was also used in making externally mixed aerosols for analyzing the 1 × 3 tandem differential mobility analyzer (1 × 3-TDMA), which is mainly employed for determining the irreversibility of the hygroscopic growth factor of aerosol particles.
