AMMONIUM SULFATE
1. GENERAL INFORMATION ID: 7783-20-2
DATE: 18.04.2006
Large quantities of ammonium sulfate are produced by a variety
of industrial neutralization operations required for
alleviation of stream pollution by free sulfuric acid (H2SO4)
as well as in the manufacture of caprolactam.
Ammonium sulfate also is a byproduct of coke oven operations
where the excess ammonia formed is neutralized with sulfuric
acid to form the ammonium sulfate.
