This document discusses ammonia and its derivatives such as amines and amides. It describes the manufacturing process of ammonia through combining nitrogen and hydrogen at high temperature and pressure using an iron catalyst. Ammonia is widely used to produce fertilizers, explosives, and other chemicals. Controls for ammonia emissions include wet scrubbers and condensation to address its toxicity issues. The document also covers polymerization methods like bulk, solution, suspension and emulsion polymerization as well as different types of copolymers.
