Melamine resin contains melamine in a manner similar to table salt containing chlorine. While melamine is dangerous to ingest, melamine resin is not. Melamine is the chemical that has been contaminating pet-food lately. Melamine resin is the thermoplastic from which plastic-ware, counter-tops, etc are made.
Methylamine is an organic compound with a formula of CH 3 NH 2. This colorless gas is a derivative of ammonia, but with one H atom replaced by a methyl group.It is the simplest primary amine. It is sold as a solution in methanol, ethanol, THF, and water, or as the anhydrous gas in pressurized metal containers.Industrially, methylamine is transported in its anhydrous form in pressurized railcars and tank trailers.ethylamine is prepared commercially by the reaction of ammonia with methanol in the presence of a silicoaluminate catalyst. Dimethylamine and trimethylamine are coproduced; the reaction kinetics and reactant ratios determine the ratio of the three products.
