A report on Amine, Ammonia and Dimethylamine
Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).
- AmineThis secondary amine is a colorless, flammable gas with an ammonia-like odor.
- DimethylamineSecondary (2°) amines—Secondary amines have two organic substituents (alkyl, aryl or both) bound to the nitrogen together with one hydrogen. Important representatives include dimethylamine, while an example of an aromatic amine would be diphenylamine.
- AmineAmines can be formed by the reaction of ammonia with alkyl halides or with alcohols.
- AmmoniaIn both cases, dimethylamine and trimethylamine are co-produced.

Chemical element with the symbol N and atomic number 7.
Many industrially important compounds, such as ammonia, nitric acid, organic nitrates (propellants and explosives), and cyanides, contain nitrogen.
Many organic functional groups involve a carbon–nitrogen bond, such as amides (RCONR2), amines (R3N), imines (RC(=NR)R), imides (RCO)2NR, azides (RN3), azo compounds (RN2R), cyanates and isocyanates (ROCN or RCNO), nitrates (RONO2), nitriles and isonitriles (RCN or RNC), nitrites (RONO), nitro compounds (RNO2), nitroso compounds (RNO), oximes (RCR=NOH), and pyridine derivatives.
Many saltwater fish manufacture large amounts of trimethylamine oxide to protect them from the high osmotic effects of their environment; conversion of this compound to dimethylamine is responsible for the early odour in unfresh saltwater fish.
Ammonium

Positively charged polyatomic ion with the chemical formula [NH4]+.
It is formed by the protonation of ammonia (NH3).
Ammonium is also a general name for positively charged or protonated substituted amines and quaternary ammonium cations ([NR4]+), where one or more hydrogen atoms are replaced by organic groups (indicated by R).
An example of a reaction forming an ammonium ion is that between dimethylamine, (CH3)2NH, and an acid to give the dimethylammonium cation, [(CH3)2NH2]+:
