Hace 3 días · Amines are organic compounds derived from ammonia (NH3) by replacing one or more hydrogen atoms with alkyl or aryl groups. They are characterized by the presence of a nitrogen atom bonded to hydrogen and carbon atoms. The general formula for amines can be written as R3N, where R represents an alkyl or aryl group.
Hace 1 día · Amines are mainly produced by biological activities and are present in the atmosphere and oceans [].Amines originate from animal husbandry [], the food industry [], biomass burning [], and the activities of oceanic phytoplankton [].So far, mostly monoamines, such as monomethylamine (MMA), dimethylamine (DMA), diethylamine (DEA), and trimethylamine (TMA), are measured, which have strong and ...
