Oxidation of Amines to Nitroso Compounds
Oxidation of Amines to N-Nitrosamines: Industrial Applications
Among other uses, N-nitrosamines are being used in rubber manufacturing.
Additionally, N-nitrosamines are being generated as unwanted by-products during the use of cooling lubricants which contain amines as emulsifiers. The amines react with nitrite in the coolant to N-nitrosamines. The nitrite could be formed, for example, by a bacterial reaction of nitrates in the coolant. Furthermore, under the extreme conditions under which cooling lubricants are used, oxidation of air nitrogen leading to nitration has to be taken into consideration.
