Chemistry B11 Bakersfield College Chemistry B11 Chapters 14 Amines, aldehydes, ketones and carboxylic acids Amines: are derivatives from ammonia (NH3). Aliphatic amines: an amine in which nitrogen is bonded only to alkyl group or hydrogens. Aromatic amines: an amine in which nitrogen is bonded to one or more aromatic rings. Note: amines are classified as primary ( 1), secondary .

Naming aromatic amines 17.4 Isomerism for Amines Constitutional isomerism in amines can arise from several causes. Different carbon atom arrangements produce isomers and Different positioning of the nitrogen atom on a carbon chain is another cause for isomerism. In secondary and tertiary amines, different partitioning of carbon atoms among the

We have already seen the reaction of various amines with ketones and aldehydes to generate imines and their analogues. E.g.

chemical sources, sinks of ozone, and the precursors of particulates. The Regional Atmospheric Chemistry Mechanism (RACM2) is a gas-phase chemical mechanism that is widely used for the modeling of regional atmospheric chemistry (Stockwell, et. al., 2013). It uses a lumped molecular approach for representing atmospheric chemistry.

Chemical Solvent Mechanism – The absorption reactions for the amine-based CO 2 capture system can be broken into two reac-tions, as given below. The absorption of CO 2 by primary and secondary amines (SC1) is mainly dictated by the formation of carbamates. The reaction of CO 2 with tertiary amines (SC2) results in the formation of a bicarbonate.
