Triethylamine as a base
WebTriethylamine is a base, and amines are organic chemistry functional groups with basic nitrogen, a lone pair, and various substituents attached to them.; The parent molecule ammonia is the source of all amines, which can be simply stated as such. To form alkyl amines, three hydrogen atoms in the parent molecule are exchanged for alkyl groups. WebTriethylamine is a base used to prepare esters and amides from acyl chlorides as well as in the synthesis of quaternary ammonium compounds. It acts as a catalyst in the formation of urethane foams and epoxy resins, dehydrohalogeantion reactions, acid neutralizer for condensation reactions and Swern oxidations.
