Chapter 19 Amines(胺) 19.1 Nomenclature In common nomenclature most primary amines are named as alkylamines. In systematic nomenclature they are named by adding the suffix -amine to the name of the chain or ring system to which the nh2 group is attached with elision of the final e Primary amines; 伯胺 CHNH CH3CH2NH2 CH3 CH2 CH2NH, Common name; Methylamine Ethylamine Propylamine IUPAC name; (methanamine)(ethanamine)(Propanamine) 甲胺 乙胺 丙胺
