有机胺中的氨基(-NH_2)若氮上的孤对电子不能离域形成共轭体系则此氮呈碱性,可以进行酸碱滴定。海洛因(heroin,即二乙酰吗啡)属于此类物质,利用一种新的
Organic amine amine (-NH_2) if the nitrogen on the lone pair of electrons can not form a conjugate system from the domain, the nitrogen is alkaline, can be acid-base titration. Heroin (diacetylmorphine) belongs to this category and uses a new one
