苄胺
Benzylamine
化合物简介
Benzylamine is an organic chemical compound with the condensed structural formula C6H5CH2NH2 (sometimes abbreviated as PhCH2NH2 or BnNH2). It consists of a benzyl group, C6H5CH2, attached to an amine functional group, NH2. This colorless liquid is a common precursor in organic synthesis and used in the industrial production of many pharmaceuticals. The hydrochloride salt was used to treat motion sickness on the Mercury-Atlas 6 mission in which NASA astronaut John Glenn became the first American to orbit the Earth.

生产方法及用途
生产方法
其制备方法是将乙醇、乌洛托品、氯苄加入反应釜,加热到30~35℃,反应4h,加入盐酸,升温至45~50℃,反应2h,冷却,过滤,滤液升温脱乙醇,改为减压蒸馏,蒸至将干,加碱液,游离出苄胺,常压蒸馏后减压蒸馏得产品。也可用氨解法将氯苄与氢氧化铵、碳酸氢胺加入反应锅,在30~35℃反应6h,静置分出油层,反应液升温赶氨气,于100℃减压蒸馏,然后加入游离碱,分去碱溶液,油层蒸馏得产品。
用途
在显微微晶分析中用以测定钼酸盐、钡酸盐、钨酸盐、钍、锆、铈、镧、镨和钕的沉淀剂。有机分析中用于区别各类羧酸(与羧酸酯类反应生成N-苄胺衍生物,按熔点的不同来区别各种羧酸)。金属有机化合物的定性试验。也用作溶剂、有机合成。
