異丙胺(簡寫IPA、MIPA)是一種有機化合物,化學式為C3H9N,它是具有氨味的無色吸濕性液體,可燃。它是重要的化工中間體。[3]
合成
異丙胺可由異丙醇和氨氣在氫氣的存在下,以氧化鋁負載的氧化銅、氧化鎳催化劑催化,在180~220 °C、30~60 bar下反應得到:[4]
性質
異丙胺可以和醛發生縮合反應,如和苯甲醛反應,生成N-亞苄基異丙胺;[6]它也能和醯氯反應,如和聯苯-4,4'-二甲醯氯在三乙胺的存在下反應,生成N,N '-二異丙基聯苯-4,4'-二甲醯胺。[7]
- C3H9N + HNO3 → [C3H9NH]NO3
- C3H9N + HCOOH → [C3H9NH]HCOO
