  • 概述:异丁醇又名异丙基甲醇、2-甲基丙醇,具酒精味的无色可燃液体,是茶鲜叶、红茶和绿茶香气的主要成分之一,分子量74.12。沸点107.66℃。相对密度0.8016 (20/ 4℃)。折射率1.3959。闪点37℃。能与醇、醚混溶,微溶于水。其蒸气可与空气形成爆炸性混合物,爆炸极限为2.4% (体积) 。能与氯化钙形成加成化合物(CaCl2·3C4H10O)。可将合成甲醇的副产物再进行精馏而得,也可由粗制杂醇油中分镏得到。工业上以羰基钴为催化剂,使丙烯和一氧化碳与氢的混合物在110~140℃,2.0265×107~3.0397×107Pa下反应,生成丁醛和异丁醛,然后催化氢化、分离即得异丁醇。用于制造石油添加剂、抗氧剂、增塑剂、合成橡胶、人造麝香、果子精油和合成药物。也用作溶剂和化学试剂。
