环己胺(CHA)是无色至浅黄色透明液体,有强烈的鱼腥味与氨味,是环己烷环上一个氢被氨基(-NH2)取代的饱和脂环族伯胺。能与水以任意比例混溶,并可与乙醇、乙醚、丙酮、乙酸乙酯、氯仿、庚烷、苯等多数有机溶剂混溶;与水形成共沸物(共沸点 96.4 ℃,含水 55.8 %)。极易吸收空气中 CO2 生成白色结晶的碳酸盐。 |
Cyclohexylamine (CHA) is a colorless to pale-yellow clear liquid with a strong fishy, ammoniacal odor. It is a saturated cycloaliphatic primary amine (one H on the cyclohexane ring replaced by -NH2). Miscible with water in all proportions and with ethanol, ether, acetone, ethyl acetate, chloroform, heptane, benzene and most organic solvents; forms an azeotrope with water (b.p. 96.4 C, 55.8% water). Readily absorbs atmospheric CO2 to form a white crystalline carbonate. |
