溶解性:溶于水和乙醇。几乎不溶于醚、苯、氯仿和石油醚光谱特性:MAX ABSORPTION (WATER, PH= 8): 280 NM (LOG E= 2.2), 420 NM (LOG E= 1.8), 500 NM (LOG E= 1.8); SADTLER REF NUMBER: 656 (IR, PRISM); 147 (IR, GRATING)
此外,通过环己烷或环己醇的催化氨解,硝基环己烷还原,以及氢存在下的环己酮催化氨解等方法均可制得环己胺。 精制方法:常含有苯胺和水等杂质。精制时首先将环己胺转变为盐酸盐,用水重结晶,精制后在碱性溶液中用乙醚萃取,固体氢氧化钾干燥,在氮气流中蒸馏。在4.65KPa的压力下精馏,可将苯胺除去。
