The invention provides an improved process for preparing organic amine borane complex characterized in that it takes advantage of the slow reaction of potassium borohydride with water and the increased solubility in an ether/water mixed solvent containing minor amount of sodium hydroxide, adding slowly an organic amine to control the reaction rate and effectively control the generation of hydrogen gas in a manner to increase the yield and ensure the process safety.
本发明提供了一种改进的有机胺硼氢化物复合物制备工艺,其特点在于利用了氢氧化钾与水反应缓慢及在含少量氢氧化钠的醚/水混合溶剂中的溶解度增加的优点,缓慢地添加有机胺以控制反应速率并有效地控制氢气的生成,从而增加产量并确保工艺的安全性。
