We describe a promising method for the continuous hydrogenation of alkenes or alkynes by using a newly developed fine-bubble generator. The fine-bubble-containing slug-flow system was up to 1.4 times more efficient than a conventional slug-flow method. When applied in the hydrogenation of phenols to the corresponding cyclohexanones, the fine bubble–slug-flow method suppressed over-reduction. As this method does not require the use of excess gas, it is expected to be widely applicable in improving the efficiency of gas-mediated flow reactions.

多键和酚的细泡-段塞流氢化

我们描述了一种使用新开发的细气泡发生器连续氢化烯烃或炔烃的有前途的方法。含细气泡的段塞流系统的效率比传统的段塞流方法高 1.4 倍。当应用于苯酚加氢生成相应的环己酮时,细泡-段塞流法抑制了过度还原。由于该方法不需要使用过量气体,因此有望广泛应用于提高气体介导流动反应的效率。
