reactor. Because of safety concerns and a site limitation on hydrogenation at scale, a continuous flow hydrogenation for the reaction was investigated at lab scale using the commercially available H-Cube. The process was then scaled successfully, generating kilogram quantities on the H-Cube Midi. This flow process eliminated the safety concerns about the use of hydrogen gas and pyrophoric catalysts and also
在开发
苯达莫司汀盐酸盐的新路线时,即在Treanda的A

苯并咪唑中间体5是通过使用间歇反应器对芳族
硝基化合物进行催化多相加氢而生成的。由于安全性考虑和大规模加氢的位置限制,因此使用市售H-Cube在实验室规模下研究了该反应的连续流动氢化。然后成功地扩展了该过程,在H-Cube Midi上产生了千克量。这种流动过程消除了对使用
氢气和发火催化剂的安全隐患,并且还显示出与分批处理相比时空产率提高了1200倍。
