The invention provides an external micro-interface strengthening system and method for preparing butyl octanol through propylene carbonylation. The system comprises a carbonyl synthesis reactor, the side wall of the carbonyl synthesis reactor is provided with a raw material inlet, the raw material inlet is provided with a micro-interface unit used for dispersing crushed materials into micro-bubbles, and the micro-interface unit comprises a first micro-interface generator and a second micro-interface generator which are sequentially and horizontally connected in series. According to the external micro-interface strengthening system, after the micro-interface unit is arranged at the raw material inlet of the carbonyl synthesis reactor, the problem that in the prior art, the reaction efficiency of the system is low due to the fact that synthesis gas, propylene and a catalyst cannot be fully mixed in the reaction kettle is solved. 本发明提供了一种丙烯羰基化制备丁辛醇的外置微界面强化系统及方法，包括：羰基合成反应器，所述羰基合成反应器的侧壁设置有原料进口，所述原料进口设置有用于分散破碎物料成微气
