Abstract

Impact in Continuous flow Heated Mechanochemistry (ICHEM) was used for the production of solketal at 60 °C using glycerol and acetone in the presence of homogeneous FeCl₃.6H₂O (1 mol%). In our optimized conditions, the target compound was obtained in 96% yield (conversion of 97% and selectivity of 99%) with a productivity of 276 g day^–1 with a 80 mL continuous flow reactor. This new technology combines beads mechanochemistry and continuous flow and offers: (i) a better mixing of the two unsoluble parts (glycerol and acetone) by reducing the viscosity of the feed stream and (ii) an alternative of the single-screw and double-screw extruders which are unefficient with a liquid reaction media.

对连续流加热机械化学技术的影响：一种改进的溶剂合成方法

采用连续流动冲击加热机械化学（ICHEM）方法，在60℃条件下，以均匀的FeCl3.6H2O （1mol %）存在下，以甘油和丙酮为原料制备索酮。在优化条件下，在80 mL连续流反应器中，目标化合物的收率为96%（转化率为97%，选择性为99%），产率为276 g day-1。这项新技术结合了微珠机械化学和连续流动，提供了：(i)通过降低进料流的粘度，更好地混合了两种不溶性成分（甘油和丙酮）；（ii）替代了单螺杆和双螺杆挤出机，这两种挤出机在液体反应介质中效率不高。图形抽象
