The translation of olefin metathesis reactions from the laboratory to process scale has been challenging with traditional batch techniques. In this contribution, we describe a continuous membrane reactor design that selectively permeates the ethylene byproduct from metathetical processes, thereby overcoming the mass-transport limitations that have negatively influenced the efficiency of this transformation
使用传统的批处理技术,将烯烃复分解反应从实验室转换为工艺规模一直具有挑战性。在这一贡献中,我们描述了一种连续膜反应器设计,该设计可选择性地渗透易位过程中的乙烯副产物,从而克服了对分批容器中这种转化效率产生负面影响的传质限制。在二烯丙基丙二酸二乙酯闭环复分解的情况下,膜框式透膜蒸发模块的转换数> 7500。更具挑战性,低效率的底物,环辛烯和14元大环内酯的制备也是有效的。
