Intensified recovery of switchable hydrophilicity solvents in flow

We present an integrated flow chemistry strategy using two membrane-based flow reactors to enhance the extraction and recovery rates of switchable hydrophilicity solvents (SHSs) by five times compared to batch reactors. The developed green flow chemistry strategy achieves an overall single-pass recovery efficiency of 60.1% for 2-(dibutyl amino)ethanol.

Automated summary

In this study, an integrated flow chemistry strategy using two membrane-based flow reactors was developed to enhance the extraction and recovery rates of switchable hydrophilicity solvents (SHSs). The overall single-pass recovery efficiency for 2-(dibutyl amino)ethanol was achieved at 60.1%, representing a significant improvement compared to batch reactors.
