Rapid chemical reaction workup based on a rigid solvent extraction.

The conventional chemical reaction workup based on liquid-liquid extraction is a time- and labor-consuming practice. We have developed a substantially faster technique for the routine workup that relies on a porous organic polymer (Porelite) supported solvent phase to extract organic products from an aqueous reaction mixture. We call this process rigid solvent extraction. Using this technique, the tedious liquid-liquid extraction can be replaced by a simple filtration, making parallel operation and automation feasible.
