| Solvents are vital to many industrial reaction processes. They affect reaction rates, chemical equilibria, and the efficiency of heat and mass transfer. The choice of the right solvent is critical not only for a successful chemical transformation but also for the subsequent separation and purification processes. We now report a separable and recyclable polar, aprotic solvent, piperylene sulfone (PS), which combines the excellent reaction medium properties of dipolar, aprotic solvents with the “volatility” of low boiling solvents necessary for facile isolation and purification of products. While piperylene sulfone is not volatile itself, it is readily converted (or “switched”) into volatile species. These volatile species can be collected elsewhere and recombined back into piperylene sulfone for re-use. It is therefore an example of a switchable solvent. |
