1.3K: Reflux - Chemistry LibreTexts

Aug 18, 2019 · Overview of Reflux. A reflux setup (Figure 1.58) allows for liquid to boil and condense, with the condensed liquid returning to the original flask. A reflux setup is analogous to a distillation, with the main difference being the vertical placement of the condenser. The liquid remains at the boiling point of the solvent (or solution) during active reflux.

Catalytic distillation - Wikipedia

Catalytic distillation - Wikipedia

Catalytic distillation is a branch of reactive distillation which combines the processes of distillation and catalysis to selectively separate mixtures within solutions. Its main function is to maximize the yield of catalytic organic reactions, such as the refining of gasoline.The earliest case of catalytic distillation was thought to have dated back to 1966; however, the idea was officially .
