New Condensers Cool Solvent Without Flowing Water
In a single reaction, synthetic chemists sometimes can run through hundreds of liters of water, possibly without realizing it. The culprit is their solvent condenser, a piece of glassware that uses flowing water to cool solvents refluxing in a reaction vessel. Now two groups of chemists have invented condensers that use little or no water to condense boiling solvents.
A typical condenser consists of a glass tube nested within another. Water flows between these two . . .
