You will need to heat the reaction at the boiling point of your solvent(s) and fit a reflux condenser to the RBF. The condenser has cold water flowing through it; the solvent which has evaporated from the reaction will condense on the surface of the condenser and drip back down into the reaction, thus preventing your reaction from drying out.

Jun 25, 2020 · The condenser is mainly used in the distillation process. A distillation is the separation of two liquids by heating. The liquid with the lower boiling point will vaporize first. It is converted back into a liquid inside the condenser. If the condenser deposits the liquid back in the reaction flask, it is called a reflux condenser. Get started

The reflux/take-off condenser consists of a water jacketed tube, the same as described above, assembled with a receiving vessel attached to the lower end of the condenser. Any vapor, such as water from a polymerization reaction, can be condensed and collected in the receiver, from which it can be withdrawn through a bottom valve.

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.

2. Start heating the reaction flask: when heating, ensure good contact between the heating transfer material (water, sand bath, aluminum block, hot plate, etc..) and do not let your reaction reflux to dryness. To prevent your reaction from drying out, ensure that the solvent vapors do not rise higher than the mid-point of the condenser.
