A reflux condenser allows running a reaction at a higher temperature while minimizing the loss of solvent. The reflux condenser is a specially made piece of glassware with a cooling water jacket that condenses solvent vapor, returning it to the reaction flask
This material is prepared using a heated centrifuge in a spin casting head. Before starting material preparation, pre-heat the spin casting head to 60 ~ 65oC.
The first step is preparation of the catalyst solution and reaction solution
Setting up a reflux condenser is relatively simple, with the biggest concerns being stable water supply and leaks at the connections.
