Refluxing is different from boiling in that
WebMade a post earlier about refluxing a rxn with toluene as my solvent. Every time I come back in the morning, it’s all gone. I’ve used PFTE paste, Teflon stopcocks, normal silicon grease, glass stoppers. NOTHING works, it somehow gets thru the tiniest of cracks. The condenser is on, and legit I see no droplets or condensation, even on the ... WebThe primary difference between a distillation and reflux setup is the purpose of the experiment. Distillation setups are used for separating the components of a mixture based on their boiling point, while reflux setups are used for purification of the initial solution by separating impurities from the liquid and for synthesis of new solutions.

There, it condenses on the … WebSolubility of many compounds (excluding gasses) is far higher near the boiling point of a mixture. As the reaction usually takes place based on two dissolved species, the reaction rate is higher. Also, more homogenous solutions give generally more homogenous results/products. So operation near the boiling point of a solution is often preferred.
