Importance of refluxing in organic chemistry
Witryna6 paź 2016 · The health concerns of acetonitrile, dimethyl sulfoxide, and acetone are largely not going to pose a hazard for a laboratory experiment. All three of these can likely be found in any organic teaching lab. Cost comparison, from Sigma Aldrich: Acetonitrile: 2 L = $172.50. Dimethyl sulfoxide: 2 L = $208.50. Acetone: 2 L = $94.80. WitrynaRefluxing is used in organic compounds because they have weak boiling points and can be volatile or evaporate quickly into the air. Thus, for the prevention of liquid loss, the …

Q: Explain the regiochemistry of the Friedel … WitrynaRefluxing is a technique that constantly condenses the vapor and returns it to the flask. This allows reactions to be performed at high temperatures, such as at the solvent's boiling point, without losing the solvent to evaporation. Refluxing is achieved with a special piece of glassware called a condenser, which is attached directly to your flask.
