The heating mantle is primarily used for acid reflux because heating some acids directly causes vigorous burning. For example, sulfuric acid. What is the purpose of reflux in distillation? The purpose of reflux in distillation is Non-reflux in which the product formed in vapor form is distilled into another chamber.

One of the most popular and safest methods to heat a reaction mixture is a heating mantle, a resistively heated flexible fiberglass shell that conforms to the shape of the reaction flask. Most heating mantles are hemispherical in design and come in a variety of sizes designed to fit round bottom flasks from 50 mL up to 5000 mL or more.

Reflux heating – interactive simulations – eduMedia. Temperature is one of the kinetic factors most often used to modify the rate of a chemical reaction. Cooler temperatures will slow or stop a reaction. It is the function of the refrigerator that prevents rapid transformation (degradation) of food. Conversely, a higher temperature can often accelerate the reaction rate.

Reflux is a chemistry lab technique that heats a solution, produces vapor, and then condenses and returns the outgoing vapor into its original mixtures. Reflux is widely used in undergraduate organic chemistry labs. Before doing this activity, students should have experience using boiling chips, heating mantles and magnetic stir plates in fume hoods.
