Accelerated Chemical Reactions and Organic Synthesis
When confronted with this problem, researchers at Purdue University developed a novel approach to reaction acceleration using the Leidenfrost effect. The Leidenfrost effect is a physical phenomenon that occurs when a liquid is brought in close contact with a substance with a temperature that is significantly higher than the liquid's boiling point. This causes an insulating layer of vapor to form, which causes the liquid to levitate and prevents it from rapidly evaporating. This effect, also known as film boiling, accelerates reactions because of interfacial interactions between the heated surface and the reactants. It has the potential to accelerate various organic reactions by a factor of up to 50.
