Application
18-Crown-6 can be used as a model for crown ethers to study the effect of acid-base properties of mixed solvent on their solution enthalpy.[1]It is generally used as a phase transfer catalyst[2] and a complexing agent.[3] It specifically binds to potassium ion,[4] ammonium or protonated alkyl amines to form complexes.[5]
Can be useful as phase-transfer catalysts.
