Description

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.It is generally used as a phase transfer catalyst and a complexing agent. It specifically binds to potassium ion, ammonium or protonated alkyl amines to form complexes.

Can be useful as phase-transfer catalysts.

Other Notes

Macrocyclic polyethers with repeating (-CH₂CH₂O) units. The compounds are ionophoric (form stable complexes with cations).

Phase transfer catalyst, complexing-agent
