General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

Can be useful as phase-transfer catalysts.
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.

Other Notes

Macrocyclic polyethers with repeating (-CH2CH2O) units. The compounds are ionophoric (form stable complexes with cations).
Phase transfer catalyst, complexing-agent
