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