Application

Kann als Phasentransferkatalysator eingesetzt werden.

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

Makrozyklische Polyether mit sich wiederholenden (-CH₂CH₂O) Einheiten. Die Verbindungen sind ionophor (bilden stabile Komplexe mit Kationen).

Phase transfer catalyst, complexing-agent[1]
