Dibenzo-18-crown-6
CAS no: 14187-32-7 Assay: 98% Appearance: red powder Molecular formula: C20H24O6 Molecular weight: 360.4 Melting point: 160~163 degree Solubility Water :Slightly soluble Application:Crown Ether is a macrocyclic polyether whose structure contains hydrogen, carbon and oxygen atoms. Each oxygen atoms are confined between two carbon atoms and exhibits a conformation with a hole (accordingly called "crown"). The common names of Crown Ethers have a prefix to designate the total number of atoms in the cycle and a suffix to designate the number of oxygen atoms in the cycle. For example, 15-crown-5 is composed of 15 atoms in the cycle, 5 of which are O and 10 of which are C. As an ether, crown ethers are soluble in non-polar solvents. They are capable of strong solvency binding cations in their central cavity. The exterior of the ring is hydrophobic. The size of the interior central cavity, fused ring system, and side chains and functional groups determine the solvency capacity of the cation and the power of hydrophobic.
