Application of 33100-27-5, An article , which mentions 33100-27-5, molecular formula is C10H20O5. The compound – 1,4,7,10,13-Pentaoxacyclopentadecane played an important role in people’s production and life.
Conductance studies have been performed on acetonitrile solutions of LiI, NaBPh4, and KBPh4 at difference concentrations of 12-crown-4, 15-crown-5, 18-crown-6, and TM-12-crown-4.Upon the addition of these crown ethers to the LiI solutions, the equivalent conductance increases.A decrease is observed for similar experiments with NaBPh4 and KBPh4 solutions.Infrared studies were performed in the 500-200 cm-1 region, leading to the unambiguous conclusion that the crown ethers are complexing the lithium cation.A model for the solvation of the lithium ion is proposed to account or the increase in conductance found for the lithium salts.Since a 1:1 solid complex is isolated from the acetonitrile solutions containing LiBr and 12-crown-4 or 15-crown-5, the composition of the complexes in solution is assumed to be 1:1.Analysis of the conductance data at different mole ratios of crown ether to salt provides equilibrium constants for the 1:1 association complex.For the lithium cation these are in the order: Keq(12-crow-4) < Keq(15-crown-5) < Keq(18-crown-6), whereas for the sodium cation Keq(12-crown-4) << Keq(15-crown-5).
