Kinetics of Complexation of the Macrocycles 18C6 and 12C4 Ethers with LiAsF6 in 1,2-Dimethoxyethane at 25 deg C.

Abstract

Ultrasonic relaxation spectra of the systems LiAsF6 added to the macrocycles 18C6 or 12C4 ethers, in molar ratio R approx. = 1, in the solvent 1,2-Dimethoxyethane (DME) at t=25 deg C are reported. The concentration range covered was 0.05 to 0.25M for 18C6 and 0.1 to 0.3M for 12C4. Ancillary electrical conductance data reveal that the lithium-macrocycle interaction is weak, the conductance data being the same up to approx. 10 to the -2M, within experimental error of the one for the electrolyte in DME.
