Ethyl acetate as a polar solvent. I. Conductivities of acids and bases dependent upon the existence of acetylium ions in pure ethyl acetate

A study of the conductivity of the solutions of the Lewis acids SnCl4, TeCl4, TeCl4, AlCl3, SO3, FeCl3, SbCl5, and SbCl3 in ethyl acetate indicates a comparatively high conductivity of the solutions and the formation of compounds possessing high dipole moments. The existence of CH3CO+ is supported by the conductivity of various ansolvo acids. Absence of acetate ions is indicated by the insolubility of metal acetates and low conductivity of the acetates of tertiary bases. Although ethoxides are also insoluble, the existance of CH3CO+ and OC2H5 is supported by conductometric titrations
