Ethyl acetate as a polar solvent. II. Formation of acids and bases due to solvation of proton in ethylacetate

Abstract

Conductivities of the solutions of a number of protonic acids in ethyl acetate plotted against the composition of the solutions indicate the formation of 1:1 compounds. Their dipole moments indicate a very high polarity. This has been explained by proposing the formation of compounds of the type CH₃COOC₂H₅ · H⁺ · A^-. The conductivity of the solutions of tertiary bases has been explained on the basis of the formation of compounds of the type (CH₂COOC₂H₅)^-BH⁺. Conductometric, potentiometric, and titrations using visual indicators to detect the end point have been carried out to confirm the autoprotolysis of ethyl acetate as 2 CH₃COOC₂H₅ rlhar2; (CH₃COOC₂H₅ · H)⁺ + (CH₂COOC₂H₅)^-.
