General description

2-Methoxyethanol is widely used solvent in various electrochemical studies and industrial units. It exhibits “quasi-aprotic properties. Its solvent characteristics are a mixture of the protic and aprotic solvents. Dissolution of alkali metal salts in 2-methoxyethanol have been studied and their conductance, viscosity and laser-Raman spectra have been evaluated.
