Electrodeposition of Aluminium from Baths Consisting of Aluminium Bromide and Low Volatile Organic Solvent Electrodeposition of aluminium from fused salt baths. consisting of 3mol./L AlBr_3 and low volatilearomatic solvent such as tetrarine, mesitvlene and 1.2.4-trimethylbenzene, were studied. These baths are homogeneous liquid at ordinary temperatures. Anode efficiency for aluminium dissolution was 100％ at most conditions, and cathode efficiency of 90％ or more was obtained at appropriate conditions. Satisfactory deposits were Obtained from 3mol/L AlBr_3/mesitylene bath, with an addition of 0.1～0.5mol/L acetanilide. at 30～40℃ and at 10～20mA/cm^2.
