heal.abstract	The electrochemical behavior of AlCl3 in propylene carbonate at 25 degrees C was studied by triangular sweep voltammetry with platinum electrodes. The overall mechanism is in agreement with the well-known ErCi reaction scheme: [GRAPHICS] with O: AI(III), where the electrochemical step reflects a quasi-reversible behavior and the following chemical reaction shows a first-order rate, The apparent electron transfer coefficient alpha n(alpha) (where alpha is the transfer coefficient, and n(alpha) is the number of electrons exchanged in the rate determining step) is evaluated at 0.24+/-0.055 by semi-integration of the voltammetric E = f(I) curves. The first-order rate constant of the chemical step was calculated and found to be k(f) congruent to 5/sec. The absence of aluminum deposited on the cathode was confirmed by scanning electron microscopy on electrodes that were polarized at E = -0.65 V/RE for as many as eight hr.	en
