The conductance of s-acetylthlochollne halides and perchlorate has been measured In n-propanol at 25 ^oC. The data were analyzed using the Fuoss·Onsager equation for 1 : 1 associated electrolytes and the characteristic function, A_o (conductance at lnfinltedllution), d (contact distance) and K_A (association constant) has been derived. The association constant K,. was analyzed on the basis of the solvent separated-ion pair model.
