Adsorption of 3-phenyl-1-propanol on gold electrode from perchloric acid solutions

Adsorption of 3-phenyl-1-propanol on gold electrode from perchloric acid solutions. Katoh, K.; Koseki, M. (Fac. Eng., Niigata Univ., Niigata 950-21, Japan). J. Electrochem. Soc., 131(2), 303-5 (English) 1984. CODEN: JESOAN. ISSN: 0013-4651. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 66, 69 Adsorption parameters of 3-phenyl-1-propanol [122-97-4] and some other w-Ph alkanols were calcd. from the isotherm of q/(1 - q)n = Kads.Xorg (Kads = adsorption equil. const. and Xorg = mol fraction of org. specie in soln.). The adsorption peaks appeared at 0.70 and 0.35 V (vs. SCE) for the adsorbate.Several substances with their cas registry numbers 60-12-8 and 7440-57-5 may be metioned in this study. The peak near 0.70 V seems to be due to p-electron interaction of the benzene ring and another peak at 0.35 V to the alc. group as side chain. The peak height of coverage-potential curve at 0.35 V became larger depending upon the no. of C atoms in the aliph. alc. group on the benzene ring. The differential capacitance was measured by a rapid rectangular single-pulse technique, and the voltage-time curve was memorized elec. set by a wave memory. Then, the reproducibility of the capacitance measurement became within ±6%. The values of n and the std. free energy of adsorption of the adsorbate at 0.70 V were calcd. as 2.8 and -7.4 kcal/mol, resp. .
