Abstract: In this paper, the kinectics and quantum yields of heteropolyanion P_2Mo_(18)O_(62)~(6-) excitation state reduced by methanol, ethanol, n-propanol, 2-propanol, ethylene glycol, and tert-butyl alcohol are reported.We have measured the conversion rate of HPC to its reduced form HPB under the irradiation of Xe lamp when mixed with aliphatic alcohol. By a good linear relation between the concentration of HPB and the reaction time (Figure 2), a zero -order reaction was shown. The quantum yield of HPB was measured in the presence of aliphatic alcohol, the rate constants κ_r defined by d(HPB)/dt=κ_r(HPC*) (Aliphatic alcohol) wwere also estimated. The sequence of the κ_r is as follows:ethylene glycol>2-propanol>n-propanol~ethanol>methanol>>tert-butyl alcoholIn addition, the spectra and properties of both HPC and HPB have been compared.
