摘要：

The effect of H+ ions, liberated in the course of pyrrole electropolymerization, on the chemical decomposition of propylene carbonate (PC) containing LiClO4 as an electrolyte was investigated. GC analyses of model solutions (0.05 0.5 M HClO4/PC) revealed CO2 and allyl alcohol as primary products. Allyl alcohol is converted, probably by reaction with residual water, to 1,2-propanediol. The concentration of both allyl alcohol and 1,2-propanediol increases with time up to about 0.1 M. An excess of pyrrole inhibits the PC decomposition whereas the presence of polypyrrole does not.
