When high and short-pulse voltage was applied with a high repetition frequency to tungsten electrodes placed in water containing ammonia and water containing 2-methyl-2-propanol, gas evolved vigorously from the plasma generated between the electrodes. The main gas evolved was H2 in both aqueous solutions. Decomposition of ammonia provided N2 in addition to H2. In the decomposition of aqueous 2-methyl-2-propanol solution, CO, CO2, methane, ethane, ethylene, and acetylene were generated in addition to H2. The "temperature" deduced by kinetic consideration using the yields of C2 products (ethane, ethylene, and acetylene) formed by the recombination of two methyl radicals was calculated to be ca. 4200 K.
