Article abstract of DOI:10.1246/bcsj.58.2411

Rate constants for reactions with ozone were measured for four kinds of simple ketenes (ketene, methylketene, ethylketene and dimethylketene) in 1 atm of air.The rate constants were obtained as upper limits; < 1x10^-21, 7x10^-18, 1x10^-18, and 4x10^-17 cm³ molecule^-1 s^-1, respectively.The mechanism of the reactions was proposed to be similar to that for the liquid-phase reactions.
