Abstract

The adsorption of benzene on a fresh steel surface was carried out in high vacuum at room temperature. The fresh surface was formed by cutting in a high vacuum chamber, and benzene was allowed to adsorb on the surface during cutting. The adsorption and the surface reaction of benzene was monitored with a quadrupole mass spectrometer. It was found that the cut surface was so active that the catalytic decomposition of benzene occured even at room temperature. The adsorption rate and the sticking probability of benzene were estimated. The adsorption rate linearly increased with cutting speed, that is, the formation rate of the fresh steel surface. It was found that the adsorbed amount was under the monolayer level, and that the adsorption activity of toluene on the fresh surface was about two times larger than that of benzene.
