Cyclization Kinetics of Aliphatic í-/3-Chloroethylamin es 281 tion to light results in a magnetic change which could be interpreted as being due to appreciable dissociation.A considerable degree of free radical formation is observed with 2,2'-dibenzothiazyl disulfide. The concentration of the thiol radicals in toluene has been measured up to 150°.

Low-conversion and integral-conversion experiments were performed to investigate the rate of the catalytic oxidation of sulfur dioxide using two commercial vanadium pentoxide catalysts at temperatures from 450-580°C over a wide range of compositions. Temperature-dependent correlations were derived for each catalyst based on a new form of kinetic expression. These correlations fitted the data almost as accurately as the particular correlations derived for each temperature. A temperature-dependent relationship was also derived using the proposed kinetic expression for the poisoned catalyst data published by Ishii (I960).
