Temperature dependence of the reactions of Cl with toluene and the xylenes was written by Frazee, W. James;Roscoe, John M.. And the article was included in International Journal of Chemical Kinetics in 2019.Formula: C8H9Cl This article mentions the following:
The temperature dependence of the rate coefficients for the reactions of Cl with toluene and the xylenes was examined from 290 to 362 K. Chem. anal. was by gas chromatog. The relative rate method was used for the kinetic anal., and the relative rate coefficients were converted to absolute values using absolute rate coefficients for the reference reactions obtained from recent critical evaluations. Most of the measurements were made at a total pressure of approx. 100 kPa in argon. There was very little temperature dependence, and variation of the total pressure and the concentration of O2 had no effect. The values of the absolute rate coefficients were independent of the reference reaction used. The reaction of Cl with toluene was studied relative to the reactions of Cl with isobutane, ethane, propane, and n-butane. The results were virtually independent of temperature, giving a mean value of (5 ± 1) x 10-11 cm3 mol.-1 s-1 for the absolute rate coefficient at 95% confidence. The reactions of Cl with the xylenes were studied relative to the reactions of Cl with isobutane, ethane, and propane. The rate coefficients were independent of the xylene isomer and had a very small neg. dependence on temperature The mean value of the absolute rate coefficient at 298 K was (1.4 ± 0.3) x 10-10 cm3 mol.-1 s-1 at the 95% confidence level. The results are in satisfactory agreement with those in the literature, all of which were measured at fixed temperatures very close to 298 K. The kinetic results are discussed in relation to published descriptions of the dynamics of reactions of Cl and OH with organic compounds In the experiment, the researchers used many compounds, for example, 1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9Formula: C8H9Cl).
1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Formula: C8H9Cl
