RATE CONSTANTS FOR THE GAS-PHASE REACTIONS OF ALKANES WITH CL ATOMS AT 296 2 K

摘要: Rate constants for the gas-phase reactions of Cl atom with a series alkanes have been determined at 296 ± 2 K using relative rate method. Using constant reaction n-butane 1.94 × 10−10 cm3 molecule−1 s−1, obtained (in units 10−11 s−1) were: 2-methylpentane, 25.0 0.8; 3-methylpentane, 24.8 0.6; cyclohexane, 30.8 1.2; cyclohexane-d12, 25.6 2,4-dimethylpentane, 2,2,3-trimethylbutane, 17.9 0.7; methylcyclohexane, 34.7 n-octane, 40.5 2,2,4-trimethylpentane, 23.1 2,2,3,3-tetramethylbutane, 15.6 0.9; n-nonane, 42.9 n-decane, 48.7 1.8; and cis-bicyclo[4.4.0]decane, 43.1 0.8, where indicated errors are two least-squares standard deviations do not include uncertainties in constant. These data combined previously ten C2C7 this entire set has used to develop an estimation method allowing room temperature be calculated. © 1995 John Wiley & Sons, Inc.
