Title: Gas-Phase Hydrolysis of SOCl2 at 297 and 309 K: Implications for Its Atmospheric Fate
Journal: J. Phys. Chem. A
Volume: 107
Page(s): 6183 - 6190
Year: 2003
Reference type: Journal article
Squib: 2003JOH/DIS6183-6190
Reaction:
SOCl2 + H2O → SO2 + HCl + HCl
Reaction order:
2
Temperature:
297
K
Pressure: 0.99 - 1.00 bar
Rate expression:
6.3x10-21 [±3.5x10-21 cm3/molecule s]
Category: Experiment
Data type:
Absolute value measured directly
Pressure dependence:
Rate constant is pressure independent
Experimental procedure:
Static or low flow - Data taken vs time
Excitation technique:
Thermal
Time resolution:
In real time
Analytical technique:
Fourier transform (FTIR)
Comments:
Experiments carried out with a pulsed-aliquot kinetic method. Concentrations also measured by GC-MS.
SOCl2 decay data are consistent wtih, but do not prove, a bimolecular gas-phase hydrolysis reaction.
