Title: Elimination kinetics of β-hydroxynitriles in the gas phase
Journal: J. Org. Chem.
Volume: 12
Page(s): 19 - 23
Year: 1999
Reference type: Journal article
Squib: 1999CHU/DOM19-23
Reaction:
HOCH2CH2CN → CH2O + CH3CN
Reaction order:
1
Temperature:
684 - 713
K
Pressure: 6.27E-2 - 0.22 bar
Rate expression:
2.34x1014 [±2.03x1014 s-1] e-237700 [±7700 J/mole]/RT
Category: Experiment
Data type:
Absolute value measured directly
Pressure dependence:
None reported
Experimental procedure:
Static or low flow - Data taken vs time
Excitation technique:
Thermal
Time resolution:
By end product analysis
Analytical technique:
Pressure measurement
Comments:
Overall kinetics were determined by following pressure vs. time with the individual channels determined by GC product analysis. A free radical inhibitor (toluene) was added in varying amounts. No induction period was observed and varying the surface/volume ratio had no effect on the kinetics in seasoned reactors.
Uncertainties are precision only and are at the 90% confidence level.
