Title:   Experimental and numerical studies of ethanol decomposition reactions
Journal:   J. Phys. Chem. A
Volume:   108
Page(s):   7671 - 7680
Year:   2004
Reference type:   Journal article
Squib:   2004LI/KAZ7671-7680

Reaction:   C2H5OHC2H4 + H2O
Reaction order:   1
Temperature:   300 - 2500 K
Pressure:  10.13 bar
Rate expression:   2.08x1014 [s-1] (T/298 K)-0.74 e-277055 [J/mole]/RT
Category:  Review
Data type:   Experimental value and limited review
Pressure dependence:   Rate constant is pressure dependent
Comments:   The authors used a variable pressure flow reactor to study ethanol pyrolysis at 1.7-3.0 atm and 1045-1080 K in the presence of radical chain inhibitor. Rate constants were presented graphically but the numerical results from the experiments were NOT reported.

The authors used their data together with that from the literature to perform a master equation multi-channel RRKM analysis and derive the reported rate constants based on their model.
