Temperature Dependences

Mixtures of ethylene oxide or cyclopropane with oxygen and argon were ignited with reflected shock waves In a shock tube. The temperature dependences of the ignition delay and the growth of light emitted during the induction period to explosion of C2H4O-O2 mixtures indicate that the rate-controlling reaction is that of formaldehyde oxidation. The temperature dependence of induction periods for C3H6-O2 mixtures suggests that a complicated but undetermined mechanism controls the delay to ignition.

The Cr* (a7S–y7P) chemiluminescence at 360 nm during the induction period of the C2H2–O2 reaction was studied behind reflected shock waves. When the reaction gas mixture containing 10 p.p.m. Cr(CO)6, 0.5% C2H2, 1.0% O2, and 98.5% Ar was shock heated to 1650 °K, the emission intensity of Cr* grew exponentially with a growth constant equal to the chain branching constant. This observation indicates that reaction(s) leading to Cr* chemiluminescence involve only one chain carrier during the induction period of the C2H2–O2 reaction. The mechanism of the chemical excitation of Cr is discussed.
