Abstract
Benzene decomposes when shocked to pressures greater than 13 GPa. However, few products of the decomposition reactions have been identified in situ or by recovery methods. This paper reports the detection by time-resolved (50-to-120 nsec) chemiluminescence spectroscopy of excited molecular products of the decomposition of benzene at pressures from 24 to 63 GPa. Strong spectral bands characteristic of C2 are readily identified among other features and a gray-body background. The dependence of the spectra on shock parameters are breifly discussed in terms of known decomposition mechanisms of highly excited benzene.
