Shock-Induced Reaction in Carbon Disulfide.
Abstract
In the studies of the shock-induced chemical decomposition of liquid CS2, it has been shown that the liquid under compression transforms to a higher density form and that this transformation occurs under static pressure at 45 kbar and 175 C. Previous shock experiments have shown that a similar transformation occurs in a single shock at approximately 60 kbar and 1000 C. Sheffield at WSU has shown that the transformation occurs in a reflected shock at pressures greater than 75 kbar and at temperatures greater than 750 C. The transformation or reaction time was found to decrease from about 400 nsec at 79 kbar to less than 10 nsec at 130 kbar. At lower pressures there is an induction time decreasing from 300 nsec at 79 kbar to less than 6 nsec at 106 kbar. We have finished and reported the work on shock-induced light emission in CS2 experiments and gone on to redesign the absorption experiment to overcome two problems. One was the inadequacy of the light source being used. The present source has an effective temperature of about 15000 K. With this the spectrograph-streak camera produces a satisfactory image with time and spectral resolutions of about 30 nsec and 30 A, respectively. The other difficulty lay with the effects of shock on the light reflection. This has been resolved by placing the reflector in the projectile, where it is shock-free during the significant part of the experiment.
