CARBON DISULFIDE FLAMES, INFLUENCE OF MOISTURE

Abstract

The burning velocity of carbon disulfide - air flames increases exponentially as the concentration of water is reduced so that on a Bunsen burner for very dry mixtures flash back was inescapable. Flame propagation in a 1.5-inch closed tube increased from 550 for a water-saturated to 1150 cm/sec for a very dry mixture. The minimum spark-ignition energy and quenching distance also were markedly affected by the moisture content. Both a diffusional transfer and a thermal transfer theory are marginal in explaining the results. However, it appears more reasonable that hydrogen atoms or hydrogen-containing species from water inhibit the reaction chain.
