“…The ratio of the reaction rates for (1) and (2) should be nearly proportional to the concentration of OCS and S02 observed, since any SO from reaction 2, provided it is not lost to the walls, will be converted to S02 through the reaction SO + 02 -* S02 + O (4) at the flow rates employed. The fate of SO produced by reaction 2 is critical, however, since it can also react with CS to produce OCS CS + SO -OCS 4-S (5) thereby tending to negate the above analysis. However, if reaction 5 was the source of OCS observed in the flow stream, the OCS to S02 ratio would depend on the ratio of the reactants, CS and 02.…”

Publication costs assisted by McDonnell Douglas CorporationA low-pressure flame fueled with CS and O2 is reported. The CS-O2 mixture is hypergolic at room temperature and exhibits the characteristics of a branched chain reaction. Measurements of the velocity and temperature of the flame are reported, and a discussion of the probable chemistry based on the observations of the stable end products of the flame is included. In a separate experiment, the absolute rate of the bimolecular reaction between CS and O2 was measured. The dominant reaction path produces OCS and 0 and has a rate constant of 2.7 ± 1 X 10s cm3/mol sec at 293 K.

“…The CS chemistry becomes critical if the CO chemical laser is fueled with CS, which has many advantages over CS2-fueled systems. 5 For this reason and because of conflicting reports6-8 about the rate of the reaction between CS and O2, we have investigated the reactivity of CS with O2.…”

“…Noteworthy also are other methods for the active-center generation that were used to provide the operating conditions for chemical CO lasers in the mode of supersonic flow of a reactive mixture. Dissociation of carbon disulfide in various facilities was tested both for lasers with subsonic flow of the mixture [21,22] and with supersonic flows [23][24][25].…”

The present state of research concerning a cw chemical CO laser whose operation is based on a chain chemical reaction of carbon disulfide oxidation is describe. The role of various chemical-kinetics processes in CS2 oxidation in the gas phase is discussed mud the key processes are identified. Appropriate experimental techniques are described. The results of studies of the ~eld of laser emission from CO molecules containLng CS~, 02, and various additives in the optical resonator are ~ven. The energy-related c~haracteristics of various types of chemical CO lasers using subsonic and supersonic flows of reactive mixure are reported. The influence of a number of parameters on the energetic characteristics of the lasers is discussed.
