Abstract : The thermodynamic information obtained and the instrumental techniques developed should be of importance in synthesizing new, dense, energetic hydrogen-rich fuels. Calculations were also performed to approximate thermodynamic data for one of these fuels, NH4. Chemical systems studied experimentally under applied pressures up to 40 KB included the phosphorus (phosphine)-hydrogen system and the ammonia-hydrogen system. Experimental techniques for performing in situ-post mortem mass spectrometric analysis of reaction mixtures which have been exposed to high pressures (150,000 psi) were developed during the phosphorus work and used to study ammonia-hydrogen reactions. In the phosphorus (phosphine)-hydrogen studies no indications of PH5 were observed, although H2 was evolved in grest excess. Ten NH3-H2 experiments were performed at pressures around 10,000 psi with the use of heated platinum or palladium wires as catalysts. Indications of new species at M/e = 36 and at M/e - 20 were observed, accompanied by a slight indication at M/e = 18. (Author)
