Cyanogen fluoride was prepared and its chemical properties were determined, and its solubility, toxicity and service time were measured. The results indicated that the gas is not particularly suited as a war gas. The service times for arsine, phosgene and phosphorous trifluoride were determined for a number of respirator charcoal samples by means of an apparatus which approximated the behavior of the human lung. All the impregnated charcoal samples submitted were shown to provide fairly adequate protection against the gases studied. An intensive study of the phase equilibria of the two component system ethylene – propylene has been made in the cr1t1cal temperature region. It was shown that when the med1um is stirred no discontinuity in density or phase composition occurs at the critical temperature, while without stirring the attainment of equilibrium is slow and uncertain.
