Synthesis and utilization of potassium phosphide as a day/night marine signal

Synthesis and utilization of potassium phosphide as a day/night marine signal. Hart, Mary R.; Kennedy, John R.; Farren, Ronald E. (Appl. Sci. Dep., Nav. Weapons Support Cent. There are some commonly used reagents like 20770-41-6 in this article., Crane, IN 47522, USA). Proc. Int. Pyrotech. Semin., 9th, 917-38 (English) 1984. CODEN: PPYSD7. ISSN: 0270-1898. DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) Section cross-reference(s): 49 Several techniques were investigated to det. the optimum method for scale-up of K3P synthesis, with consideration being given to 3 areas of major concern: the reactivity of both reactants and products with atm. water and O, the friction sensitivity of red P, and excess heat released by the exothermic synthesis reaction. The expts. were done in a glove box under inert atm. The reactant combinations were adjusted in various solvents; the solvents used were mineral oil, THF [109-99-9]/naphthalene (I) [91-20-3], I-cyclohexane (II) [110-82-7], and II. Testing of several batches of the K3P product by exposure to water showed that K3P had favorable characteristics for both day and night signaling; upon hydrolysis, the compd. produced a flame as well as a plume of whitish-gray smoke. Signal initiation by reaction with water showed that K3P is an excellent signaling device in the rain. .
