Potassium Benzoate for Pyrotechnic Whistling Compositions: Its Synthesis and Characterization as an Anhydrous Salt,

Abstract

Potassium benzoate is one of the ingredients in the formulation SR 136 Whistling Composition. However, some ambiguity exists in the chemical literature as to its hydration state. In this investigation, it was established that potassium benzoate crystallizes from water as colourless plates containing no water of crystallization and it does not appear to take up water from its environment. Its DSC thermogram, over the temperature range 310 K - 750 K, consists of a single, sharp and symmetrical endotherm, occurring near 714 K and probably due to melting, the heat of this reaction being ca 213 J/gram (50.9 cal/gram). It can be prepared from stoichiometric amounts of benzoic acid and either potassium hydroxide or potassium bicarbonate.
