Abstract

1,168,092. Urea-containing fire extinguishing compositions. IMPERIAL CHEMICAL INDUSTRIES Ltd. 10 Oct., 1967 [3 Nov., 1966; 7 Feb., 1967], Nos. 49366/66 and 5837/67. Heading A5A. [Also in Division C2] Compositions of matter possessing fireextinguishing properties comprise compounds of the empirical molecular formula MC 2 N 2 H 3 O 3 , where M represents an atom of sodium or potassium, which exhibit characteristic infra-red absorption spectra, may be obtained by heating a mixture of urea and at least one alkali selected from bicarbonates, carbonates, sesquicarbonates and hydroxides of sodium and potassium at temperatures below 150‹C. The compositions may also contain at least one additive selected from anticaking agents, free-flowing agents, surface-active agents, water-repelling agents, and substances that give compatibility with fire-fighting foams; other materials possessing fire-retarding properties, e.g. ammonium and zinc sulphates, the phosphates and borates. of ammonia, alkali metals, zinc aluminium and calcium, in powder form non-inflammable urea/formaldehyde and phenol/formaldehyde condensation products, and non-inflammable halogen-containing compounds may also be present.
