专利汇可以提供Metallic phosphide composition for use in aquatic flares专利检索,专利查询,专利分析的服务。并且Phosphide compositions comprising the phosphides of aluminum and sodium. The compositions may be intermixtures of aluminum phosphide and trisodium phosphide. They may also be the chemical reaction product obtained by reacting aluminum, sodium and phosphorus. When contacted with sea water, the phosphide compositions produce a copious supply of spontaneously inflammable phosphine which is useful as a phosphine generator in aquatic flares and light buoys. Optimally the compositions contain aluminium, sodium and phosphorus in amounts of from 1:1 to 2:1 moles of AlP to Na3P.,下面是Metallic phosphide composition for use in aquatic flares专利的具体信息内容。

1. A PHOSPHIDE COMPOSITION WHICH UPON CONTACT WITH SEA WATER RELEASES PHOSPHINE GAS IN HIGH YIELD, SAIDPHOSPHINE GAZ BEING READILY SELF-INFLAMMABLE WHEN CONTACTED WITH AIR, SAID PHOSPHIDE COMPOSITION COMPRISING THE REACTION PRODUCT PREPARED BY REACTING ALUMINIUM AND SODIUM WITH PHOSPHOROUS IN THE ABSENCE OF OXYGEN, AND RECOVERING THE SAID REACTION PRODUCT.
2. The phosphide composition of claim 1 containing aluminium, sodium and phosphorus in amounts such that all of the aluminium is calculated as AlP, all of the sodium as Na3P, and all of the phosphorus as said AlP and Na3P, and the molar ratio of said AlP to said Na3P is from 1:1 to 2:1.
