    摘要: A process for manufacturing a gas generating material includes preparing a hot solution of a metal azide, preferably sodium azide, with metal oxide particles, preferably iron oxide particles, suspended in the solution. The metal azide is precipitated from the solution. The step of precipitating the metal azide from the solution includes cooling the hot solution to decrease the solubility of the metal azide in the solute. The metal azide precipitate and the iron oxide particles are then separated from the liquid.

    摘要: A method of manufacturing a heavy metal azide or a heavy metal trinitro resorcinate by a continuous process in which solutions of the constituents are reacted in an agitated reaction vessel and are then passed through a series of chambers also provided with agitation. Preferably the reaction vessel surface has a low roughness, a high hardness, and the rate of manufacture of the azide or styphnate is controlled.

    摘要: THE PRODUCTION OF HYDRAZOIC ACID BY ACIDIFYING AN ALKALI METAL AZIDE OR ALKALINES EARTH METAL AZIDE IS DESCRIBED. THE BY-PRODUCT SALT OF THE ACID CONCURRENTLY PRODUCED IS SEPARATED FROM THE LIQUID, AND THE SEPARATED LIQUID IS BROUGHT INTO CONTACT WITH FURTHER QUANTITIES OF THE ALKALI METAL AZIDE OR ALKALINE EARTH METAL AZIDE. AZIDE AND ACID VALUES WHICH WOULD OTHERWISE BY LOST IN THE BYPRODUCT STREAM ARE RETAINED.
