  • the gas-generating mixture usually contains sodium azide.
  • Natriu azid in itself is toxic and can easily mix with heavy metals such as.
  • B. Implement copper and lead to form extremely dangerous and violently reacting compounds. Special measures must therefore be taken in the manufacture of the raw material, the gas mixture, its processing and quality control. For this reason, the disposal of the sodium azide, for example when replacing defective gas generators or when scrapping the vehicles, is also a particular problem. Misuse must also be prevented.

If ammonium perchlorate is used, the simultaneous presence of zinc compounds is particularly advantageous since the risk of hydrochloric acid formation can thereby be avoided. An excess of sodium and potassium compounds is harmless since this reacts with the reaction gases to form harmless carbonates.
  • the partial or complete replacement of the alkali nitrate with strontium nitrate leads to a significant reduction in the slag content.
  • the mixing ratio of the nitrogen-containing compounds, for example the tetrazoles and triazoles, to the oxidizing agents is balanced so that an excess of oxygen is formed when the gas mixture is burned off. This excess of oxygen shifts the CO / CO 2 equilibrium towards carbon dioxide.
  • Moderators who intervene in the implementation in the form of heterogeneous catalysis are metals, metal oxides and / or metal carbonates and / or metal sulfides. Boron, silicon, copper, iron, titanium, zinc or molybdenum can preferably be used as metals. Calcium carbonate can also be used. Mixtures of these moderators can also be used.
  • Moderators who intervene in the implementation in the form of homogeneous catalysis are, for example, sulfur, boron, silicon or ferrocene and its derivatives.

  • Example 2 the addition of only 1% by weight of zinc peroxide surprisingly leads to a significant reduction in the CO content to 1100 ppm with otherwise unchanged test parameters.
  • the changes in the composition of the mixtures in Examples 3 to 5 lead to poorer results.
  • composition (% by weight)
  • Measurement results in the 60 1 test can:
  • reaction time is between 40 and 60% of the maximum pressure in milliseconds
  • Examples 6 to 9 show that the addition of the Zn, Ca and Mg salts of 5-aminotetrazole (Me (5-ATZ) 2 ) has a favorable effect on the vapor composition. A clear reduction in the CO content is found. The reaction rate is also influenced. Composition (% by weight)
  • reaction time is between 40 and 60% of the maximum pressure in milliseconds
  • Examples 10 to 13 differ in the proportion of sodium nitrate / strontium nitrate as the oxidizing agent. With an increasing proportion of strontium nitrate, the mass of the slag emerging into the jug is reduced. This means that the filterability of the slag is improved by adding strontium nitrate - after the reaction - in the filter of the generator. At the same time, the CO content of the reaction gas can be influenced favorably.
