    • A method of forming monoammonium salt of 5,5′-bis-1H-tetrazole (BTA-1NH3) is presented comprising the steps of charging a mixing vessel with a solution of free BTA acid and distilled water, adding ammonium hydroxide in excess to obtain a pH of at least 9.5 and mixing the solution, and adding sulfuric acid cooled to 10-20 degrees Celsius to obtain a pH of at least 4.5 and mixing the solution. A gas generator 10 containing a gas generant 12 containing the BTA-1NH3 formed in accordance with the present invention is also presented. Gas generating systems 180 such as vehicle occupant protection systems 180, containing the gas generator 10, are also provided.
    • 提出了一种形成5,5'-双-1H-四唑(BTA-1NH3)的单铵盐的方法,包括以下步骤:向游离BTA酸和蒸馏水的溶液中加入混合容器,过量加入氢氧化铵得到 pH至少为9.5并混合溶液,并加入冷却至10-20摄氏度的硫酸以获得至少4.5的pH并混合该溶液。 还提供了含有根据本发明形成的含有BTA-1NH 3的气体发生剂12的气体发生器10。 还提供了包含气体发生器10的诸如车辆乘员保护系统180的气体发生系统180。
