Abstract The investigation is aimed to study the possibility of creation of new CHNO‐oxidizers for smokeless gas‐generating compositions for airbag inflators. For ensuring low amount of CO and nitrogen oxides in combustion products it is necessary to create stoichiometric compositions with a relatively low combustion temperature. Ways to create new oxidizers acceptable to this requirement are examined, mainly by introducing low‐enthalpy oxygen‐containing groups into the oxidizer molecule. Standard enthalpy of formation (Δ f H °) has been calculated for substances with unknown Δ f H °, thermal stability has been qualitatively estimated, and combustion temperatures of stoichiometric compositions have been calculated.
