Abstract: The present invention concerns a nitrocellulose-based propellant composition comprising:(a) a nitrate ester based propellant consisting of nitrocellulose alone (single base) or in combination at least with a blasting oil (double or higher base); and(b) a stabilizer consisting of a general formula (I): Wherein the stabilizer combines efficient, long term stability of the nitrocellulose-based propellants composition without formation of any detectable amounts of carcinogenic or mutagenic by-products, such as -NNO groups.
Abstract translation: 本发明涉及一种基于硝化纤维素的推进剂组合物，其包含：（a）由硝基纤维素单独（单一碱）或至少与爆破油（双重或更高碱）组合的基于硝酸酯酯的推进剂; 和（b）由通式（I）组成的稳定剂：其中稳定剂结合硝酸纤维素基推进剂组合物的有效长期稳定性，而不形成任何可检测量的致癌或致突变副产物，例如-NNO基团 。
