Abstract: PURPOSE: Provided is a method for preparing ultra-fine ammonium perchlorate crystals by salting-out process at high productivity, with no need of separate additives such as a growth protecting agent. CONSTITUTION: The method for preparing ultra-fine ammonium perchlorate crystals comprises the steps of: forming saturated ammonium perchlorate solution by using N-methylpyrrolidone as a solvent for dissolving ammonium perchlorate; adding a halogenated hydrocarbon solvent or an aromatic compound solvent having low solubility to ammonium perchlorate to the saturated ammonium perchlorate solution as a precipitating agent; and mixing them together to obtain ultra-fine ammonium perchlorate crystals having an average crystal size of 2 micrometers or less.

Abstract: PURPOSE: Provided is a purification method of high purity HNIW(hexanitrohexaazaisowurtzitane) used as an oxidant of solid propellants for various rockets, by re-crystallization, thereby eliminating impurities and moisture effectively to allow easy the phase transfer of HNIW and to control the particle sizes easily. CONSTITUTION: The purification method of HNIW characteristically comprises the step of recrystallization by using di(C1-3 alkyl) carbonate, preferably dimethyl carbonate, as a recrystallization solvent. Therefore, HNIW compounds having a purity of 99% are obtained.

Abstract translation: 目的：提供一种高纯度HNIW（六硝基六氮杂异纤锌矿型结构烷烃）的纯化方法，其通过重结晶作为各种火箭的固体推进剂的氧化剂，从而有效地消除杂质和水分，使HNIW易于相转移并控制粒径 容易。 组成：HNIW的纯化方法的特征在于包括使用碳酸二（C 1-3烷基）酯，优选碳酸二甲酯作为重结晶溶剂进行重结晶的步骤。 因此，获得纯度为99％的HNIW化合物。
