Abstract

FIELD: production of crystalline materials having improved physical and chemical characteristics. SUBSTANCE: proposed method involves insertion of small amounts of inorganic material into melt of ammonium nitrate. Substantial amount of said additives is directly inserted into crystalline lattice of NHNO. Mentioned above impurities are inserted during fast crystallization of melt comprising 0.1-1.0 % of additive. Hygroscopic point of thus treated ammonium nitrate is increased by 2.5-3.5 % of its relative moisture content. EFFECT: improved hygroscopicity of desired ammonium nitrate.

Изобретение относится к области получения кристаллических веществ с улучшенными физико-химическими характеристиками. Предлагается способ получения аммиачной селитры, позволяющий улучшить ее гигроскопичность за счет введения в плав селитры небольших количеств добавок неорганических веществ, значительная часть которых внедряется непосредственно в кристаллическую решетку NH4NO3. Примеси вводятся в нее в ходе быстрой кристаллизации плава, содержащего 0,1 - 1,0% добавки. Таким способом можно как минимум повысить гигроскопическую точку селитры на 2,5 - 3,5% относительной влажности. Эффективность действия примесей с повышением температуры возрастает, что важно, поскольку с повышением температуры возрастает и гигроскопичность NH4NO3.The invention relates to the field of obtaining crystalline substances with improved physico-chemical characteristics. A method for producing ammonium nitrate is proposed, which makes it possible to improve its hygroscopicity by introducing small amounts of inorganic substances into the saltpeter melt, a significant part of which is introduced directly into the NH 4 NO 3 crystal lattice. Impurities are introduced into it during the fast crystallization of the melt containing 0.1 - 1.0% of the additive. In this way, you can at least increase the hygroscopic point of nitrate by 2.5 - 3.5% relative humidity. The effectiveness of the action of impurities increases with increasing temperature, which is important, since the hygroscopicity of NH 4 NO 3 also increases with increasing temperature.
