Description
Известны способы получени цианамида кальци взаимодействием карбида кальци с азотом с применением в качестве катализаторов Сар2 и СаСЬ. Хлорид кальци примен етс ограниченно ввиду его большой гигроскопичности.Methods are known for producing calcium cyanamide by the interaction of calcium carbide with nitrogen using Sar2 and CaCl2 as catalysts. Calcium chloride is used limitedly due to its high hygroscopicity.
Предлагаетс способ получени цианамида кальци азотированием зернистого карбида кальци при температуре 1150° в црисутствии в качестве катализатора кремнефтористого кальци - CaSiFa.A method is proposed for producing calcium cyanamide by nitriding granular calcium carbide at a temperature of 1150 ° C in the presence of calcium fluorofluoride-CaSiFa as a catalyst.
Процесс азотировани карбида кальци проводитс во вращающейс лабораторной печи при температуре 1150°, в которую загружают 50 г карбида кальци с размерами частиц от 0,2 до 2 мм и от 2 до 5% (от веса карбида кальци ) катализатора.The process of nitriding of calcium carbide is carried out in a rotating laboratory furnace at a temperature of 1150 °, into which 50 g of calcium carbide with particle sizes from 0.2 to 2 mm and from 2 to 5% (by weight of calcium carbide) catalyst are loaded.
В аналогичных услови х проводились опыты по азотированию карбида кальци с применением таких же относительных количеств катализаторов - СаРз и CaCl2.Under similar conditions, experiments were carried out on the nitriding of calcium carbide using the same relative amounts of catalysts — CaP3 and CaCl2.
Проведенными опытами установлено, что при применении в качестве катализатора CaSiFe средний % св занного азота в целевом продукте составл ет 20,75, при применении СаСЬ- 19,26, а при применении CaF2 - 19,59.Experiments have shown that when CaSiFe is used as a catalyst, the average% of bound nitrogen in the target product is 20.75, when CaCl2 is 19.26, and when CaF2 is used it is 19.59.
Таким образом, применение предложенного катализатора по сравнению с известными увеличивает содержание св занного азота в целевом продукте.Thus, the use of the proposed catalyst in comparison with the known increases the content of bound nitrogen in the target product.
Предмет изобретени Subject invention
Способ получени цианамида кальци с применением катализатора , отличающийс тем, что, с целью повышени содержани св занного азота в целевом продукте, в качестве катализатора примен ют кремнефтористый кальций.A method of producing calcium cyanamide using a catalyst, characterized in that calcium fluorofluoride is used as a catalyst to increase the content of bound nitrogen in the target product.
