Изобретение относитс к способу получени жидких азотно-калиевых удобрений, примен емых в сельском хоз йстве.The invention relates to a method for producing liquid nitrogen-potassium fertilizers used in agriculture.
Известен способ получени жидких азотнокалиевых удобрений на основе нитрита кали , заключающийс в том, что 10-70%-ный раствор нитрита кали ввод т карбонат кали в количестве 2-50% к общему весу раствора. Температура кристаллизации полученного раствора составл ет минус 38,б°С, общее содержание питательных веществ 36,1 %.A known method of producing liquid nitrogen-potassium fertilizers based on potassium nitrite, which consists in introducing 10-70% solution of potassium nitrite in an amount of 2-50% potassium carbonate to the total weight of the solution. The crystallization temperature of the resulting solution is minus 38, b ° C, the total nutrient content is 36.1%.
Цель изобретени - понижение температуры кристаллизации при одновременном повыщении содержани питательных веществ.The purpose of the invention is to lower the crystallization temperature while increasing the nutrient content.
Дл этого кристаллический нитрит кали ввод т в 5-52%-ный раствор сульфита кали в количестве 2-60% к общему весу раствора. Полученное удобрение содержит серу и повыщенное содержание суммы питательных веществ .For this, crystalline potassium nitrite is introduced into a 5-52% solution of potassium sulfite in an amount of 2-60% to the total weight of the solution. The resulting fertilizer contains sulfur and an increased amount of nutrients.
Пример I. Приготавливают раствор из 98-99% К250з вводе (20% К25Оз+80% ПгО) и- постепенно к нему прибавл ют кристаллический нитрит кали до тех пор, пока температура кристаллизации раствора не начнет човыщатьс .Example I. A solution is prepared from 98-99% K2503 injecting (20% K25Oz + 80% PGO) and -crystalline crystalline potassium nitrite is added to it until the crystallization temperature of the solution begins to increase.
В результате получают раствор, содержащий 13,2% К25Оз, 54% KNOs и 32,8% . Температура кристаллизации такого раствора минус 42°С, соотнощение в нем N : КгО 1:4 и общее содержание питательных веществ составл ет 46,6%.The result is a solution containing 13.2% K25Oz, 54% KNOs and 32.8%. The crystallization temperature of this solution is minus 42 ° C, the N: CrO ratio is 1: 4, and the total nutrient content is 46.6%.
Пример 2. Готов т раствор из 98-99% К25Оз в воде (40% K2SO3 + 60% НгО) и постепенно к нему прибавл ют кристаллический нитрит кали , пока температура кристаллизации раствора не начнет повыщатьс . В результате получают раствор, содержащий 21,6% К250з, 46,0% KN02, 32,4% НгО, с температурой кристаллизации минус 44°С, соотнощением в нем N : К2О 1 : 5,0 и общим содержанием питательных веществ 45,7%.Example 2. A solution of 98-99% K25Oz in water (40% K2SO3 + 60% HgO) is prepared and crystalline potassium nitrite is added to it until the crystallization temperature of the solution starts to rise. The result is a solution containing 21.6% K250z, 46.0% KN02, 32.4% HgO, with a crystallization temperature of minus 44 ° C, a N: K2O ratio of 1: 5.0 and a total nutrient content of 45, 7%.
