Изобретение относитс к способу получени органо-минерального удобрени , содержащего микроэлементы.The invention relates to a method for producing an organic-mineral fertilizer containing trace elements.
Известен способ получени сложного органо-минерального удобрени путем обработки бурого угл или лигнина кислородом при температуре 165-160°С и давлении 38-40 атм. Полученную массу обрабатывают аммиаком и получают обогащенный азотом уголь или лигнин 1. Недостатком этого способа вл етс трудоемкость операции и необходимость применени удобрений в больших количествах.A known method for producing a complex organo-mineral fertilizer by treating brown coal or lignin with oxygen at a temperature of 165-160 ° C and a pressure of 38-40 atm. The resulting mass is treated with ammonia and carbon or lignin 1 enriched with nitrogen is obtained. The disadvantage of this method is the laboriousness of the operation and the need to use fertilizers in large quantities.
Наиболее близким по своей технической сущности вл етс способ получени сложного органо-минерального удобрени путем обработки бурого угл или торфа или аналогичного материала разбавленной азотной кислотой (20-50%) при температуре 60-100°С с последующей нейтрализацией полученного продукта щелочью 2.The closest in technical essence is a method of obtaining complex organo-mineral fertilizer by treating brown coal or peat or similar material with dilute nitric acid (20-50%) at a temperature of 60-100 ° C, followed by neutralization of the resulting product with alkali 2.
Однако по этому способу происходит только нитрование гуминовых соединений без глубокой их деструкции до низкомолекул рных соединений и невозможно получить соединени с сол ми поливалентных металлов, например железа или марганца, тииа внутрикомплексных соединений, хорошо растворимых в воде.However, according to this method, only nitration of humic compounds without deep destruction of them to low molecular weight compounds occurs and it is impossible to obtain compounds with salts of polyvalent metals, for example iron or manganese, tia complex compounds that are readily soluble in water.
Дл обогащени удобрений внутрикомплексными соединени ми с металлами переменной валентности и низкомолекул рными соединени ми высокодеструктированного угл по предлагаемому способу бурый уголь или торф или аналогичный материал обрабатывают концентрированной азотной кислотой с уд. весом 1,2-1,4 при 60-100°С с последующей нейтрализацией полученного продукта щелочью и обработкой продзктов нейтрализации карбонатами железа или марганца при температуре 50-100°С. Обработку азотной кислотой следует вести в течение 1-6 ч.In order to enrich the fertilizers with intracomplex compounds with metals of variable valence and low molecular weight compounds of highly degraded coal according to the proposed method, brown coal or peat or similar material is treated with concentrated nitric acid with beats. weighing 1.2-1.4 at 60-100 ° C, followed by neutralization of the resulting product with alkali and treatment of products neutralized with iron or manganese carbonates at a temperature of 50-100 ° C. Treatment with nitric acid should be carried out within 1-6 hours.
Пример. 1 кг сухого молотого бурого угл окисл ют 2 л азотной кислоты (уд. весExample. 1 kg of dry ground brown coal is oxidized by 2 liters of nitric acid (sp. Weight
1,2-1,4) при 60°С в течение 5 ч. К окисленному продукту добавл ют разбавленный раствор щелочи из расчета: на 1 кг бурового угл 5 л н. раствора едкого натра до максимального извлечени продуктов окислени . К полученной смеси при нагревании до 60°С добавл ют карбонат железа до окончани реакции . Полученный раствор, содержащий удобрение , очищают декантацией. Его можно хранить в течение нескольких лет. Дл получени 1.2-1.4) at 60 ° C for 5 hours. A dilute alkali solution is added to the oxidized product at the rate of: 1 kg of drilling coal 5 liters. caustic soda solution to the maximum extraction of oxidation products. Iron carbonate is added to the mixture while heating to 60 ° C until the end of the reaction. The resulting solution containing the fertilizer is purified by decantation. It can be stored for several years. To obtain
удобрени в сухом виде раствор упаривают при 40-80°С. Получают сухой порошок, который хорошо раствор етс в воде без изменени химических и биологических свойств. Благодар тому, что полученные удобрени dry fertilizer solution is evaporated at 40-80 ° C. A dry powder is obtained, which dissolves well in water without changing chemical and biological properties. Thanks to the fact that the fertilizer obtained
