Description
Известен способ получени фосфата мочевины взаимодействием мочевины и реактивной фосфорной кислоты с добавлением соды при строгом соблюдении количественных соотношений .A known method for producing urea phosphate by the interaction of urea and reactive phosphoric acid with the addition of soda in strict observance of quantitative ratios.
С целью получени продукта, пригодного в качестве кормовой и консервирующей добавки и увеличени выхода конечного продукта предложен способ получени фосфата мочевины из промышле1игой ортофосфорнои кислоты.In order to obtain a product suitable as a feed and preservative additive and to increase the yield of the final product, a method for the preparation of urea phosphate from industrial phosphoric acid has been proposed.
Пример 1. 60 кг размельченной кормоиой мочевины загружают в фарфоровый чан, и с перемешиванием при обычной температуре добавл ют 150 кг продажной 73%-пой ортофосфорнои кислоты (ортофосфорна кислога Лижневолжского совнархоза,- термическа , сорт г торой, ОСТ 10I14-39). Персменшпацис njioiio.uiT до нолпого растворени мочевины в ортофосфор1гпй кислоте (50-60 мпн). 3;iTei t реакгиюнную смесь выдерживают при обычной температуре 12 час. В течен 1е этого времени смесь превращаетс в сплошную твердую массу (юсфата мочевни 1Г, которую перенос т на нутч-фн.п.тр с бумажной прокладкой и при интенсив1 ом вакуумн)о.чанни в течение 2 час освобождают от маточника.Example 1. 60 kg of crushed urea feed is loaded into a porcelain vat, and 150 kg of sales 73% orthophosphoric acid (orthophosphoric acid of the Lizhnevolzhsky Sovnarkhoz, heat, grade, OST 10I14-39) is added with stirring at ordinary temperature. Until the solution of urea in orthophosphoric acid (50-60 mpn). 3; iTei t, the reaction mixture is kept at ambient temperature for 12 hours. During this time, the mixture turns into a solid solid mass (1G urea yuspata, which is transferred onto a suction-fn.ptr with a paper pad and under intensive vacuum) of the oodule over the course of 2 hours from the mother liquor.
После удалени маточного раствора кристаллы фосфата мочевины промывают небо.гьншм количеством воды (5-б л). Затем продукт выгружают из путч-фильтра, распредел ют егоAfter removal of the mother liquor, the urea phosphate crystals are washed with a sky of water (5 L). The product is then discharged from the coup filter, distributed
слоем 4-5 см на противн х и сушат при 50- 70°С в течение 12-15 час. Выход фосфага мочевины 136 кг (87,2%, счита па вз тую мочевину ). Пример 2. При повторном пригогоплеНИИ фосфата мочевины в тех же услови х и при тех же режимах, что и в примере 1, из 100 кг кормовой мочевипы и 240 кг 73%-ной ортофосфориой кислоты получают 226 i:s фосфата мочевины (выход 86,8%, счита tia вз тую мочевину).a layer of 4-5 cm on opposite and dried at 50-70 ° C for 12-15 hours. The yield of urea phosphate is 136 kg (87.2%, considering the taken urea). Example 2. When urea phosphate is repeated, under the same conditions and under the same conditions as in example 1, 226 i: s of urea phosphate is obtained from 100 kg of feed urea and 240 kg of 73% orthophosphoric acid (yield 86, 8% (tia taken urea).
Предмет изобретени Subject invention
Способ получени фосфата мочевины и;) мочевин1 г и ортофосфорнои кислоты, отличающийс тем, что, с нелью получеии продукта, пригодного дл применении в качестве кормовон и консервирую цей добавки, и увеличени выхода продукта примен ют промышленную орт()фосфорг1ую кислоту.The method of producing urea phosphate and;) urea g and orthophosphoric acid, characterized in that, in order to obtain a product suitable for use as feed and preservative additives, and to increase the yield of the product, industrial grade () phosphoric acid is used.
