Abstract
Изобретение относитс к способам получени арсената железа (Ш) и позвол ет повысить выход продукта. Способ заключаетс в том, что арсенопирит (FEASS) обрабатывают 10-20%-ной азотной кислотой. Образующийс при этом осадок промывают сероуглеродом и этиловым спиртом, а затем бидистилл том и сушат на воздухе до посто нной массы. Выход продукта составл ет ъ96%. 1 табл.The invention relates to methods for producing iron (III) arsenate and allows for an increase in the yield of the product. The method is that arsenopyrite (FEASS) is treated with 10-20% nitric acid. The precipitate thus formed is washed with carbon disulfide and ethyl alcohol, and then bidistillate and dried in air to constant weight. The product yield is about 96%. 1 tab.
Description
Изобретение относитс к способам получени арсената железа (Hi), используемого в ветеринарии как антгельментик рогатого скота, а также дл пропитки древесины и в процессах сорбции и ионного обменаThe invention relates to methods for producing arsenate of iron (Hi), used in veterinary medicine as antgelmentik cattle, as well as for impregnation of wood and in the processes of sorption and ion exchange
Цель изобретени - повышение выхода продуктаThe purpose of the invention is to increase the yield of the product.
Пример К 32 56 г (0 20 моль) арсено пирита, просе нного в 0 25-миллиметровом сите добавл ют 100 г 10%-ной азотной кис лоты (25% от теоретического) Суспензию постепенно нагревают при посто нном перемешивании С 60-65°С начинаетс бур- мз реакци с интенсивным выделением оксида азота (II) Процесс протекает по еле дующему уравнениюExample To 32 56 g (0 20 mol) of arseno pyrite, sifted in 0 25 mm sieve, 100 g of 10% nitric acid (25% of the theoretical) are added. The suspension is gradually heated with constant stirring With 60-65 ° C begins the reaction with intensive release of nitric oxide (II). The process proceeds according to the following equation
3FeAsS + 8HN03 - ЗРеАзОл J ЗЬ f 8NO + 4Н203FeAsS + 8HN03 - ZRAZOl J Zb f 8NO + 4H20
После того, как заканчиваетс бурна стади реакции (на что уходит 10 15 мин), к реакционной массе постепенно при посто нном перемешивании добавл ю1 303,2 г оставшегос раствора азотной кис/юты В конце процесса с целью полного окислени мышь ка содержимое колбы кип т т 25-30 мин жидкую фазу декантируют осадок обрабатывают 30 мл сероуглерода (2 раза по 15 мл) и 40 мл этилового спирта Затем целевой продукт тщательно промывают биди- стилп том и сушат на воздухе до посто нной массы При этом получают44,72 г (0 194 моль) зрсената железа в виде белого вещества что составл ет 96 9% от теоретического Найдено % As 32 27 Н201533After the boil reaction stage ends (which takes 10–15 minutes), 303.2 g of the remaining nitric acid solution / urya is gradually added to the reaction mass with constant stirring. At the end of the process, the contents of the flask are completely boiled. The precipitate is decanted for 25-30 min. The precipitate is treated with 30 ml of carbon disulphide (2 times 15 ml) and 40 ml of ethyl alcohol. Then, the target product is thoroughly washed with a bidistilplate and dried in air to constant weight. This gives 44.72 g (0 194 mol) of iron zrsenate as white matter h is about 96% of the theoretical 9 Found% As 32 27 N201533
