Description

HovTytiaioT продукт буровато-черного цвета. Содержание ,2%, общее содержание Fe-64,9%, 504 -следы. Удельна  поверхность 42,3 .HovTytiaioT is a brownish-black product. Content, 2%, total Fe-64.9%, 504 traces. The specific surface is 42.3.

Пример 2. Загрузку исходных реагентов и все операции осуществл ют аналогично примеру 1, сушку и дегидратацию провод т при 20°С и остаточном давлении 10-0,.5 мм рт. ст. Полученный продукт имеет следующий состав: ,4%, общее содержание Ре - 59,3% SO 4 -0,53%. Удельна  поверхность 68,4 м2/г.Example 2. The loading of the initial reagents and all operations were carried out analogously to example 1, drying and dehydration was carried out at 20 ° C and a residual pressure of 10-0, .5 mm Hg. Art. The resulting product has the following composition:, 4%, total Fe content - 59.3% SO 4 -0.53%. The specific surface is 68.4 m2 / g.

Пример 3. 350 г FeSO4-71 20 раствор ют в 1,5 л воды, 160 г КОН раствор ют в 1 л воды. Раствор щелочи ввод т при интенсивном перемещивании в раствор соли железа. Осадок гидрата закиси железа промывают 10 раз охлажденной кип ченой водой, фильтруют и сушат при 50°С и остаточном давлении 20- 1 мм рт. ст. Готовый продукт имеет состав: Fe2+-3,7%, Реобщ 65,0%, -следы.Example 3. 350 g of FeSO4-71 20 are dissolved in 1.5 l of water, 160 g of KOH are dissolved in 1 l of water. The alkali solution is introduced with intensive transfer into the salt solution of iron.
