Description
Изобретение относитс к производству .глинозема, который вл етс основным источником получени металлического алюмини .The invention relates to the production of alumina, which is the main source for the production of metallic aluminum.
Известен способ разложени алюминатных растворов с добавкой фосфорной кислоты. Степень разложени раствора при этом 34,7-43,1%.A known method for the decomposition of aluminate solutions with the addition of phosphoric acid. The degree of decomposition of the solution is 34.7-43.1%.
Дл повышени степени разложени алн минатного раствора (л/на 20%) предла-iгаетс фосфорную кислоту перец введе- нием в раствор смешивать с гидроокисью алюмини .To increase the degree of decomposition of the aln minate solution (l / by 20%), phosphoric acid is proposed to be added; pepper is added to the solution and mixed with aluminum hydroxide.
Пример 1. Объем раствора в каждом опыте соответствует 3800О42ООО л. Температурный режим охлаж дени : начальна температура 65 С, конечна температура 45 С, продолжительность разложени 6О ч.Example 1. The volume of the solution in each experiment corresponds to 3800 L OOO. Cooling temperature: initial temperature 65 ° C, final temperature 45 ° C, decomposition time 6 oh.
Берут активную затравку в виде кисло родных дигетерогенных гидратных соединений фосфора с алюминием, приготовленную при взаимодействии фосфорной кислоты с гидроокисью алюмини .They take an active seed in the form of oxygen, diheterogenous hydrated compounds of phosphorus with aluminum, prepared by the interaction of phosphoric acid with aluminum hydroxide.
Дозировка кислоты - 5% от содержани , в растворе. , В это количество кислоты добавл ют 350 кг гидроокиси алюмини из расчета молекул рного отношени Pj Oy:AS.,,73. После перемешивани в течение 30-5О мин между кислотой и гидроокисью алюмини происходит химическое взаимодействие.Acid dosage - 5% of the content, in solution. , To this amount of acid, 350 kg of aluminum hydroxide are added from the calculation of the molecular ratio Pj Oy: AS., 73. After stirring for 30-5 minutes between the acid and aluminum hydroxide, chemical interaction occurs.
Попученную в форме полимерных соединений затравку подают на разложение алюминатного раствора следующего состава: 115,О г/л; , 134,1 г/л; 116,9 г/л; ot 1,92; сСц 1,67; % соды 12.8.Populated in the form of polymeric compounds, the seed is fed to the decomposition of the aluminate solution of the following composition: 115, O g / l; 134.1 g / l; 116.9 g / l; ot 1.92; sSt 1.67; % of soda 12.8.
За 48 и 60 ч глубина разложени соответственно 54,3 и 54,8%.In 48 and 60 hours, the depth of decomposition was 54.3 and 54.8%, respectively.
П р и м е р 2. Опыт провод т аналогично предыдущему, но дл разпож,ени использ5пют алюмннатные растворы ветви спекани следующего состава: PRI mme R 2. The experiment is carried out similarly to the previous one, but aluminum solutions of the sintering branch of the following composition are used for mixing:
87.7г/л; Ма2Оц 93,8 г-/л; N ajjO87.7g / l; Ma2Ots 93.8 g- / l; N ajjO
За 48 и 6О ч глубина разложени соответственно 61,4% и 64,8%.In 48 and 6O hours, the decomposition depth is 61.4% and 64.8%, respectively.
Пример 3, Дл сравнени провод т опыты, с отдельной добавкой фосфорной кислоты и гидроокис алюмини ,Example 3 For comparison, experiments were carried out with a separate addition of phosphoric acid and aluminum hydroxide,
При введении в б йеровский раствор следующего состава: 119,1 г7л; NAgO 142,6 г/л; 123,2 г/л| С31м1 96; о1ц1,69{ % соды 13,65 гидроокиси алюмини из расчета затравочного отношени 0,1 (816 кг затравки на опыт) глубина разложени зч 48 и 6О ч соответственно 27,5 и ЗО,5%.With the introduction of the Bierovsky solution of the following composition: 119.1 g 7l; NAgO 142.6 g / l; 123.2 g / l | S31m1 96; o1ts1,69 {% soda 13.65 aluminum hydroxide based on a seed ratio of 0.1 (816 kg of seed per experiment) decomposition depth of 48 and 6O h, respectively, 27.5 and 30%, 5%.
