Description
(54) СПОСОБ ПОЛУЧЕНИЯ РАСТВОРА СИЛИКАТА НАТРИЯ(54) METHOD FOR GETTING SODIUM SILICATE SOLUTION
Изобретение касаетс получени силикатов натри и может быть использовано в производстве катализаторов двуокиси кремни .The invention relates to the preparation of sodium silicates and can be used in the manufacture of silica catalysts.
Известен способ получени раствор силиката натри путем обработки каолина 10-12%-ным раствором едкого натра при нагревании при мольном соотношении S±O , равном 1 1.A known method of obtaining a solution of sodium silicate by treating the kaolin with 10-12% sodium hydroxide solution with heating at a molar ratio of S ± O equal to 1 1.
Известен также способ получени раствора силиката натри , включающий обработку диатомита раствором едкого натра при 185-90 С в течение 1 ч с . последующей фильтрацией полученной суспензии 2.There is also known a method of obtaining a solution of sodium silicate, which includes the treatment of diatomite with a solution of sodium hydroxide at 185-90 ° C for 1 h s. subsequent filtration of the resulting suspension 2.
Недостатком известных способ.ов вл етс невысока степень чистоты целевого продукта.A disadvantage of the known methods is the low purity of the target product.
Это достигаетс тем, что перед обработкой диатомит подвергают прокалке , а гидроокись натри использую с концентрацией 2-8%, причем прокалку осуществл ют при 550-700 с в течение 5-7 ч, а обработку ведут при мольном отношении диатомита к щелочи равном 1,2-4,1:1,1.This is achieved by the fact that before treatment the diatomite is subjected to calcining, and sodium hydroxide is used with a concentration of 2-8%, and calcining is carried out at 550-700 s for 5-7 hours, and the treatment is carried out at a molar ratio of diatomite to alkali equal to 1, 2-4,1: 1,1.
Способ осуществл ют следуквдим образом .The method is carried out in the following manner.
Диатомит Джрадзорского месторождени Арм нской ССР предварительноDiatomite of the Dzhradzorsky deposit of the Armed NSSR
прокаливают при 550-700 С в течение 5-7 ч. Затем прокаленный диатомит перенос т в термостат и обрабатывают его 2-8%-ным раствором NaOH марки Осч 18-3 и при перемешивании в{лдерживают 2-5 ч при 60-95°С. Затем полученную суспензию фильтруют на воронке Бюхнера. Фильтрат представл ет собой раствор силиката натри .calcined at 550–700 ° C for 5–7 hours. Then the calcined diatomite is transferred to a thermostat and treated with a 2–8% solution of NaOH grade OCH 18–3 and, with stirring, {kept for 2–5 hours at 60–95 ° s Then, the resulting suspension is filtered on a Buchner funnel. The filtrate is a sodium silicate solution.
