The method involves treating the silica with water vapor in an amount of 3.5-10 ° C / o and then treating with phosphorus trichloride vapor. 1 tab. with so with so
Description
Изобретение относитс к неорганической химии, а именно к сиособам получени кремнезема .This invention relates to inorganic chemistry, namely to methods for producing silica.
Цель изобретени - упрощение способа ,The purpose of the invention is to simplify the method
Пример 1. Аэросил марки А-300 массой 2,0 г обрабатывали нарами воды до влажности 3,5°/о, загружали в лабораторный реактор и обрабатывали в парах треххлорис- того фосфора в течение 0,5 ч при 140°С. Продукты реакции удал ли вакуумированием при 140°С в течение 2 ч. Содержание фосфора в образце составило 2,7%.Example 1. A-300 aerosil with a weight of 2.0 g was treated with a batch of water to a moisture content of 3.5 ° / o, loaded into a laboratory reactor, and treated in trichlorine phosphorus vapors for 0.5 h at 140 ° C. The reaction products were removed by evacuation at 140 ° C for 2 h. The phosphorus content in the sample was 2.7%.
Пример 2. Аэросил марки А-3000 массой 2,0 обрабатывали парами воды до влажности 9,3%, загружали в лабораторный реактор и обрабатывали парами треххлорис- того фосфора нри 95°С в течение 2 ч. Затем продукты реакции удал ли вакуумированием при температуре реакции в течение 2 ч. Содержание фосфора составило 3,5°/о.Example 2. A-3000 grade Aerosil weighing 2.0 was treated with water vapor to a moisture content of 9.3%, loaded into a laboratory reactor and treated with trichlorine phosphorus vapors at 95 ° C for 2 hours. Then, the reaction products were removed by evacuation at a temperature reaction for 2 hours. The phosphorus content was 3.5 ° / o.
Пример 3. Белую сажу марки БС-100 увлажн ли парами воды до влажности 8,7%, затем загружали в лабораторный реактор и обработали парами треххлористо- го фосфора в течение 5 ч при 80°С. Содержание фосфора в образце составило 2,1%.Example 3. BS-100 brand white soot was moistened with water vapor to a moisture content of 8.7%, then loaded into a laboratory reactor and treated with phosphorus trichloride vapors for 5 hours at 80 ° C. The phosphorus content in the sample was 2.1%.
Пример 4. Аэросил марки А-3000 в количестве 20 кг загружали в промышленныйExample 4. Aerosil brand A-3000 in the amount of 20 kg was loaded into industrial

эмалированный реактор, продували азотом дл удалени кислорода воздуха из реактора , нагревали до 130°С и ввели 2 л воды. Обработку вели в течение 0,5 ч. Затем вthe enameled reactor was purged with nitrogen to remove the atmospheric oxygen from the reactor, heated to 130 ° C, and 2 liters of water were injected. The treatment was carried out for 0.5 hours. Then in
реактор подавали 3,6 кг треххлористого фосфора и реакцию проводили в течение 2 ч при 130°С. Продукты реакции удал ли отдувкой азотом в течени.е 2 ч при 130°С. Содержание фосфора в образце составило 4%.the reactor was fed 3.6 kg of phosphorus trichloride and the reaction was carried out for 2 hours at 130 ° C. The reaction products were removed by stripping with nitrogen for 2 hours at 130 ° C. The phosphorus content in the sample was 4%.
Результаты примеров осуществлени способа по примерам 1-4 и известному сведены в таблицу.The results of the examples of the implementation of the method according to examples 1-4 and known are tabulated.
Преимуществом предлагаемого способа вл етс исключение операции сушки кремнезема и снижение температуры реакции при сохранении полноты содержани фосфора в продукте.The advantage of the proposed method is the elimination of the operation of drying the silica and lowering the reaction temperature while maintaining the full phosphorus content in the product.
