Description
{6-7 ч) и необходимости нейтрапизации избытка серной киспоты.(6-7 h) and the need to neutralize the excess sulfuric acid.
Цепь изобретени - повышение степени раапожени тиосупьфата натри и упрощение процесса.The chain of the invention is an increase in the degree of dilution of sodium thiosupatum and simplification of the process.
Поставпенна цепь достигаетс тем, что раствор тиосупьфата натри обрабатьгоают серной кислотой в присутствии сероводородсодержащего газа, вз того в копичестве двух - трех молей сероводорода на один моль тиосульфата, .натри . Указанное отпичие позвоп ет практически погшостыо разпожить тиосупьфат натри , снизить при этом энергозатраты и упростить процесс за счет разпожени тиосупьфата натри при комнатнойThe supply chain is achieved in that the sodium thiosupatate solution is treated with sulfuric acid in the presence of hydrogen sulfide-containing gas, taken as a quantity of two to three moles of hydrogen sulfide per mole of thiosulfate, sodium. This step allows virtually sodium nitrosupate, reduces the energy consumption and simplifies the process by decomposing sodium titiosipate at room temperature.
температуре с испопьзованием серной киспоты дюбой концентрации.temperature with the use of sulfuric acid concentration concentration.
Сущность способа состоит в спедукэдем.The essence of the method consists in spedukedam.
В исходный.раствор тиосупьфата натри добавл ют при перемешивании стехиометрическое количество серной киспоты, В процессе взаимодействи реагентов в систему ввод т сероводородсодержащий газ в копичестве соответствующем .отношению двух - трех сероводорода на один мопоь тиосупьфата до достижени нейтральной реакции раствора . Обработку провод т при комнатной температуре . Продолжительность процесса 5 минWith the stirring, a stoichiometric amount of sulfuric acid is added to the initial sodium thiosupatate solution. In the process of reacting the reactants, hydrogen sulfide-containing gas is introduced into the system in an amount corresponding to the ratio of two to three hydrogen sulfide to one polythipatylate until a neutral solution of the solution is reached. The treatment is carried out at room temperature. Duration 5 min
По достижении нейтральной реакции ток прекращают и раствор нагревают, либо продувают дл освобождени его от избытка Н , а затем упаривают дл When a neutral reaction is reached, the current is stopped and the solution is heated or rinsed to free it from excess H and then evaporated to
коагул ции и поспедувоцего выделени серы и товарного сульфата натри известным путем.the coagulation and sedation of sulfur and salable sodium sulfate in a known manner.
Пример. Раствор тиосульфата натри концентрацией г/л одновременно обраба .тывают серной киспотой и сероводородсодержащим газом до нейтральной реакции раствораРасход 50%-ной серной киспоты по стехиометрии, расход сероводородсодержащего газа 3 моль на 1 моль тиосульфата натри в растворе при скорости подачи-« 10 л/ч. Продолжительность процесса 5 мин.Example. A solution of sodium thiosulfate with a concentration of g / l is simultaneously treated with sulfuric acid and hydrogen sulfide-containing gas until the solution is neutral. The consumption of 50% sulfuric acid stoichiometry, the consumption of hydrogen sulfide-containing gas is 3 mol per 1 mol of sodium thiosulfate in solution at a feed rate of “10 l / h . The duration of the process 5 minutes
Степень разложени тиосульфата натри в растворе 99,6%.The decomposition rate of sodium thiosulfate in solution is 99.6%.
