Description
Известен способ удалени ртути из растворов антрахинон-1-сульфокислоты в разбавленной ниже 20°Ь серной кислоте с помощью железа или меди.There is a known method for removing mercury from solutions of anthraquinone-1-sulfonic acid in sulfuric acid diluted below 20 ° L with iron or copper.
По описываемому способу удаление ртути осуществл етс в присутствии малых количеств антрахинона, при этом ртуть выде.т етс в виде тонкодисперсных частиц, сорбируемых кристаллами антрахинона.According to the described method, mercury removal is carried out in the presence of small amounts of anthraquinone, while mercury is released as fine particles sorbed by anthraquinone crystals.
Особенность способа заключаетс в том, что в раствор до начала выделени ртути ввод т антрахиноп или сохран ют его в растворе в количестве , близком к весу ртути, содержащейс в растворе.The peculiarity of the method is that anthraquinop is introduced into the solution before the release of mercury or is kept in solution in an amount close to the weight of mercury contained in the solution.
Дл фильтрации реакционной массы примен ют, патронный фильтр, СОСТОЯШ.ИЙ из кислотостойких, непроницаемых дл тонкодисперсных осадков элементов, например фторопластовых «свечей.For filtering the reaction mass, a cartridge filter is used consisting of acid-resistant elements impermeable to fine precipitation, for example, fluoroplastic candles.
Пример 1. К 200 л раствора антрахинон-1-сульфокпслоты, содержащего ПО г ртути в виде соли минеральной кислоты, прибавл ют 100-150 г антрахинона, подогревают смесь до температуры не выше 60 и при иеремещивании ввод т железо или медь в виде норопжа или стружки в количестве, превышающем теоретически необходимое в полтора-два раза. Через 20-30 мин выделившийс осадок отфильтровывают .Example 1. To 200 l of an anthraquinone-1-sulfonic solution containing PO g of mercury in the form of a mineral acid salt, 100-150 g of anthraquinone are added, the mixture is heated to a temperature not higher than 60, and when shifting, iron or copper is introduced shavings in quantities exceeding the theoretically required one and a half to two times. After 20-30 minutes, the precipitated precipitate is filtered.
Пример 2. К 200 л раствора антрахинон-1-сульфокислоты, неполностью отфильтрованного от непрореагировавщего аитрахинона и содержащего последнего примерно 100-150 г, прибавл ют при температуре не выше 60 железо или медь в виде порошка или стружки и далее поступаю .т, как в примере 1.Example 2. To 200 l of anthraquinone-1-sulfonic acid solution, which was not completely filtered from unreacted nitraquinone and containing the latter, about 100-150 g, iron or copper in the form of powder or chips was added at a temperature not exceeding 60, and then fed as in example 1.

Предмет изобретени Subject invention
Способ удалени ртути из растворов антрахинон-Ьсульфокислоты в разбавленной ниже 20% серной кислоте с помощью железа или меди, отличающийс тем, что в раствор до начала выделени ртути ввод т антрахинон или сохран ют его в количестве, близком к весу ртути, содержащейс в растворе.A method for removing mercury from solutions of anthraquinone-L sulfonic acid in sulfuric acid diluted below 20% by means of iron or copper, characterized in that anthraquinone is added to the solution before the release of mercury or is kept in an amount close to the weight of mercury contained in the solution.
