Description
Известные способы получени смол ного сорбента не обеспечивают достаточно высокой кислотостойкости и высокой сорбционной емкости .Known methods for producing resin sorbent do not provide a sufficiently high acid resistance and high sorption capacity.
По предложенному способу полистирол или соиолимеры стирола с диаллиловыми эфирами малеиновой и фталевой кислот подвергают сульфированию концентрированной серной кислотой, что придает сорбенту высокую кислотостойкость и высокую сорбционную емкость.According to the proposed method, polystyrene or styrene soiolimers with diallyl esters of maleic and phthalic acids are subjected to sulfonation with concentrated sulfuric acid, which gives the sorbent high acid resistance and high sorption capacity.
Кислотостойкие сорбенты получают на основе полистирола.Acid-resistant sorbents are based on polystyrene.
Пример 1. Водно-эмульсионный полистирол нагревают с трехкратным количеством концентрированной серной кислоты при беспрерывном перемешивании. Нагревают на масл ной бане, температура которой ие превышает 130°. Нагревание ведут до получени однородного продукта темно-бурой окраски. Смесь разбавл ют водой, нейтрализуют разбавленным раствором щелочи и тщательно промывают- Отмытый от следов соли сульфостирол сУщат при 130-140° до образовани черной блест щей смолы.Example 1. Aqueous emulsion polystyrene is heated with a threefold amount of concentrated sulfuric acid with continuous stirring. Heat in an oil bath, the temperature of which is less than 130 °. Heating is carried out to obtain a uniform product of dark brown color. The mixture is diluted with water, neutralized with a dilute alkali solution, and washed thoroughly. The sulfostrole, washed from the traces of salt, is saturated at 130-140 ° to form a black shiny resin.
Пример 2. Совместно полимеризуют стирол и диаллиловые эфиры , как например, диаллилмалеинат и диаллилфталат при соотношении 4:1 в процентах по весу. Полимеризацию производ т в присутствии перекиси бензола, как инициатора. Полученный неплавкий и нерастворимый в бензоле полимер сульфируют концентрированной серной кислотой при 120°, вз той в двухкратном количестве, в течение 8 часов. По лученный сорбент черного цвета с блест щим изломом не раствор етс в органических растворител х.Example 2. Together polymerized styrene and diallyl ethers, such as diallylmaleate and diallylphthalate at a ratio of 4: 1 in percent by weight. The polymerization is carried out in the presence of benzene peroxide, as an initiator. The resulting non-meltable and benzene-insoluble polymer is sulphured with concentrated sulfuric acid at 120 °, taken in two times, for 8 hours. The resulting black sorbent with a shiny fracture does not dissolve in organic solvents.
