Изобретение относитс к способам химической обработки глинистых растворов.The invention relates to methods for the chemical treatment of clay solutions.
Известны способы химической обработки глинистых растворов путем введени синтетических реагентов - стабилизаторов, таких как акриловые полимеры 1.Methods are known for the chemical treatment of clay solutions by introducing synthetic reagents - stabilizers, such as acrylic polymers 1.
Наиболее близким решением к предлагаемому вл етс способ химической обработки глинистых растворов путем введени в качестве реагента-стабилизатора гидролизованного продукта отходов производства волокна «Нитрон К-9 2.The closest solution to the proposed one is a method of chemical processing of clay solutions by introducing the waste of fiber production Nitron K-9 2 as a stabilizing agent of a hydrolyzed product.
Недостатком этого способа вл етс то, что в услови х высоких температур (200°С) и солевой агрессии (20% NaCl и 2% CaCl2) происходит деструкци полимера К-9, что ведет к потере стабилизирующих свойств, т. е. величина водоотдачи, толщина глинистой корки значительно возрастают и система расслаиваетс .The disadvantage of this method is that under conditions of high temperatures (200 ° C) and salt aggression (20% NaCl and 2% CaCl2), polymer K-9 is destroyed, which leads to a loss of stabilizing properties, i.e., water loss , the thickness of the mudcake increases significantly and the system stratifies.
Целью изобретени вл етс повышение термосолестойкости глинистых растворов за счет предохранени реагента-стабилизатора от деструкции.The aim of the invention is to increase the thermo solubility of clay solutions by protecting the stabilizer reagent from degradation.
Поставленна цель достигаетс введением продукта конденсации антраниловой кислоты с фенолом в присутствии формальдегида и сульфита натри .The goal has been achieved by introducing a product of condensation of anthranilic acid with phenol in the presence of formaldehyde and sodium sulfite.
Этот способ позвол ет повысить термостойкость глинистых растворов (NaCl - 20% и This method allows to increase the heat resistance of clay solutions (NaCl - 20% and
CaCls - 2%, при 200°С) при малом расходе реагентов.CaCls - 2%, at 200 ° C) with a low consumption of reagents.
Результаты обработки глинистых растворов по данному способу приведены в таблице.The results of the processing of clay solutions in this method are given in the table.
Продукт конденсации антраниловой кислоты с фенолом в присутствии формальдегида и сульфита натри синтезировалс следующим образом: в трехгорловую колбу, снабл енную холодильником с механической мешалкой, загружают последовательно антраниловую кислоту , фенол и сульфит натри в соотношении 0,5: 1:1, перемешивают в течение 15 мин. После чего загружают 1,5 мол формалина, включают обогревание; при достижении 70°С в реакционную колбу загружают остальное количество формалина (1,5 мол.). Смесь выдерживают при 95-98° С в течение 1,5 ч.The condensation product of anthranilic acid with phenol in the presence of formaldehyde and sodium sulfite was synthesized as follows: Anthranilic acid, phenol and sodium sulfite were mixed in a ratio of 15: 1 in a three-necked flask equipped with a mechanical stirrer cooler. min Then load 1.5 mol of formalin, include heating; when it reaches 70 ° C, the rest of formalin (1.5 mol.) is charged to the reaction flask. The mixture is maintained at 95-98 ° C for 1.5 hours
В результате реакции конденсации получаетс водорастворимый полимер в виде 50%ной насты темно-коричневого цвета.As a result of the condensation reaction, a water-soluble polymer is obtained in the form of a 50% dark brown infusion.
На ИК-спектрах полимера АПЩ имеютс следующие полосы: 3400-3200 см- (ОН), 2930, 1700 см-1 (СН2, СН), 1740 см (COONa), 1350, 1280см-i (NH), 1151, 1365см-i (SOa) и 1520,1620 см- (ароматическое дро).The IR spectra of the APSch polymer exhibit the following bands: 3400-3200 cm- (OH), 2930, 1700 cm-1 (CH2, CH), 1740 cm (COONa), 1350, 1280cm-i (NH), 1151, 1365cm- i (SOa) and 1520,1620 cm- (aromatic draw).
Водорастворимый полимер - продукт совместной конденсации фенола н антраниловой кислоты в присутствии формалина и сульфита натри хорошо раствор етс в воде. Водные растворы провод т электрический ток, удель34The water-soluble polymer — the product of co-condensation of phenol on anthranilic acid in the presence of formalin and sodium sulfite — dissolves well in water.
