Description
Известно, что процесс окислени углеводородов , с целью получени синтетических кислот, можно проводить в несколько стадий.It is known that the process of oxidation of hydrocarbons, in order to obtain synthetic acids, can be carried out in several stages.
Авторами насто щего изобретени предлагаетс этот процесс вести в две фазы, нейтрализу содой после первой стадии окислени полученные кислоты, после чего вновь производить окисление . При второй фазе процесса происходит окисление ангидридов и дезодораци запаха продуктов.The authors of the present invention propose this process to be carried out in two phases, neutralizing soda after the first stage of oxidation, the resulting acids, and then again producing oxidation. In the second phase of the process, the oxidation of anhydrides and the deodorization of the smell of products take place.
Пример. Дестиллаты нефти или минеральные масла, как таковые, или предварительно очищенные серной кислотой или сильно сульфированные дым щейс кислотой в первой стадии окисл ютс кислородом воздуха при нагревании в присутствии твердых или растворимых в масле катализаторов (окисей металлов, углекислых солей или растворимых солей металлов). Окисление продолжают до образовани приблизительно 10-20Vo кислот, этим оканчиваетс перва фаза окислени .Example. The distillates of petroleum or mineral oils, as such, either previously purified with sulfuric acid or heavily sulfated with fuming acid, are first oxidized with atmospheric oxygen when heated in the presence of solid or oil soluble catalysts (metal oxides, carbon salts or soluble metal salts). Oxidation is continued until the formation of approximately 10-20 Vo acids, the first oxidation phase ends.
В окисленное масло, при перемешивании воздухом и механической мешалкой , ввод т сухую кальцинированную соду или поташ с таким расчетом, чтобы произошла нейтрализаци свободных кислот.Dry acid soda or potash is added to the oxidized oil, with air and a mechanical stirrer, in order to neutralize the free acids.
При правильном ведении операции,With proper maintenance of the operation,
(И8)(I8)
после нейтрализации получаетс легко подвижное масло, которое при 115-130 хорошо перемешиваетс . После нейтрализации , не отдел мыл, ведут вторую фазу окислени . При этой операции происходит окисление ангидридов и дезодораци запаха солей кислот. Содержащее мыла масло после окислени дл целей извлечени мыл и свободных кислот обрабатываетс раствором водной или водно-спиртовой или спиртовой щелочи или подвергаетс экстракции легкокип щими спиртами и водными растворами.after neutralization, an easily mobile oil is obtained, which at 115-130 is well mixed. After neutralization, not the soap section, the second phase of oxidation is carried out. During this operation, the oxidation of anhydrides and deodorization of the smell of salts of acids occurs. After oxidation, the oil containing soap is extracted with a solution of aqueous or aqueous-alcoholic or alcoholic alkali or subjected to extraction with low-boiling alcohols and aqueous solutions after oxidation for the extraction of soaps and free acids.
В некоторых случа х, когда хот т иметь кислоты, не содержащие окиси кислот, масло после двойного окислени обрабатываетс водными растворами серной или сол ной кислот, промываетс водой, высушиваетс хорошим отстаиванием или продуванием воздуха и подвергаетс дестилл ции перегретым паром .In some cases, when acid-free acids are desired, the oil after double oxidation is treated with aqueous solutions of sulfuric or hydrochloric acids, washed with water, dried by good sedimentation or air blowing and subjected to distillation with superheated steam.
Из полученного дестилл та обработкой водным раствором щелочей извлекают кислоты в виде соли.Acids in the form of a salt are extracted from the obtained distillate by treatment with an aqueous solution of alkalis.
Предмет изобретени .The subject matter of the invention.
Способ получени синтетических кислот путем окислени минеральных масел в присутствии катализаторов в две фазы.A method of producing synthetic acids by oxidizing mineral oils in the presence of catalysts in two phases.
отличающийс тем, что окисленное масло до определенного содержани кислот нейтрализуют содой и подвергают вторичному окислению без выделени мыл, после чего масла обрабатывают обычным образом.characterized in that the oxidized oil is neutralized to a certain content of acids with soda and subjected to secondary oxidation without isolation of soaps, after which the oils are processed in the usual manner.
