Description
Развитие методов окис.чени высокомолекул рных углеводородов д. 1 иолучени; карбоковых кис/ют находитс R пр мой зависимости от развити методов предварите, очистки иефтепродуктов. так как обычно дл окислени требуютс высокоочищенные исходные продукты. Очистка нефтепродуктов св зана со значительным расходом реагентов и это обсто те. ьство сил1)Но тормозит виедренне в промышленность окисленных продуктов.Development of methods for the oxidation of high molecular weight hydrocarbons d. 1 and obtaining; Carboxy acidic s / s is R directly dependent on the development of methods for pre-cleaning and petroleum products. since usually highly purified starting materials are required for oxidation. Refining of petroleum products is associated with a significant consumption of reagents and this is the case. Strength1) But it slows down viedrenno to the industry of oxidized products.
Предлагаетс способ окислени неочищенных нефтепродуктов, при котором очистка окисл емого сырь проходит в процессе самого окислени .A method for the oxidation of crude oils is proposed, in which the oxidized raw materials are purified during the oxidation process itself.
Сущность способа сводитс к следующему: неочищенное сырье с растворенным в нем го.могенным катализатором (нафтенат марганца) в количестве 0,2% закачиваетс в железный реактор (оксидатор) и продуваетс гор чим воздухом с температурой 160-170. Расход воздуха не должен быть меньше 1,5 л/час. При этом происходит быстрое образование карбенов и карбоидов за счет присутствующих в неочин1.енном сырье ненасыщенных соединений и нейтральных смол.The essence of the method is as follows: untreated raw materials with a homogenous catalyst (manganese naphthenate) dissolved in it in an amount of 0.2% are pumped into an iron reactor (oxidizer) and blown with hot air with a temperature of 160-170. Air consumption should not be less than 1.5 l / h. When this happens, the fast formation of carbenes and carboids occurs due to the unsaturated compounds and neutral resins present in the neo-syn. Raw materials.
Процесс образовани карбенов и других соединений ироходит за счет своеобразной направ.тенности реакции, обусловленной совместным действие.м катализатора и железной стенки аипарата. Подъем температуры свидетельствует о конце процесса окислительной очистки и объ сн етс возникновением экзотермической реакции образовани жирных кислот.The process of the formation of carbenes and other compounds is due to the peculiar direction of the reaction caused by the combined action of the catalyst and the iron wall of the unit. A rise in temperature indicates the end of the oxidative purification process and is explained by the occurrence of an exothermic fatty acid formation reaction.
Образование жирных кислот начинает проходить только после того , как все тормоз щие этот процесс соединени перейдут в нерастворимое состо ние. С началом повыщени температуры продувку воздухом заканчивают и продукт перекачивают в специальную емкость. Полученный таким способом продукт содержит от 8 до 15% твердого остатка и имеет очень невысокое кислотное число (1-4 мг КОН на 1 г продукта).The formation of fatty acids begins to take place only after all compounds inhibiting this process become insoluble. With the onset of temperature increase, air blowing is completed and the product is pumped into a special container. The product obtained in this way contains from 8 to 15% of the solid residue and has a very low acid number (1-4 mg KOH per 1 g of the product).
Вторым этапом очистки вл етс удаление твердого остатка -тThe second stage of purification is the removal of solid residue
