Abstract
Description
Изобретение относится к нефтеперерабатывающей и нефтехимической промышленности, а именно к способу получения присадки к дизельному топливу, обладающей комплексным действием (повышение цетанового числа и уменьшение диаметра пятна износа). В качестве сырья для получения присадки комплексного действия (ПКД) используют фракцию, кипящую в пределах 190°С - К.К., выделенную из кубового остатка производства бутиловых спиртов (КОБС), получаемых методом оксосинтеза, и содержащую 1,0-6,0% спиртов C8H19OH, и 94-99% высококипящих компонентов, в том числе высших жирных спиртов. Фракцию нитруют нитрующей смесью азотной и серной кислот при температуре 0-10°С в течение 1,5 часов.The invention relates to the refining and petrochemical industries, and in particular to a method for producing additives to diesel fuel having a complex effect (increasing the cetane number and reducing the diameter of the wear spot). As a raw material for obtaining a complex action additive (PCD), a fraction boiling within 190 ° C is used - K.K., isolated from the bottom residue of the production of butyl alcohols (BACS) obtained by oxosynthesis, and containing 1.0-6.0 % alcohols C 8 H 19 OH, and 94-99% high boiling components, including higher fatty alcohols. The fraction is nitrated with a nitrating mixture of nitric and sulfuric acids at a temperature of 0-10 ° C for 1.5 hours.
Наиболее близкими по технической сущности являются способы получения цетанповышающих присадок, основанные на нитровании 2-этилгексанольных фракций кубового остатка бутиловых спиртов:The closest in technical essence are methods for the preparation of cetane-raising additives based on nitration of 2-ethylhexanol fractions of bottoms of butyl alcohols:

Пример получения присадки. Пример получения присадки. В реактор, снабженный мешалкой и охлаждающей баней, при температуре 0-5°С загружают 17 г азотной кислоты концентрации 70 мас. %, 29 г серной кислоты концентрации 94,8 мас. %. В полученную нитрующую смесь добавляют 2 г карбамида. В качестве сырья для нитрования использована фракция 190°С-КК следующего состава:An example of obtaining additives. An example of obtaining additives. In a reactor equipped with a stirrer and a cooling bath, at a temperature of 0-5 ° C, 17 g of nitric acid of a concentration of 70 wt. %, 29 g of sulfuric acid concentration of 94.8 wt. % To the resulting nitrating mixture was added 2 g of urea. As a raw material for nitration, a 190 ° С-КК fraction of the following composition was used:
- Спирты С8 (2-этилгексанол, 2-этил-4-метилпентанол и др.), 1,0-6,0 % масс.;- Alcohols C8 (2-ethylhexanol, 2-ethyl-4-methylpentanol, etc.), 1.0-6.0% of the mass .;
- Высококипящие компоненты, в т.ч. жирные спирты, 94,0-99,0 % масс..- High boiling components, incl. fatty alcohols, 94.0-99.0% of the mass ..
В реактор с нитрующей смесью со скоростью 0,1-0,15 мл/мин, при температуре 0-10°С вводится (дозируется) указанная фракция в количестве 20,0 г. После введения всего ее количества в реакционную смесь при непрерывном перемешивании выдерживают при температуре 0-10°С в течение 1-1,5 часов. По окончании процесса нитрования и расслоения реакционной смеси отработанные кислоты отделяют от органического слоя продукта нитрования.The specified fraction in the amount of 20.0 g is introduced (dosed) into the reactor with the nitrating mixture at a speed of 0.1-0.15 ml / min, at a temperature of 0-10 ° C. After introducing the entire amount into the reaction mixture with continuous stirring at a temperature of 0-10 ° C for 1-1.5 hours. At the end of the nitration process and the separation of the reaction mixture, the spent acid is separated from the organic layer of the nitration product.
Для промывки органического слоя используется вода в количестве по 50 см3 трижды.For washing the organic layer, water is used in an amount of 50 cm 3 three times.
При воздействии нитрующей смеси параллельно протекают 3 реакции:When exposed to a nitrating mixture, 3 reactions proceed in parallel:
При воздействии нитрующей смеси параллельно протекают 3 реакции:When exposed to a nitrating mixture, 3 reactions proceed in parallel:
О наличии нитроэфирных и карбоксильных групп свидетельствует ИК-спектр продукта: имеются полосы поглощения при 1270-1280 см-1 и 1620-1630 см-1, соответствующие симметричным и ассиметричным валентным колебаниям N=O группы, а также полоса поглощения при 865 см-1 (деформационные N-O) являются характерными для нитроэфиров. Полоса поглощения при 1760 см-1 (-СООН) является характерной для карбоновых кислот. Также о содержании карбоновых кислот в продукте свидетельствует кислотное число КЧ=40-45 мг КОН/г по ГОСТ 5985-79.The IR spectrum of the product indicates the presence of nitroester and carboxyl groups: there are absorption bands at 1270-1280 cm -1 and 1620-1630 cm -1 corresponding to symmetric and asymmetric stretching vibrations of the N = O group, as well as an absorption band at 865 cm -1 (deformation NO) are characteristic of nitroesters. The absorption band at 1760 cm −1 (—COOH) is characteristic of carboxylic acids. Also, the acid number CN = 40-45 mg KOH / g according to GOST 5985-79 indicates the content of carboxylic acids in the product.
Установлено, что полученная по вышеописанному способу присадка в связи с содержанием в готовом продукте нитроэфиров и жирных кислот, проявляет одновременно цетаноповышающие и противоизносные свойства (табл. 1).It was established that the additive obtained by the above method in connection with the content of nitroesters and fatty acids in the finished product exhibits both cetane-enhancing and anti-wear properties (Table 1).
Наиболее близкими по действию являются 2-этилгексилнитрат. Известно применение 2-этилгексилнитрата в качестве цетанповышающей присадки в количестве 0,1-1,0%.The closest in action are 2-ethylhexyl nitrate. It is known to use 2-ethylhexyl nitrate as a cetane enhancing additive in an amount of 0.1-1.0%.
Однако, как и сам 2-этилгексилнитрат, так и присадки на основе 2-этилгексанолсодержащих фракций при добавлении в ДТ, ухудшают его смазывающие свойства (НПиНХ, №4, 2012, с. 24-26).However, both 2-ethylhexyl nitrate itself and additives based on 2-ethylhexanol-containing fractions when added to diesel fuel impair its lubricity (NPiNKh, No. 4, 2012, pp. 24-26).
Данный недостаток приводит к необходимости внесения противоизносных присадок (ПИП), содержащих талловые, монокарбоновые и/или полициклические кислоты.This drawback leads to the need for anti-wear additives (PIP) containing tall, monocarboxylic and / or polycyclic acids.
Также известна присадка к ДТ комплексного действия (пат. РФ №2320706 (Сулейманов Р.С., Ставицкий В.А., Кабанов О.П. и др., опубликовано 27.03.2008, бюлл. №9)), содержащая, % масс: алкил(С3-С20)нитрат до 55, алкил(С1-С25)сукцинимид 0,1-10, сополимер высших эфиров С6-С25 акриловой или метакриловой кислоты с этиленненасыщенным мономером до 60, непредельная жирная кислота (олеиновая, линолевая или линоленовая) или ее амид до 100. Технический результат - при добавлении 0,01-1,0 мас.% присадки, наблюдается улучшение пусковых, низкотемпературных характеристик, а также смазывающих свойств ДТ. Отличающаяся тем, что в предлагаемом нами способе используется одно сырье, а в рассмотренном примере композиция присадки достигается смешением компонентов.Also known is the additive to DT of complex action (US Pat. RF No. 2320706 (Suleymanov R.S., Stavitsky V.A., Kabanov O.P. et al., Published March 27, 2008, bull. No. 9)), containing,% masses: alkyl (C 3 -C 20 ) nitrate up to 55, alkyl (C 1 -C 25 ) succinimide 0.1-10, copolymer of higher esters of C 6 -C 25 acrylic or methacrylic acid with an ethylenically unsaturated monomer up to 60, unsaturated fatty acid (oleic, linoleic or linolenic) or its amide up to 100. Technical result - when adding 0.01-1.0 wt.% additives, there is an improvement in starting, low temperature characteristics, as well as lubricants properties of diesel fuel. Characterized in that in our method we use one raw material, and in the considered example, the additive composition is achieved by mixing the components.
Эффективность присадки при добавлении в дизельное топливо г/о зимнее иллюстрируется следующими примерами:The effectiveness of the additive when adding winter diesel to diesel fuel is illustrated by the following examples:
*СДПИ - скорректированный диаметр пятна износа* SDPI - adjusted wear spot diameter
При добавлении присадки в ДТ г/о зимнее в количестве от 0,1 % масс. до 1,0 % масс., наблюдается прирост цетанового числа при одновременном существенном снижении ДНИ. При этом при внесении 1,0% ПКД достигается соответствие дизельного топлива ГОСТ Р 52386 - 200.When adding additives to the diesel fuel, winter is in an amount of from 0.1% of the mass. up to 1.0% wt., there is an increase in the cetane number with a simultaneous significant decrease in DAYs. At the same time, with the introduction of 1.0% PKD, the compliance of diesel fuel with GOST R 52386-200 is achieved.
