Description

содержащих соединений в ней равно 76%. Разделение проведено в три стунени экстракции при соотношении экстрагент: сырье, равномcontaining compounds in it is 76%. The separation was carried out in three stuneni extraction with a ratio of extractant: raw materials equal to

На каждой ступени экстракции процент извлечени  кислородсодержащих соединений (в пересчете на исходный продукт) равен 85,5% 5,4% и 1,6%; таким образом, суммарна  степень извлечени  после трех ступеней экстракции при комнатной температуре равна 92,5%.At each stage of extraction, the percentage of extraction of oxygen-containing compounds (in terms of the starting product) is 85.5%, 5.4% and 1.6%; thus, the total recovery after three extraction steps at room temperature is 92.5%.

Пример 3. В качестве сырь  была вз та фракци  с началом кипени  160°С, полученна  при синтезе из СО и Н2, и содержаща  50,7% спиртов. Сырье подавалось в среднюю часть экстракционной колонны. В верхнюю часть колонны поступал диэтиленгликоль, а вниз колонны подавалась цетанова  фракци .Example 3. As a raw material, a fraction was taken with a boiling point of 160 ° C, obtained by synthesis from CO and H2, and containing 50.7% alcohols. Raw materials were fed to the middle part of the extraction column. Diethylene glycol was fed to the top of the column, and the cetane fraction was fed to the bottom of the column.

Содержание спиртов в экстракте составило 97%, при применении парафиновой углеводородной фракции 260-320°С вместо цетановой , содержание спиртов в экстракте составило 95%.The alcohol content in the extract was 97%, when using paraffin hydrocarbon fraction 260-320 ° C instead of cetane, the alcohol content in the extract was 95%.

1. Способ разделени  смеси углеводородов и кислородсодержащих продуктов, включающих соединени  Ci-Cg, отличающийс  тем, что, с целью наиболее полного разделени , процесс ведут путем экстракции кислородсодержащих соединений многоатомньпу спиртом (например, диэтиленгликолем) или пропиленкарбонатом.1. A method of separating a mixture of hydrocarbons and oxygen-containing products, including Ci-Cg compounds, characterized in that, in order to achieve the most complete separation, the process is carried out by extracting oxygen-containing compounds with polyatomic alcohol (for example, diethylene glycol) or propylene carbonate. 2. Способ по ц. 1, отличающийс  тем, что, с целью повышени  степени чистоты выдел емых продуктов, экстракцию ведут двум  несмешивающимис  растворител ми, один из которых (например, многоатомный спирт пли пропиленкарбонат) раствор ет кислородные соединени , а второй - (наиример, «-цетан или фракци  парафиновых углеводородов 260-320°С) раствор ет углеводороды.2. The method according to c. 1, characterized in that, in order to increase the purity of the separated products, extraction is carried out with two immiscible solvents, one of which (for example, a polyhydric alcohol or propylene carbonate) dissolves oxygen compounds, and the second (naimer, "-cetan or fraction paraffinic hydrocarbons 260-320 ° C) dissolves hydrocarbons.
