Description
Известный способ разделени моно- и диолефиновых углеводородов с п тью ЗТлсроднылти атомами в цели (фракции Cs) в безводном ацетоНитриле не эффективен и :по раздел ющей способности значительно уступает водному ацетонит рилу.The known method for the separation of mono- and diolefinic hydrocarbons with five ZT hydroxy atoms for a target (Cs fraction) in anhydrous acetonitrile is not effective and: in terms of their separating ability, it is much inferior to aqueous acetonitrile.
Предлагаетс онособ .разделени методом экстрактивной дистилл ции олефинов и диеновых углеводородов фракции С с применением ft качестве растворител Водного ацетонитрила, содержащего 10-20% вес. воды.An on-line method is proposed for the method of extractive distillation of olefins and diene hydrocarbons of fraction C using ft as solvent Aqueous acetonitrile containing 10–20% by weight. water.
Предлагаемый в способе, в качестве растворител , водный ацетонитрИЛ упрощает процесс экстрактивной дистилл ции, уменьщает потери , улучшает качество продукта и представа ет промышленный интерес.The aqueous acetonitrile proposed in the process as a solvent simplifies the process of extractive distillation, reduces losses, improves the quality of the product, and is of industrial interest.
Экстрактивную дистилл цию углезодородны-х смесей фракций Сз провод т в присутствии водного ацетонитрила при температуре 90° и давлении 4 ати.The extractive distillation of carbon-hydrogen mixtures of Cz fractions is carried out in the presence of aqueous acetonitrile at a temperature of 90 ° and a pressure of 4 MPa.
Относительна летучесть дл наиболее трудной пары 2-метилбутан2-изопрен составила 1,62 лри растворимости углеводородов равной 15,9% вес.The relative volatility for the most difficult pair of 2-methylbutan2-isoprene was 1.62% and the solubility of hydrocarbons is 15.9% by weight.
Сравнительно низка температура кипени ацетонитрила (82° и его азеотропной смеси с водой 76°) значительно уменьщит терМИческую полимеризацию диенових углеводородов, что св зано с сокращением потерь и улучшением качества продукта.The relatively low boiling point of acetonitrile (82 ° and its azeotropic mixture with water 76 °) significantly reduces the thermal polymerization of dienic hydrocarbons, which is associated with reduced losses and improved product quality.
Предмет изобретени Subject invention
Способ разделени углеводородных смесей фракции СБ с выделением высококонцентрированного изопрена методоМ, экстрактивной дистилл ции в присутствии ацетоиитрила, отличающийс тем, что, с целью увеличени эффективности разделени , примен ют водный ацетонитрил.The method of separation of hydrocarbon mixtures of the SB fraction with the release of highly concentrated isoprene by the method of extractive distillation in the presence of acetoiitrile, characterized in that, in order to increase the efficiency of separation, aqueous acetonitrile is used.
