Cyclohexene distillation

A fraction containing primarily cyclohexene primarily cyclohexene and water is separated from raw cyclohexanone in Cyclohexene column. Raw Cyclohexanone is fed from storage tank to Cyclohexene Column via Cyclohexene heater.

In Cyclohexene Heater, the feed is heated up to about 1200C with the heat carried by the bottom product from Alcohols column. The Cyclohexene column is operated at atmospheric pressure and temperatures of 850C at top and 1650C at bottom. The vapours from Cyclohexene column, containing mainly Cyclohexene and water, are condensed in Cyclohexene condenser and Cyclohexene Cooler which are connected in series.

1.7 bar nitrogen is continuously directed to the vent of Cyclohexene Cooler. After separation the water layer is drained off to waste water vessel and the organic layer is pumped by reflux pump to the top of Cyclohexene column and rest as distillate to benzene hydrogenation section. Cyclohexene evaporator is fed with 20 bar steam. The bottom product from cyclohexene column is pumped by cyclohexanone pump as feed to Alcohols column. The Project Report On Cyclohexanone

    Reduction involves increasing the number of carbon hydrogen bonds by adding hydrogen across a double or triple bond which results in an increase in electron density at the carbon atom. Organic functional groups containing double and triple bonds which undergo reduction are unsaturated. The reduction of the double bond by addition of hydrogen atoms results in the product being fully saturated. Metal hydride reducing agents that have different reactivities toward specific functional groups are commonly used in chemical reductions.…

    Based on the theory of free volume, penetrant molecules can diffuse from one place to another if there is a blank space or a free volume sufficient (Mulder, 1991). The movement of heat will produce a magnification of free volume in the membrane. Therefore, the rate of diffusion of each molecule penetrant increased at high temperatures and produce high permeation flux values anyway (Bakhsi et al., 2006). Figure 4.9. The effect of temperature on selectivity for various of membrane composition and ethanol-water (30%-70%) Figure 4.10.…

    Ethyl vinyl ether was used to protect –OH on glycidol based on a literature reported protocal.59 In a typical procedure, 0.675 mol glycidol and 200 mL ethyl vinyl ether were loaded in a round-bottom flask, to which 1.25 g TsOH was then added. The reaction was allowed to proceed at room temperature (RT) for 3h. The resulting mixture was then purified by washing with 100 ml saturated aqueous solution of NaHCO3 for 3 times. The organic layer obtained was dried by MgSO4. After filtration of MgSO4, the excess ethyl vinyl ether was removed by rotary evaporation.…

    A possible chemical reason that this experiment yielded less than 100% cyclohexanone was due to the spontaneous decomposition of sodium hypochlorite, 2NaOCl = 2NaCl + O2, which decreased the amount of reactant present in the initial reaction when hypochlorous acid was formed, which was the oxidizing agent required to oxidize cyclohexanol into cyclohexanone. Sodium hypochlorite decomposed into O2 and NaCl due to a multitude of factors such as exposure to high temperatures, prolonged storage time or sunlight exposure. If a large enough quantity of the sodium hypochlorite was decomposed to limit the reaction that produced hypochlorous acid, the quantity of cyclohexanone produced may be affected. This would have resulted in a decrease in the production…

    As this condensate mixes with rising vapor and as the cycle undergoes, the vapor that rises should contain increasing amounts of this more volatile liquid. Therefore, leaving the less volatile liquid in the distillation flask. The temperature will not rise at the thermometer while the more volatile liquid is being fractioned because the main vapor that reaches this portion of the column should consist mainly of the lower boiling point liquid which should remain consistent until the vapor composition begins to change to that of the high boiling point liquid. Finally, once all of the more volatile liquid has been fractioned, the temperature will increase to that of the boiling point of the lower volatile liquid and the vapor that rises should primarily consist of the…

    This experiment was devised to discover the effect of Soil Salinity on the health of a Bald Cypress sapling. This is highly relevant to the people of Southeastern Louisiana. Ever since more land has begun to be lost, salt intrusion has affected the freshwater swamps causing Cypress Trees to die and continue the cycle of land loss ("Salt Tolerance of Southern Baldcypress"). This experiment’s results were to help the understanding of Cypress Tree salt tolerance and discover why the Cypress Swamps are struggling to recover.…

    Due to the results of our tests, we are pretty sure that our product is cyclohexene. Our product, cyclohexene, turned clear immediately when Br2 was added to it. Hexane only turned clear after sitting in a bright light for a long time. Cyclohexanol reacted quickly when the Br2 was added; it turned clear immediately. Our cyclohexene had a precipitate form when KMnO4 was added.…

    Purpose: The purpose of this laboratory was to synthesize isopentyl acetate, commonly known as banana oil, in a reaction of methanol and isopentyl alcohol catalyzed by sulfuric acid. Through this Fischer esterification reaction, it was possible to learn about using a Reflux condenser to run a reaction as well as purifying the product through various washes and extractions along with simple distillation. In addition, the product of the experiment was carefully analyzed based upon boiling point, physical characteristics, IR and 1H NMR. The overall objective was to successfully isolate the product of isopentyl acetate and observe the purity of this product.…

    Additionally, the distillate would still contain a mixture of the volatile components, rather than one pure component. In order to separate the volatile components with similar boiling points, multiple simple distillations would have to be performed on the first fraction of distillate obtained, each one producing a more pure sample of the more volatile component. Because this method is inefficient and yields a very low volume of the target solvent, fractional distillation is instead used to separate a mixture of volatile solvents with similar boiling points. Fractional distillation is a method of separation similar to simple distillation, in that volatile components of a solution are separated based on boiling point. The addition of an insulated column to the distillation apparatus in fraction…
