Vapor-Liquid Equilibrium: Binary System
Vapor-Liquid Equilibrium (VLE) unit can be utilized to learn about the binary system. The principle reason for this experiment is to determine the composition of cyclohexane and isopropyl alcohol (IPA) in the vapor stage and liquid stage. In the first mixture, we began with a pure liquid of IPA then we started to add different amount cyclohexane. The molar ratio of %IPA / %Cyclohexane was started with 100/0 until 60/40 was reached. In the second mixture, we started with pure liquid of cyclohexane then we began to add different amount of IPA in the mixture. The molar ratio of %Cyclohexane / %IPA was started with 100/0 until 75/25 was reached. The boiling point for IPA, Tbp=355.8 K, and cyclohexane, Tbp=353.9 K, are almost the same. Refractive

    The purpose of this experiment is to determine the boiling point of a liquid and the melting point of a solid. It is useful to know the melting point and boiling point of a substance to identify whether it is pure or not. I could learn how to determine the melting and boiling point of a substance through its temperature when the acetamide turned into a liquid and bubbles emerged from the capillary tube in the Isopropyl alcohol.…

    2-Methylcyclohexanol Dehydration

    The 2-methylcyclohexanol alcohol used in this experiment was a mixture of both cis and trans isomers. The way this reaction occurs is as follows. Through protonation, the acid-catalyst converts the already present, poor leaving group (-OH) to a much better leaving group (H2O+). Then once the H2O and the H+ are eliminated the reaction yields an alkene in which the un-protonated alcohol serves as the reaction solvent. This experiment then called for the distillation of this mixture, using a distillation apparatus. As this distillation took place the products, alkenes and water continuously distilled from the reaction mixture into a Hickman still as they were formed. The removal of these elements shifted the equilibrium to the right, ultimately increasing the yield of alkene, this is also known as Le Chatelier’s Principle. Then both fractions were washed with 1.5mL of 5% aqueous sodium bicarbonate, the reason or this is that the sodium bicarbonate gets rid of the excess acid present. In order to analyze the fractions, both were put through gas…

    Cyclohexane Lab Report

    The molar mass is determined by dissolving the unknown compound into a pure liquid with defined physical properties, in this case Cyclohexane. When dissolving a solute, it forms a homogeneous solution, in which the solvent of the solution physical properties are not longer defined, but depends on the amount of solute added. Whenever a substance is dissolved in a solvent, the vapor pressure decreases. When the vapor pressure decreases, it also lowers the boiling and freezing point of the solvent and increases the osmotic pressure. These four properties are known as the colligative properties, the magnitude of the changes depends on the amount of solute dissolve; the changes are directly proportional to each other. The higher the solute concentration, the higher the changes of vapor pressure, therefore, a lower freezing point. It is hypothesized that the freezing point temperature will decreased, if there is a higher concentration of the solid added to the…

    This paper reports a lab experiment done on the ideal gas law to determine differences in gas based upon their “R” constant difference to 0.082057. A total of seven gases were tested, which included, Ethanol, Hexane, Cyclohexane, Pentane, Ethyl Acetate, Butane and Acetone. These gases were each heated and then condensed to liquid gas to find specific values and determined Ethanol as the gas closest to ideal behavior in this experiment.…

    Essay On Distillation And Gas Chromatography

    The goal of this experiment was to separate Toluene and Hexane by distillation and gas chromatography based on their difference in boiling points. The boiling point of hexane is 69 degrees Celsius and the boiling point of toluene is 110 degrees Celsius. Three fractions were collected for both simple and fractional distillation. The first fraction was hexane since it had the lower boiling point. The second fraction was a mixture of toluene and hexane. The third fraction was toluene since it had the high boiling point of 110 degrees Celsius. Gas chromatography was also preformed on each of the fractions from simple and fractional distillation. In the gas chromatography process, the compounds are carried through a stationary phase, and pushed…

    Alkyl Halide: A Nucleophilic Substitution Reaction

    Physical Properties- the physical properties were not the main source for determining the identity of the alkyl halide and starting alcohol because of the usual inaccuracy, however the results for boiling point and density proved close to 2-bromobutane and 2-Butanol. The boiling range from the week one experiment was 76-118 ◦C, which was too large of a range and the alkyl halide had not been completely purified. However, the boiling point for 2-butanol alcohol was about 83 ◦C, which lies within the range of the starting boiling range.…

    40ml of an equimolar mixture of cyclohexane and toluene was obtained and transferred into a 100ml round bottomed boiling flask which contained boiling chips. The distilling column was packed with metal sponge and the height was measured in centimeters and recorded. The distillation apparatus was assembled and a heat mantle was set. Several vials were used as fraction receivers. The vials were labeled, 1-4, and weighed prior to adding the liquid mixture and after the liquid was added. The temperature was recorded before adding heat in order to begin distillation (20º C). The temperature was recorded prior to each distillation fraction and after each 2ml of distillate which was recorded in table 1. The system was turned off and cooled down letting the remaining condensed vapor drain into the round bottomed flask. This sample was transferred by pipette into a vial…

Two trials were completed on each sample. The results were then categorized and combined with other data sets collected by the laboratory students. This data was then used to find the eutectic point of the two substances…

    The purpose of doing this experiment is to separate a sample of cyclohexane and toluene using simple miniscale distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are acquired during the distillation process. It is expected that cyclohexane boils and distils before toluene. By gathering these measurements will allow us to determine refractive index of fractions collected. An Abbe refractometer will be used to accomplish this.…
