    Through both simple and fractional distillation an equimolar solution of ethyl acetate and propyl acetate was seperated. After distilling 20 mL of the mixture the samples were collected in fractions, which were then analyzed using gas chromatography. The mole ratios of the distillations were converted to a percentage to analyze percent composition. Simple distillation yielded the following results: S1- 69.88% EA/ 30.12% PA, S2- 66.73% EA/ 33.27% PA, and S3- 46.42% EA, 53.58% PA. Fractional distillation yielded: F1- 82.66% EA/ 17.34% PA, F2- 79.89% EA/ 20.11% PA, F3- 44.50% EA/ 55.50% PA, and 5.65% EA/ 94.35% PA. Comparing S1 to F1 and S2 to F2 shows fractional distillation yields better seperation of the components, giving a higher concentration of the more volatile ethyl…

    Fractional Distillation: Lab Report Mixtures can be seen just about anywhere. Mixtures are a substance made of two or more substances. A substance is a particular kind of matter that is uniform throughout. When these substances are mixed together and only mix physically and not chemically, like in a reaction, they are mixtures. Due to these properties, the substances within the mixture can be separated again. Mixtures are separated by one of many separation techniques. Take filtration of tap…

    Simple distillation was used for a liquid whose boiling points is 25 degrees Celsius over the other liquid, whereas fractional distillation is used for liquids with boiling points that are closer than 25 degrees Celsius apart. To obtain the highest percent ethanol, fraction distillation is proven to be the most effective. Because the 2 liquids have a boiling point difference of about 25 degrees Celsius, we used both simple and fractional distillation to remove the ethanol from the water.…

    Abstract: Distillation is the process of vaporizing a substance or a mixture; condensing it through the water condenser and then collecting it in the receiving flask1. In this experiment, fractional distillation is used to separate organic compounds that have a minuscule difference of their boiling points. The objective of this experiment is to purify and separate ethanol and water by fractional distillation to achieve the 95% of ethanol and 5% of water; then determine…

    DISTILLATION The purpose of experiment 1, fractional distillation and gas chromatography, was to separate an unknown organic mixture into two liquids. The primary process of separation was fractional distillation, which utilizes the physical properties of the two unknown volatile liquids. Once the unknown mixture was successfully fractioned, gas chromatography was used to help determine the identity of the two unknown liquids. Fractional distillation and simple distillation both take advantage…

    Experiment 1 sought to separate a binary solution into two fractions and determine the identity of the components. This is accomplished through distillation which is the separation of a mixture of compounds. There are two types of distillation; simple and fractional. Simple distillation is used when separating liquids and solids or between liquids with boiling points that differ by more than 40-50°C. On the other hand, fractional distillation separates two volatile liquids in order to achieve…

    The separation of mixtures to obtain pure products is done through a technique called distillation. This lab looks at two different distillation techniques, simple and fractional. Acetone and butanone were mixed together and then put through the distillation process in order to obtain each as a pure substance. These substances were boiled into vials that gave us fractions #1-4. Fraction #1 was obtained through simple distillation and fractions #2-4 were obtained through fractional distillation.…

    The dehydration of Cyclohexanol requires going through an acid-catalyzed elimination of water for the synthesis of cyclohexane from cyclohexanol. To get cyclohexane from cyclohexanol you must remove the cycloalkane with fractional distillation, drying with anhydrous sodium sulfate, and analyzed by GC data and the bromine test. The reaction we are trying to accomplish going from cyclohexanol to cyclohexene is a secondary alcohol going through an E1 reaction. This is the unimolecular…

    boiling point increases, the vapor pressure decreases. Distillation refers to the process of separating a mixture of liquids based on the differences between their boiling points. (Distillation Lecture, Canvas). However, this is only effective if the boiling points are significantly different. In this experiment, we are comparing hexane and toluene which having boiling points of 69 degrees Celsius and 111 degrees Celsius, respectively. Below is a representation of each molecular compound: …

    After starting with 30 mL of an unknown mixture of two solvents, fractional distillation and gas chromatography were used to identify the unknowns as acetone and toluene in a 1 to 2.04 ratio of acetone to toluene. Fractional distillation was first used to separate the unknown mixture into its components based on boiling point. Distillation refers to the method of separating components of a mixture through heating and cooling. Simple distillation, which is especially useful in the separation…
