Abstract

Distillation is the separation of a mixture into its component due to the difference in boiling point. In this experiment the group made use of Gin manufactured by Ginebra San Miguel as a test sample for two different techniques of distillation. The techniques used were simple distillation and fractional distillation and was carried out by two groups, simple distillation for the odd number group and fractional distillation for the even number group. The distillates are then subjected to a flammability test and the data gathered was used to calculate the percentage alcohol, error and loss. The data gathered from temperature readings were graphed. It was found that fractional distillation is more efficient compared to simple distillation based on the calculated results.

Introduction

Distillation is a method used to purify a mixture by separating the component from a less-volatile component due to the differences in boiling point. If the compound is known to be more volatile than the other, the compound can be separated in a single distillation. This is known to be simple distillation, this technique can purify liquids with small amounts of impurities or the boiling point of the components varies from 75-100 C and the apparatus consists of a flask, condenser, distilling head. However, given a compound that has its components less than the minimum temperature for simple distillation to be carried. Fractional distillation is used instead, for the technique is said to be the effect of simple distillations. The apparatus needed are the same with simple distillation, however it consists of a fractionating column that is placed in between the flask and the distilling head.

The objectives for this experiment are to separate and calculate the alcohol

    A distillation experiment was performed in attempt to separate two miscible fluids.This experiment used fractional distillation to separate ethanol from the azeotropic mixture of ethanol and water. The initial composition of the solution did not matter because the goal of the experiment was to distill the ethanol-water solution and obtain 95% ethanol in the distilled fraction. The percentage composition is obtained by the calculated density of distilled product. The azeotropicmixture was separated using a fractional distillation apparatus. The apparatus contained a fractional distillation column with acopper sponge; this was used to capture the water vapor to repeat the simple distillation process, this method yield 88% of ethanol. This form of distillation was shown to be effective in distilling a mixture with similar boiling points.…

    Conclusion: During this lab I learn how to do simple and fractional distillation. Although the group I worked with only did simple distillation, I carefully observed how the group that did the fractional distillation. We collected all the results, to have a more precise range on what the results were. One way to produce an error in this process would have been if our procedures were done wrong or reversed or if we placed the compounds in a improper…

    The data gathered and calculated in the experiment accurately portrayed the way the reactions would have taken place. The chloride analysis was a little bit off from other groups due to the fact that our AgCl was in clumps, creating less surface area, thus our product took longer to burn and may not have burned correctly compared to other groups; yet there are several experimental factors that could have caused us to have different results than other groups, i.e. different measurements for samples. Our sources of error could have included eye measurement error, timing of set solutions error, measurement errors, and small calculation errors. Among other variables, the calibration of the analytical balance and spectrophotometer could have been off slightly, yet our results, like most other groups, still followed the general trend line generated by the graph using Beer’s Law. The measurement errors could have occurred due to the fact that one partner’s perspective of a measurement could be different than the others, but the lab cannot be preformed solo. When it comes to improving the lab, there aren’t to many ways to ensure accurate measurements due to the fact that in any experiment there are human and environment variables that cannot be accounted for, or even prepared for. In any experiment there will always be human error.…

    The distillation procedure is initiated by gradually heating the mixture until it reaches the temperature of the liquid with the lower boiling point. This liquid then turns into a vapor and leaves to mixture and is collected by the set up apparatus. In fractional distillation a vigreux column is used. This provides for surface area for condensation to occur. At each condensation event the vapor is enriched in the low boiling point component and the liquid is enriched in the high boiling point component. The surfaces where condensation occurs are called theoretical plates. Separation is more efficient when there are more theoretical plates. Therefore, fractional distillation is more efficient in separating than simple distillation. Another new technique was gas chromatography. Gas chromatography is used to separate volatile components of a mixture. First, a small amount is draw up into a syringe and the contents of the syringe are placed into a hot injector pot of the gas chromatograph. The components of the mixture evaporate into the gas phase inside the injector. A carrier gas flows through the injected and pushed the…

    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…
