Abstract

Distillation is a process of converting a liquid to a vapor, and then, collecting the distillate in another container. There are four distillation methods which are fractional distillation, simple distillation, vacuum distillation and steam distillation. The methods used here are fractional and simple distillation because they are the most efficient in distilling vodka.

Introduction

The study is about distillation. Distillation is a process of converting a liquid to a vapor, and then, collecting the distillate in another container. This technique is used to separate components in a liquid mixture which have different boiling points, or to separate a component that is not volatile. It is one of the methods used when purifying liquids. For example, it is used to concentrate alcoholic beverages. The four distillation methods include simple distillation, fractional distillation, vacuum distillation (distillation at a reduced pressure), and steam distillation. The objective of the study is to differentiate simple from fractional distillation, separate the components of the alcohol beverage used, and to calculate the percentage of ethanol in the beverage. Simple and fractional distillation are the methods to be used since it is the most efficient to be used in this experiment. Since the experiment worked only on the two methods, the other two methods will not be studied.

Methodology

The equipment used are the condenser, boiling stones, beaker, thermometer, distilling flask, alcohol lamp, iron stand, wire gauze, iron clamp and test tubes that were calibrated. Vodka is the substance that was distilled. First, the group put up the distillation set up by assembling the instruments,

    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…

    Distillation has been used since antiquity to separate the components of mixtures. This method has been used to manufacture different organic chemicals but the most recent application is the refining of petroleum in order to produce fuels, lubricants and petrochemicals. In this experiments, the separation of 2 distilates were carried out using the differences in boiling points and the data was used for a gas chromatography test.…

    Experiment II involved two kinds of distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component, while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture, which has boiling points of 77º and 125 º, respectively.…

    Background: Distillation consists of heating a liquid until it vaporizes, and then condensing the vapor and collecting it in a separate container. Distillation is used to separate mixtures of liquids that either have different boiling points, or that have one component that does not distill. There are many types of distillation, each of which has a distinct purpose. Steam distillation is used to isolate volatile substances that have high boiling points. When two immiscible liquids are distilled together, the amounts of each component in the distillate are constant. Also, the boiling point of the mixture is lower than that of either of the individual components. This is because the components do not have compatible intermolecular forces, and so the component in lesser concentration will form “bubbles”, like oil droplets in water, weakening the overall intermolecular forces in the mixture, and thus lowering the boiling point. This process allows high- boiling compounds, which can decompose before they boil if heated alone, to be distilled at temperatures below 100°C. Once the liquid mixture is heated to its boiling point, the liquid is converted to vapor. The vapors, richer in a more volatile component, are then condensed into a separate container.…

    Based on the theoretical and actual refractive index of both simple and fractional distillation we can determine the success of the experiment. The results are also supported by general conditions of distillation. The actual refractive index for the simple distillation was very similar to the theoretical index we calculated.(Simple- 1.3903 at 22.1 degrees versus Fractional 1.3707 at 22.9) The theoretical refractive index was 1.397 at 20.5 degrees. If depicted in graph form, the lines would match up more closely than the refractive qualities in the fractional distillation. Simple distillations are best separated with two compounds whose boiling points have a difference greater than 30 degrees celsius. The difference between cyclohexane and 2-methylpentane is 52.74 degrees.(cyclohexane-80.74-2 methypentane-28).…

    In fractional distillation, the liquid mixtures being separated are soluble in each other and boil at less than 25 0C from each other at 1 atmosphere. Each component is called a fraction. As the mixture is heated, it boils, and the vapor that comes off this liquid is richer in the lower boiling component. The composition of the liquid still in the flask has changed a little?it is richer in the higher boiling component. As more of this liquid boils, hotter vapor comes up, mixes with the first fraction, and produces a new vapor. This vapor is richer in the lower boiling component. In a nutshell, fractional distillation is revaporizing the condensate. Simple distillation is only one cycle of the vaporization/condensation.…

    Since simple distillation is a physical process, it separated the two chemicals from the mixture based on how easily they vaporize. As the mixture was heated, the temperature rose until it reached the temperature of the lowest boiling substance in the mixture which was cyclohexane. The temperature at which the first drop was collected was 79.5oC and the distillation of cyclohexane was stopped when the still-head temperature was 94.5oC . Therefore, the boiling range of cyclohexane in this experiment was 79.5oC- 94.5oC.The resultant hot vapor passed through into the condenser and was converted into liquid, which was then collected into a graduated cylinder. During this time, the ethyl benzene remained in its original phase. Since cyclohexane had a lower boiling point, it is considered to be more volatile in comparison to ethyl benzene. After a plateau in temperature was observed, the temperature was increased in order for ethyl benzene to reach its boiling point. The temperature at which ethyl benzene was collected was 127oC and the distillation of ethyl benzene was stopped when the still-head temperature was 138.5oC. The boiling range for ethyl benzene was observed to be in between 127oC-138.5oC. The liquids were collected in increments of 4mL. The first 28mL collected were of cyclohexane and the last 16 mL collected were of ethyl benzene,…
