Distillation

DISTILLATION HISTORY • Distilling was used as early as 3500 BC in Mesopotamia where perfume makers had developed it as a technique for isolating the scented oils of flowers and plants, what we know as “attar”. • Around 1100 AD wine was first distilled to make spirit by Irish monks who travelled around Europe. • The results of distillation were considered to have magical powers and this led to alcohol being called “water of life” or “usige beatha” in Gaelic, “eau de vie” in French...

Distillation of vodka

Distillation of vodka Athena Bianca Mattus*, Rency Mae Silvestre, Maria Robelaine Tenefrancia, Shaira Mae Yu Department of Chemistry, College of Science *Corresponding author; e-mail: tinabianca_09@yahoo.com Abstract Through simple distillation, the percent ethanol and percent loss of 15 mL of vodka was computed. The calculations were supported by a flammability test. With the distillation process reaching 100oC, 6.0 mL of distillate was collected. The determination of ethanol from the distillate...

Fractional Distillations

Report Simple and Fractional Distillation Unknown # 2 Purpose In this experiment we aim to demonstrate that we can separate two volatile compounds from a mixture due to the different chemical properties of each compound. We will accomplish this by a separation procedure known as distillation, which relies on each compound having a distinct and separate boiling point. Our pure products will be analyzed with gas chromatography to determine the success of the distillation. Procedures The experiment...

Simple Distillation

Name of the Experiment: Simple Distillation (Semimicroscale Procedure.) Abstract: Distillation is a method of process of separating 1:1 mixture based on differences in their volatilities in a boiling liquid mixture. Distillation is done with the use of simple distillation apparatus shown in Figure 1. In this experiment, simple distillation process was used to determine the identities of the unknown compounds in the solution through the obtained boiling points. The list of probable unknown volatile...

Principles of Distillation

Principles of Distillation What is distillation? Simply, distillation is the process in which a liquid is vaporized (turned to steam), recondensed (turned back into a liquid) and collected in a container. Nature uses a form of distillation to turn salt water (seawater) into fresh water (rain). Why do you use distillation to recycle waste solvents? Solvent-based waste contains volatile material (solvents) and non-volatile material (contaminants like paint, ink, grease, fiberglass, etc.). Many of the...

Fractional Distillation

Fractional Distillation of an Ethanol- water Mixture Abstract The purpose of this experiment is to understand the process of distilling a solution. Thesolution of 50/50 ethanol-water was used in the experiment. Using fractional distillationapparatus ethanol-water mixture was separated. The fractional use of copper sponge wasused in distillation process which created the heat exchange area between the vapor of ethanol and liquid water. The fractional distillation process yield 9.5 ml of ethanol...

Steam Distillation

purpose of this experiment was to isolate the aromatic hydroxyl compound, eugenol from crushed cloves using steam distillation. After conducting the distillation, the expected two layers were not visible in the centrifuge tube. Subsequently, the extraction and evaporation did not produce the expected oil. This result is probably due to the collection of only water vapor during distillation. From another group’s data, 3.80% of the oil was recovered from the cloves in which the major component is eugenol...

Fractional Distillation

purpose of this experiment is to form a yeast mixture with water, organic compound like sucrose, Ba (OH) 2 for fermentation process, and use simple distillation method to purification from the fermentation mixture. Abstract and Theory: There are many techniques that are used to purify liquid. The one that is going to use for this lab is simple distillation. It is a process of which separating a mixture based on the tendency of the mixture to vaporize into a boiling liquid. For this particular experiment...

Steam Distillation

Cheryl Baclit Chem 234 Experiment 4: Steam Distillation Introduction The purpose of this experiment is to extract Eugenol from Cloves using steam distillation as a purification technique and to transfer Eugenol from the aqueous phase to the MeCl2 phase. With steam distillation, the boiling point of a mixture of immiscible liquids is lower than the boiling points of the individual components. Water from the steam is one of the components of an immiscible liquid mixture. The vapor pressures of...

Steam Distillation

eugenol in the basic aqueous layer, and acetyleugenol in the organic layer. The basic aqueous layer can be acidified to re-extract eugenol from it. And the organic layer can be dried and concentrated to yield acetyleugenol The principle of steam distillation is based on the fact that two immiscible liquids will boil at a lower temperature than the boiling points of either pure component, because the total vapor pressure of the heterogeneous mixture is simply the sum of the vapor pressures of the individual...
