Performing this experiment, we used the technique called Acid-Base extraction to isolate Eugenol, which is one of the main ingredients of clove oil. Acid-Base extraction is the most efficient method for isolating organic component; it is efficient because it purifies the acid and base mixture based on their chemical identities. We have seen throughout this experiment that acid and base play an important role, when it comes to solubility in water. Our basic knowledge of acid and base is acid is a proton donor and base is a proton acceptor. This ideology helps us to understand why organic compounds are not soluble in water. When compounds tend to be insoluble, we have to use acid and base reaction, to change its solubility. The changes that occurred in this experiment is when an organic and inorganic solvents mixes. This results in a polar substance, which tends to be soluble in water, however in certain cases it may be non-polar, thus it won’t be soluble in water.
We learned from lab lecture that Clove Oil is made up of 85% Eugenol, 10% Acetyl Eugenol, and 5% Beta Caryophyllene. Starting this experiment, we knew that the extraction was going to form varies layers due to the density differences. When placing three different substances, we saw that two layers formed because the Clove Oil is soluble in MTBE, but not in water. In order, to get the organic layer we used separatory funnel to take out the excess substances and leave the oil layer. Then we transferred to a beaker and dried with Magnesium Sulfate. Lastly, we filtered the liquid using funnel; we placed the liquid to boil, let it cool to room temperature. The purpose of drying and evaporation is to help us with the Gas Chromatography analysis of the product.

... peak between 125-200 second. This increased may have occurred due to not having enough amount of Beta-Caryophyllene to be read in the sample. Overall, this experiment was similar to the accepted values, expect for the minor errors that may have occurred.
Conclusion
Indeed, I accomplished my objectives in this experiment of isolating the components in clove oil, Eugenol, and Beta-Caryophyllene. I thoroughly liked this experiment because I learned the techniques to extract and obtain products. Also, helped me to understand why chemical properties are important in solubility. This is relatable to what I learned in class about solubility properties, doing this experiment hands-on taught me the concept of density and solubility. Additionally, understanding this concept portrayed how compounds and solvents behave when mixed together, which was the purpose of this lab.

Preparation A Acid Base Extraction Technique For Separate Organic Compounds Successfully By Separatory Funnel Preforming On Two Liquids

- The Objective The purpose of this experiment was to learn and preform an acid-base extraction technique to separate organic compounds successfully and obtaining amounts of each component in the mixture. In this experiment, the separation will be done by separatory funnel preforming on two liquids that are immiscible from two layers when added together. The individual components of Phensuprin (Acetylsalicylic acid, Acetanilide, and Sucrose as a filler) was separated based upon their solubility and reactivity, and the amount of each component in the mixture was obtained....   [tags: Solvent, Sodium bicarbonate, Hydrochloric acid]

The Extraction Procedure For Separate The Acid, Base And Neutral Components Of The Solution Into Separate Phases

- The extraction procedure was undertaken in order to separate the acid, base and neutral components of the solution into separate phases. This procedure was executed using different solvents with different polarities in order to extract the different solutes. The recrystallization procedure was undertaken in order to purify the solutes further by removing any contaminants. This was done by using hot solvent and then allowing it to cool, which causes the compound to precipitate out. This creates purified crystals that have less other associated compounds....   [tags: Solubility, Solvent, Solution, Acetic acid]

Acid Base Extraction Essay

- Acid Base Extraction The purpose of this laboratory assignment was two-fold, first, we were to demonstrate the extraction of acids and bases, finally, determining what unknowns were present. Second, we were to extract caffeine from tea. These two assignment will be documented in two separate entities. Introduction: Acid/base extraction involves carrying out simple acid/base reactions in order to separate strong organic acids, weak organic acids neutral organic compounds and basic organic substances....   [tags: essays research papers]

Chemical Makeup And Acid Base Reactions Essay

- Exaction is where a solute is transfer from solvent A to solvent B (Ketcha, 47). A possible method to do this is changing the chemical makeup by using acid-base reactions (Ketcha, 42). The acid-base reactions change the solubility of the solute. If the original solute is ionic and is dissolvable is solvent A but not B, then adding the acid HCl would change the solute to its conjugate acid. The resulting acid would then be soluble in B but not A. To revert the change, just add the base NaOH to the solution....   [tags: Solvent, Solubility, Chemistry, Solution]

Our Experiment to Separate a Mixture of Organic Compounds Essay

- ... The inorganic salts favor the aqueous phase, but the organic compounds prefer the nonpolar organic solvent. By using a separatory funnel, two to three extractions of an aqueous-organic mixture is enough to methodically transfer the organic acid (benzoic acid) from the organic solvent (diethyl ether) to the aqueous phase. Initially, the organic carboxylic acid becomes a charged species after it is deprotonated by a base like sodium hydroxide, producing a carboxylic salt. After completing the extraction, an acid, such as hydrochloric acid, is added to the basic aqueous solution causing the sodium carboxylate salt to change back to the default carboxylic acid, which will precipitate out of...   [tags: acid, melting point, reaction]

A Mixture Of Three Substances ( Benzoic Acid Essay

- In this experiment, a mixture of three substances (benzoic acid, 2-naphthol, and 1-4 dimethoxybenzene) will be separated based off acidity strength using the liquid-liquid extraction technique through a separatory funnel. Benzoic acid and 2-napthol will be converted into ionic salts when reacting with their appropriate bases (sodium bicarbonate and sodium hydroxide). Both ionic salts will then form solids through the addition of acidic HCl. Neutral 1,4 – dimethoxybenzene forms a solid through the evaporation of ether....   [tags: Acid, Water, Sodium chloride, Chemistry]

Use Of Extraction And Crystallization Of A Centrifuge Tube Essay

- In order to separate the mixture of fluorene, o-toluic acid, and 1, 4-dibromobenzene, the previously learned techniques of extraction and crystallization are needed to perform the experiment. First, 10.0 mL of diethyl ether would be added to the mixture in a centrifuge tube (1) and shaken until the mixture completely dissolved (2). Diethyl ether is the best solvent for dissolving the mixture, because though it is a polar molecule, its ethyl groups make it a nonpolar solvent. The compounds, fluorene and 1, 4-dibromobenzene, are also nonpolar; therefore, it would be easier for it to be dissolved in this organic solvent....   [tags: Solvent, Ethanol, Solubility, Sodium chloride]

Acid And Benzoic Acid Essay

- In this experiment, the goal is to separate naphthalene and benzoic acid from one gram of a crude mixture containing them both, using extraction. A general requirement of a solvent in extraction is solvating one of the pure compounds in solution but not the other. Position in the separatory funnel is determined by density of each layer. The denser layer will be on the bottom of the separatory funnel while the less dense layer will be the top layer of the separatory funnel. For extraction to be used as an effective method for separation, the components of a mixture that need to be recovered must not be soluble in the same solvent....   [tags: Solvent, Solubility, Chemistry, Benzene]
