This lab explored techniques in steam-distillation to extract clove oil from ground cloves. In the second part of the experiment, designed by the students, eugenol was isolated from clove oil via chemically active extraction, using acid-base chemistry. This isolated compound was analyzed via Infrared Spectroscopy and Gas Chromatography.
Eugenol, eugenol acetate and caryophyllene (Figure 1) were isolated from ground cloves via steam distillation. To do this, 5.04g of ground cloves were added to a 500mL round bottom flask with 40mL of dH2O, boiling stones and 3 drops of an antifoaming agent (to prevent violent boiling). The contents of the flask were heated using a heating mantle for 75 minutes. The distillate was condensed through a water jacket …show more content…
To accomplish this, a series of chemical extractions were performed. First, 15mL of hexane were added to the clove oil (in the vial, to ensure that all oil was obtained), creating a large volume organic layer, and this solution was transferred to a 125mL seperatory funnel. Then 25mL of 5% NaOH was added to the funnel, and the funnel was shaken with venting. This yielded an aqueous layer and an organic layer. The aqueous layer contained the eugenol, while the eugenol acetate and caryophellene remained in the organic layer. Eugenol is weakly acidic because it is a phenolic compound, whereas eugenol acetate and caryophellene are neutral compounds. The addition of NaOH allows for a chemically active extraction, which allows for the selective formation of the eugenol salt, but not a reaction with the neutral compounds. The eugenol will react with the NaOH, resulting in the formation of a sodium salt of eugenol that is soluble in the aqueous layer. The neutral compounds do not react with NaOH, and remain in the organic layer. The aqueous layer was then drained, and set aside. The remaining organic layer was washed again with 25mL of 5% NaOH to ensure complete extraction of eugenol, and the aqueous layer was drained and added to the first aqueous layer. The organic layer was discarded. The aqueous layer was cooled on ice (to prevent dangerous levels of heat evolution when …show more content…
The organic layer was drained and set aside, and then 15mL of hexane were added to the remaining aqueous layer, and the extraction was repeated to ensure the complete extraction of eugenol. This organic layer was drained into the first organic layer. The organic solution was dried with anhydrous sodium sulfate, and this mixture was filtered by gravity filtration to yield a water-free organic solution in a 150mL round bottom flask. This hexane solvent was evaporated via rotary evaporation, leaving the eugenol oil behind in the flask. A sample of this oil was prepared in dichloromethane so that it could be analyzed by gas chromatography, and the rest of the oil was saved for IR

...Taylor Small 09-23-13 Lab Report: Determination of Alcohol Content Blame it on the Alcohol Objective: Boiling is a process familiar to anyone who has cooked pasta or brewed tea. As heat is applied to a pan of water, the temperature of the water increases until it reaches 100°C (212°F). At this temperature, additional heat causes the water to bubble vigorously as the liquid water is converted into gaseous water, or steam. Most organic liquids will behave in a similar fashion. On heating, the temperature of the liquid increases until the boiling point is reached. Additional heating causes the liquid to vaporize accompanied by vigorous bubbling of the liquid. The boiling point of a substance is a physical property of a substance and can be useful for characterizing that substance. The fact that different substances have different boiling points allows us to separate them. The process of heating a substance until it is vaporized, cooling the vapors, and collecting the condensed liquid is the basis of a commonly used purification technique called distillation. Method: The fractional distillation apparatus was set-up as shown in the illustration and was approved by the TA. 50 mL of wine was added into the flask along with boiling chips and the flask was then placed into the heating mantel. A flow of cold water was set-up to continuously run through the condenser and the variac box was set to 5. The temperature at the distilling head was measured and recorded for every mL...

When any student is unable to understand a particular topic, he is advised to imagine the whole matter and then try to understand it. Normally, this method succeeds. But in engineering stream considering the study of wide range of process and equipments involved in it, it is hard to understand the unit operations and processes just through books or even with imagination .Unless one happens to see the process, equipments, he is like a soldier who knows to fire the gun ,but is yet to face a war. Industrial training is one of the most vital part of a syllabus of chemical engineering, which not only teaches one the industrial unit operations, equipments and other technical aspects, but also teaches discipline, interaction with various people irrespective of their posts, the importance of teamwork, etc. This report contains a brief introduction to GUJRAT REFINERY and knowledge gathered about various units in refinery during the training.

...successfully completed my Semiar-1 project report on the topic ‘Distillation Process’. I would also show my gratitude towards my Programme Leader Dr. Monika Thakur and our HOD Dr Amarinder Singh Bawa for including such a project in my course curriculum which gave me a chance to gain knowledge as much as I can in this field. Thank you Varun Gadodia BTech Food Technology IV semester Amity Institute of Food Technology Introduction This report examines the distillation process. This will enable the reader to understand the necessary components along with distillation calculations. Distillation is a process that separates two or more components into an overhead distillate and bottoms. The bottoms product is almost exclusively liquid, while the distillate may be liquid or a vapour or both. The separation process requires three things. First, a second phase must be formed so that both liquid and vapour phases are present and can contact each other on each stage within a separation column. Secondly, the components have different volatilities so that they will partition between the two phases to different extent. Lastly, the two phases can be separated by gravity or other mechanical means. Distillation differs from absorption and stripping in that the second phase is created by thermal means. The report also high lights the important equipments/methods...

...Pentachlorophenol (PCP) in wood treatment 1.Introduction Wood is a hard, fibrous structural tissue found in the stems and roots of trees and other woody plants. It has been used for thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also mediates the transfer of water and nutrients to the leaves and other growing tissues. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. The Earth contains about one trillion tonnes of wood, which grows at a rate of 10 billion tonnes per year. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy. In 1991, approximately 3.5 billion cubic meters of wood were harvested. Dominant uses were for furniture and building construction. The wood-preserving industry treats lumber with various chemicals to protect against insect damage and decay. Chemically preserved wood is used in products for outdoor use such as railway ties...
