Edward Cross Organic Chemistry December 10‚ 2012 Title Steam Distillation of Cloves and Extraction of Eugenol Authors Edward J. Cross* Summary The isolation of Eugenol from Cloves begins with whole cloves and then using a steam distillation apparatus to obtain the cloves oil substance. Then with the mixtures of water and dichloromethane to form two immiscible layers. The layers were dichloromethane substance and aqueous The entire substances that are separated into two individual

Erlenmeyer flask and a Buchner funnel. This will be done by selecting from the Equipment section on the toolbar and selecting Erlenmeyer Flask-250mL. Next‚ right click on the flask and select Buchner Funnel. Right click on the beaker and select Pour/Decant. Move the beaker above the funnel and you will see a white area at the bottom of the flask. 4. Lastly‚ you will need to record the weight of the precipitate. Right click on the flask and select Buchner Funnel. A message will appear asking

Separation of a Mixture Introduction: Mixtures are not unique to chemistry; you use and consume them on a daily basis. The beverages you drink each morning‚ the fuel you use in your automobile‚ and the ground you walk on are mixtures. Very few materials that you encounter are pure. Any material made up of two or more substances that are not chemically combined is a mixture. The isolation of pure components of a mixture requires the separation of one component from another.

Gravimetric Analysis of SULFATE as Barium Sulfate. Objectives * To learn the techniques associated with gravimetric analysis. * To use stoichiometry to calculate the percentage by mass of sulfate in an unknown sulfate salt. Background Gravimetric analysis is a quantitative method for accurately determining the amount of a substance by selective precipitation of the substance from an aqueous solution. The precipitate is separated from the remaining aqueous solution by filtration and

perspective on redemption. The author (2007) explains that in Scripture describes a redemptive funnel‚ that depicts redemption. According to McMinn (2007)‚ near the beginning of the Old Testament‚ it defines redemption as an all-purpose concept‚ but by the end of the New Testament‚ it has turn out to be rather specific and focused (p 296). McMinn (2007) explains the redemptive funnel concept. The redemptive funnel contains two type of act of redemption‚ which are general acts of redemption and specific

tea bags were used in the experiment; tea leaves were weighed having 8.5333 grams. The leaves were boiled in a beaker with 150ml of water; the aqueous tea extract was transferred in a seperatory funnel mixed with DCM (20ml)‚ done thrice. The DCM layer was washed with 20ml 6M NaOH in the seperatory funnel; the organic layer was dried with anhydrous Na2SO4. The dried organic layer turned into crude caffeine was purified in a sublimation set-up. A capillary tube was used to insert the pure caffeine

Extraction of Caffeine from Tea Leaves Jaybee Balilea‚ Sharmaine Baysic‚ and Maria Anjelette Patricia Belen 3BIO7‚ Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Extraction is a technique for isolating and purifying organic substances. In this technique‚ a solution is combined thoroughly with a second solvent that is immiscible with the first solvent. The solute is extracted from one solvent into the other because it is more soluble in the second solvent

The percent yield was 70 percent. Separation of the crude product was conducted by extraction using a separatory funnel‚ and drying was done by using sodium carbonate. The purification was conducted using distillation. Since esterification reactions are slow‚ they need a catalyst like inorganic acids. The reactants need to be refluxed in order to increase the yield

added to the flask containing the crystals and. the accumulation of the crystals was broken down with a stirring rod. The crystals were collected by using a Bucher funnel with a filter paper‚ a rubber adaptor and a filter flask connected to a vacuum. Crystals were washed out of the flask with the filtrate and rinsed off on the funnel with 10 ml of methanol. Crystals were then spread on a paper towel to completely dry. Product was weighted and the percentage recovery of (-) amine(+) hydrogen tartrate
