Separatory funnel

The separatory funnel was used to separate glucose, ethyl cinnamate, and cinnamic acid. The purity of ethyl cinnamate and glucose were tested through IR spectroscopy, and the purity of cinnamic acid was tested by finding the melting point. Experimental Methods 0.604 grams the starting mixture of cinnamic acid, ethyl cinnamate, and glucose was weighed out then was placed into a separatory funnel. Diethyl ether (10 mL, 0.134916 mol) was then swirled…

separate the essential oils from the cloves (Setzer, W., 2008). The distillate was poured into a separatory funnel and extracted three times with dichloromethane to extract the water. After being extracted three times, a fifth of the solution was set aside to be later used in the thin-layer chromatography plate (Setzer, W., 2008). The remaining four-fifths were put back into the separatory funnel to be extracted three times with 5% NaOH in order to deprotonate the solution, which converts it…

(for diethyl ether evaporates quickly) and sat for a few minutes. During this time, a simple distillation apparatus was set up. A 50-mL flask was pre-weighed at 55.27 g. The oil and solvent mixture was filtered into the flask using filter paper and a funnel. It was then placed in a hot bath to distill off the diethyl ether until only cinnamaldehyde remained. When the distillation was finished, the diethyl ether was disposed of while the flask containing the oil cooled down. When it was cooled,…

Aims of Experiment 1. To extract benzoic acid from the toluene-benzoic acid mixture, using oxidation-reduction reaction (chemical properties) and difference of solubility (physical properties) –Expt. 1 2. To learn how to recrystallize the solid organic compounds well for getting more purified compounds –Expt. 2 3. To find which differences between raw product and recrystallized product are observed. –Expt. 2 4. To determine melting point range of organic compounds with digital melting point…

ice bath, and then the extraction apparatus was constructed. Once the microwave was done, the vessel was rinsed with 5mL of water, which was poured into the separatory funnel. Then cold sodium hydroxide was then added portion wise to the separatory funnel and the funnel was swirled. Next, 10mL of dichloromethane was added to the separatory funnel, which was then inverted and vented toward the back of the fume hood. Once mixing was complete, the organic layer was separated into…

First, 1.32 g of isoborneol was mixed with 1.00 mL of glacial acetic acid. The solution was heated to 50° C while 1.70 mL of NaOCl added. Then 15.0 mL of NaOCl was measured into a separatory funnel and added dropwise to the solution for 10 minutes. The flask was sealed while heating and stirring continued. NaOCl in the solution was tested every five minutes using starch-iodide paper for 30 minutes. After 10 minutes, 2.0 mL of NaOCl was added. A total of 6.0 mL of NaOCl was added over a 20 minute…

agent), sodium bicarbonate, acetic acid, and acetone.3,6 To begin the experiment 9-fluorenol, acetone, acetic acid, and sodium hypochlorite were added in sulfate is added to remove excess water from the hexane layer that is collected using the separatory funnel.6 To determine the success of the experiment, percent yield was used to determine how much product was recovered, and Thin Layer Chromatography was used throughout the experiment to monitor the reaction process.6 The…

The reaction mixture was then placed in 15.618 g of ice in a 50-mL Erlenmeyer flask and solidified in the ice bath for twelve minutes. A vacuum filtration apparatus was constructed using a 150-mL filter flask and a Büchner funnel. The newly formed solid was poured into the funnel and rinsed with cold deionized water. Filtration began and lasted for fifteen minutes. The melting point and mass of the collected sample were measured, and a small amount of this solid sample was placed onto a Thermo…

experiment was not 100% percent due to certain factors in the natural process of synthesis and the technical failures within the experiment. Because of this, future researchers are advised to add smaller amounts of NaHCO3 to avoid clogging of the separatory funnel. Also the product must be fully stratified, with only the organic and aqueous layer visible, before separation of these. In addition, all of the procedures should be followed to facilitate a smooth flow of the experiment and the…

removed from impurities, and washing is the process by which unwanted products or impurities are selectively removed from the desired product. In liquid-liquid extraction, unknown B was dissolved sequentially into two immiscible liquids via a separatory funnel. The differences in solubility of the liquid solvents was important because it allowed 1,4-dimethoxybenzene and neutral benzoic acid to eventually separate or extract…
