Diethyl ether

Procedure: Out of three substances, benzoic acid, ethyl-4-aminobenzoate, and acetanilide, two of them were randomly given out, weighing 75 mg each. These mysterious substances were both placed in a 25-mL flask with 6 mL of diethyl ether. The substances with the diethyl ether were mixed together until the solids dissolved. The solution was cooled in an ice bath for a couple of minutes. Once the solution was cooled, 3 mL of 3M HCl was added and swirled into the solution. The top of the 25-mL…

case diethyl ether, as a means of separation. Utilizing this technique, of the original 3.8146 grams of nutmeg, 0.1905 grams of trimyristin were recovered, yielding a 4.99 % composition. This methodology can be used to extract oils for use in medicine, and is used commonly to brew coffee or tea. Solid-liquid extraction utilizes differences in solubility of parts within a mixture to isolate a particular component. Solubility of a compound is based on the…

CaCl2 Drying Tube, 125 mL Dropping funnel, Claisen adapter, and thermometer adapter – and add anhydrous ethyl ether (40mL) through the dropping funnel. Bromobenzene (3mL) and Anhydrous Ethyl Ether (15mL) was added to the reaction flask through the dropping funnel dropwise and in halves. Reflux the reaction chamber for 30 minutes over a steam bath. Benzophenone (9.1g) was dissolved in Diethyl Ether (100mL) and added to the reaction chamber and reflux was initiated again for 15 minutes. The…

be identified with ease. Clearly, it was observed that the residue comprised a combination of sodium bicarbonate extracts once the ether had evaporated from the hood. How to Remove Water that was dissolved in Diethyl Ether Water that was dissolved in diethyl ether can be removed using a commercial drying agent such as MgSO4 salt. The salt dehydrates diethyl ether thus removing all the water. Why Several Small Extractions are Preferred to One Large Extraction Evidently, performing several…

their melting points and the percent recovered was calculated. First, the sucrose was separated by dissolving the organic acid and the organic neutral compound in diethyl ether. 104.9% was recovered, so that means the sucrose was not entirely pure. The sucrose could have been contaminated by another compound or residual diethyl ether may not have evaporated from the very bottom of the tube. To only dissolve the sucrose water could be added. Neither the carboxylic acid nor the neutral…

forming N,N-diethyl-m-toluamide. One interesting note is that after the addition of thionyl chloride and pyridine to m-toluic acid, an evolution of gases was observed along with a color change inside the reaction mixture. The…

with hydrochloric acid, which led to a significant shift in the polarity of the said compound, although the conjugate acid of benzocaine formed as a result. Due to the change in polarity, the state of benzocaine shifted from being solubilized in diethyl ether to water. Through vacuum filtration, water was removed. Sodium hydroxide was added to the separated water in order to produce…

solvents into each other. In this experiment, three organic compounds (aspirin and naphthalene) will be separated from each other. The two compounds are all soluble in ethyl ether (an organic solvent). By selectively reacting each organic compound, we can make it soluble in water and insoluble in ethyl ether. Since ethyl ether and water are insoluble in each other, they will form two phases and can be separated from each other using a separatory funnel. The reacted organic compound…

reaction temperature is elevated to room temperature. The reaction mixture stirred for 2 days. The precipitated dicyclohexylurea was separated by filtration. The mixture was concentrated by rotary evaporator and then, was precipitated into additional diethyl ether twice to remove the unreacted…
