    through reflux, vacuum filtration and recrystallization techniques. The melting point was recorded to ensure the completion of this reaction. The melting point was determined to be 69℃. The limiting reagent for this reaction was determined to be benzoin. Using the theoretical yield of 5.89 g the percent yield was calculated to be 70.97%. While special care was taken to follow the procedure, the recrystallization of the crude benzil product was challenging because while scratching the flask with…

    apparatus included 250mL distillation flask, a 100ml receiving flask, a condenser for water to run through, and a thermometer to monitor the temperature. The measurements of the empty flasks were 37.5120g for the distillation flask and 31.1978g for the receiving flask. The mass of the unknown liquid mixture was determined by transferring the mixture into the distillation flask and subtracting the initial…

    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 flask was capped and the two liquid were mixed in a thorough manner. Ventilation was required after every…

    For the first synthesis reaction, camphene was converted to isobornyl acetate. In the fume hood, a sample of 1.36 g of camphene was added to a 25-mL round-bottomed flask along with a stir bar. To dissolve the camphene, 3.0 mL of glacial acetic acid was added into the flask. The flask was fastened onto a ring stand and immersed in a water bath that was on top of a stir plate. A thermometer wire was placed in the water bath to monitor the temperature throughout the experiment. After the camphene…

    funnel. 3. Open the stopcock on the separatory funnel and draw off the lower aqueous portion of the liquid into a 125 ml Erlenmeyer flask. 4. Since some of the aqueous solution is still dissolved in the ethyl ether, add an additional 20 ml portion of 5% NaHCO3 and repeat the extraction procedure. Combine this second aqueous portion with the first 5. Place the 125 ml flask into a warm water bath (60 C) and gently heat. This will evaporate any ether still present in the aqueous portion. Do not…

    vigorously, to combat oxidation and pulverize the by-product magnesium sulfate, in a 250 mL round bottom flask for 5 to 10 minutes, then fit with reflux apparatus – including 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…

    used later in order to conduct the heated reflux for reaction. A boiling flask was obtained and into it went 0.01mol (1.521 g) of methyl salicylate and 15 mL of 6M sodium hydroxide including 3 or 4 boiling chips. The reaction was refluxed and heated from 30 minutes. After the reaction was successfully conducted, the flask was observed evidence of cloudiness (or and oil layer) and the lingering of a wintergreen smell. Once the flask was proven to not have cloudiness etc., the condenser was…

    30 g thiamine hydrochloride to a 25-mL Erlenmeyer flask. Dissolved the solid in 0.45 mL of water by swirling the flask. Add 3.0 mL of 95% ethanol and swirl the solution until it is homogeneous. To this solution it was added 0.90 mL of an aqueous sodium hydroxide solution and then it was swirled in the flask until the bright yellow color faded to a pale yellow. Students then swirled the contents of the flask until it was homogeneous. Stopped the flask and was let to stand in a dark place for 2…
