1. What can you conclude if your dry aspirin sample has a lower melting point than the literature value? 2. If the yield of your dry aspirin is greater than 100%, what must you do experimentally to obtain a more reasonable yield? 3. Would the product isolated after Part A. 3 have a higher or lower melting point than that isolated after Part A. 5? 4.

Briefly explain how you determined when the reaction was complete PROCEDURETo a six inch test tube was added thiamine hydrochloride (0.65 g), followed by water (2mL). The mixture was gently shaken until homogeneous, and then ethanol (7.5 mL)was added. Finally, sodium hydroxide (10%, 1.5 mL) was added and the mixture wasgently stirred to ensure complete mixing.Benzaldehyde (3.8 mL) was then added at room temperature in one portion with gentlestirring. The pH of the resulting reaction mixture was determined and adjusted to >10by dropwise addition of 10% sodium hydroxide. The reaction mixture was then partiallysubmerged in a 65 °C water bath2 and the progress of the reaction was periodicallymonitored by TLC analysis.Once TLC analysis indicated that the reaction was complete, the reaction mixture wascooled to approximately room temperature, and then chilled in an ice-water bath. Theresulting precipitate was collected by vacuum filtration and air-dried. The crude productwas purified by…
Calculate the theoretical yield of virstatin ethyl ester and virstatin. Procedure – Step 1 Synthesis of virstatin ethyl ester (with notes and musings about procedural steps in italics) 1,8-naphthalimide (0.25 g) and potassium carbonate (0.26g) are added to a 10 ml round bottom flask containing a stir bar. 1.3 ml DMF (N,N-dimethylformamide) is added to the flask. The DMF will be in a “sure seal” bottle with a septum. You will obtain the DMF using a syringe and needle. Wear gloves when obtaining and dispensing the DMF. Add ethyl 4-bromobutanoate (0.27 ml) (it might say ethyl 4-bromobutyrate on the bottle) to the reaction flask, using an automatic pipet. Heat under reflux, with stirring, for 1 hour. What will the sand temperature have to be to get DMF to boil?? When would you start heating the sand!? After cooling to room temperature add 5 ml water to the reaction solution and cool the resulting mixture in an ice bath. Using a Buchner funnel, vacuum filter the ice cold…
