Orgo Procedure

Submitted by hamacdonald on Fri, 11/17/2017 - 14:40

      In a 250 mL round bottom flask, nutmeg (1.010 g, 2.29 mmol) and tert-butyl methyl ether (3 mL) were added and boiled for ten minutes. Once the solution had boiled and cooled, the liquid layer was filtered into a 25- mL Erlenmeyer flask via microscale filtration techniques. Tert-butyl methyl ether (2 mL, 22.69) was added to the round bottom flask, heated, and filtered again (percent recovery, 24.578- 24.107). After the second filtration, the 25- mL Erlenmeyer flask was warmed and air was blown over the solution until all of the solvent evaporated and the solid yellow product remained. The product was dried for five minutes and the crude weight was obtained (0.471 g, 0.65 mmol) and acetone (9.4 mL) was added and warmed until the solid dissolved. The solution was cooled to room temperature for 5 minutes and then cooled in an ice bath for 15 minutes. The solid product was filtered via suction filtration and washed with cold acetone. After filtration and drying the crystals were collected, weighed (0.189 g, 0.261 mmol) and the melting point range (49-51 °C) of the product was obtained.

Very concise and well-written! I'd just say be careful about how you report the number of minutes, because sometimes you write them out (like "ten minutes" in the first sentence), and sometimes you leave them as numbers (like "5 minutes,15 minutes" later on). 

I also agree that this is concise and easy to follow; however, I think there are some steps missing (I also did this orgo lab report). In addition, you discuss some of your results in your methods section, which is unusual.
