In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system., Quality Control of 3-Nitrophthalimide
To a solution of potassium hydroxide (16.1 g, 286 mmol) in water (500 mL), was added 3-nitrophthalimide (25.0 g, 130 mmol) in portion at 0 C. The suspension was stirred at 0 C for 3 hrs, and then heated to 30 C for 3 hrs. To the solution, was added HC1 (100 mL, 6N). The resulting suspension was cooled to 0 C for 1 hr. The suspension was filtered and washed with cold water (2 x 10 mL) to give 3- nitro-phthalamic acid as a white solid (24.6 g, 90% yield): ?H NMR (DMSO-d6) 5 7.69 (brs, 1H, NHJ]), 7.74 (t, J= 8 Hz, 1H, Ar), 7.92 (dd, J= 1, 8 Hz, 1H, Ar), 8.13 (dd, J= 1, 8Hz, 1H, Ar), 8.15 (brs, 1H, NHJ]), 13.59 (s, 1H, 01]); ?3C NIVIR (DMSO-d6) 5125.33, 129.15, 130.25, 132.54, 136.72, 147.03, 165.90, 167.31.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 603-62-3.
