Resolução do ibuprofeno: um projeto para disciplina de química orgânica experimental

Abstract: Recebido em 29/2/12; aceito em 3/4/12; publicado na web em 2/7/12 RESOLUTION OF IBUPROFEN: A PROJECT FOR AN EXPERIMENTAL ORGANIC CHEMISTRY COURSE. A practical and didactic sequence of experiments was proposed to illustrate the stereochemistry concept, optically active compounds, resolution of racemates, and use of the NMR technique, including 2D-COSY for identification of organic compounds, on a laboratory course for undergraduate students. The sequence was: extractions of racemic ibuprofen and chiral naproxen… Show more

“… 46 and 47 ) and TPSSH 48 methods with the 6-31G(d, p) base set 49 in order to evaluate the ibuprofen experimental infrared spectra data and predict the best model that describes the structure. The error calculation was obtained from the sum of theoretical wavelengths minus the sum of the experimental wavelength divided by the sum of experimental wavelengths, 50 according to eqn (5) . …”
