Google Scholar. Chem. Sci. 6/28/11 Chirality, Gas Chromatography and Menthone Abstract The purpose of this experiment is to isomerize (-)-menthone to its diasteriomer (-)-isomenthone under acidic conditions. Isomerizations among individual isomers were barely detectable. The hydrogenation of (-)-menthone, (+)-isomenthone, and (+)-pulegone over SiO2-supported Pt and Pt-Sn catalysts was studied in this work. Reson. Boelens Aroma Chemical Information Service (BACIS), The Netherlands (1996). 19, 365 (1985). A traditional organic chemistry laboratory experiment involves the acid-catalyzed isomerization of (−)-menthone to (+)-isomenthone. Gas chromatography is used to determine the percent isomerization. The hydrogenation of (-)-menthone, (+)-isomenthone, and (+)-pulegone over SiO2-supported Pt and Pt-Sn catalysts was studied in this work. Chem. 5) The observed optical rotation of a mixture of (-)-menthone and (+)-isomenthone with a concentration of 0.0662 g/ml was measured at +0.891° in a 1 decimeter (dm) cell. without permission from the American Chemical Society.
