Thermochemical studies of N-methylpyrazole and N-methylimidazole.
The 351.1 nm photoelectron spectra of the N-methyl-5-pyrazolide anion and the N-methyl-5-imidazolide anion are reported. The photoelectron spectra of both isomers display extended vibrational progressions in the X2A' ground states of the corresponding radicals that are well reproduced by Franck-Condon simulations, based on the results of B3LYP/6-311++G(d,p) calculations. The electron affinities...
متن کاملReduction of 4-methylimidazole in caramel coloring by ɣ-irradiation
4-Methylimidazole (4-MEI) is a simple nitrogen-containing heterocyclic compound, and recently classified as group 2B by International Agency for Research on Cancer (IARC). Caramel coloring is widely applied food coloring in many food products including coffee, carbonated beverages, beer and wine. In present study, ɣ-irradiation was applied to Caramel Color III to reduce the level of 4-MEI witho...
متن کاملN-Methylimidazole Promotes the Reaction of Homophthalic Anhydride with Imines
The addition of N-methylimidazole (NMI) to the reaction of homophthalic anhydride with imines such as pyridine-3-carboxaldehyde-N-trifluoroethylimine (9) reduces the amount of elimination byproduct and improves the yield of the formal cycloadduct, tetrahydroisoquinolonic carboxylate 10. Carboxanilides of such compounds are of interest as potential antimalarial agents. A mechanism that rationali...
متن کاملDetermination of 4-methylimidazole in caramel color by capillary isotachophoresis.
A method for the determination or 4-methylimidazole in caramel color, based on cationic separation of the sample by capillary isotachophoresis, is described. No pretreatment of the sample is necessary and the detection limit was found to be 5 ppm.
متن کاملDistribution of N-Methylimidazole in Ionic Liquids/Organic Solvents Systems
The partition coefficients, Kmim, of N-methylimidazole (mim) in two-component systems composed of ionic liquid (IL) and a series of organic solvents immiscible with ILs (butyl acetate, ethyl acetate, tert-butyl methyl ether, diethyl ether and cyclohexane) were determined by a shake-flask method. The influence of different factors such as temperature, solvent polarity, mim concentration, and wat...
