Photoemission and conductivity measurement of poly(N‐methyl aniline) and poly(N‐ethyl aniline) films

The studies involve the X‐ray photoelectron spectroscopy (XPS) and conductivity measurements of poly(N‐methyl aniline) and poly(N‐ethyl aniline) films deposited electrochemically at different pH values of −0.96, 2.22, and 3.78 for N‐methyl aniline and 1.10, 2.22, and 3.78 for N‐ethyl aniline. The results obtained reveal significant differences in the film properties of the two matrices as a function of pH of solution. These differences are explained on the basis of the competitive reaction products formed during polymerization in the two matrices along with the differences in the electron‐donating ability of the methyl and ethyl groups present on the nitrogen (N) atom. These results are further supported by the UV–Visible and IR data. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 74: 1286–1292, 1999     

The Hydroamination of methyl acrylates with amines over zeolites

H-form zeolites, H-FAU and H-BEA have been studied as heterogeneous catalysts for the hydroamination. They catalyzed the reaction of methyl acrylate with aniline to give N-[2-(methoxycarbonyl)ethyl]aniline (1) as a main product. H-BEA and H-FAU zeolites efficiently catalyzed the hydroamination to afford anti-Markovnikov adduct as a main product. The conversion of aniline around 55–85% was achieved within 18 h over H-BEA and H-FAU zeolites with SiO₂/Al₂O₃ molar ratio of 25–30; however, the formation of N,N-bis[2-(methoxycarbonyl)ethyl]aniline (2) as a product of double addition of methyl acrylate to aniline has also been observed as a by-product over H-BEA and H-FAU catalysts. The influences of the reaction parameters such as temperature and catalyst amount, and type of α,β-unsaturated esters and amines have been also investigated.

Kinetic study of reactions of aniline and benzoyl chloride in a microstructured chemical system

The reaction between aniline and benzoyl chloride is well known for producing high performance polymers and chemicals. But the fast main reaction and reversible consecutive side reaction make process rather complicated and no thorough kinetics study has ever been reported before. A microstructured chemical system, consisting of a micromixer, preheat exchange coiled capillaries, a delay loop, and a microhydrolyzer, was designed to carry out this reaction using N‐methyl‐2‐pyrrolidone as the solvent. A kinetic model was established, and the values of kinetic constants, pre‐exponential factors and activation energies of each reaction as well as their confidence intervals were acquired. With this model each substance concentration vs. residence time were obtained to help understand reaction process and further optimize operating conditions. Compared to earlier reports on this reaction, this microstructured chemical system provides more accurate parameters and can develop a reliable platform for kinetic study of similar chemical reactions. © 2015 American Institute of Chemical Engineers AIChE J, 61: 3804–3811, 2015

NMR investigation of aniline oligomers produced in the oxidation of aniline in alkaline medium

The chloroform‐soluble products of aniline or (¹⁵N)aniline oxidation in alkaline medium were analysed using one‐ and two‐dimensional ¹H NMR, ¹³C NMR and ¹⁵N NMR spectroscopy. Among the products, two were found to be prominent, namely a carbonyl‐containing semiquinonoid and a phenazine‐like structure. The probable mechanism of their formation is suggested.
