Growth and characterization of anilinium hydrogen sulfate (AHS) single crystals: An organic nonlinear optical material

Single crystals of anilinium hydrogen sulfate (C6H 8N+·HSO4-, AHS) have been grown by slow evaporation solution growth technique using water as a solvent. Powder X-ray diffraction (XRD) study has been carried out to determine the lattice parameters. Fourier transform infrared (FT-IR) and FT-Raman studies confirm the presence of various functional groups present in the grown crystal. The absorption spectrum of the titled crystal shows that the lower cut off wavelength lies at around 300 nm. The thermal analysis (TG/DTA and DSC) and Polarized light thermomicroscopy (PLTM) were carried out to find the thermal stability, melting point and phase transition of the title crystal. The second-order nonlinear optical (NLO) property of the grown crystal has been confirmed by Kurtz-Perry powder technique. First static hyperpolarizability and molecular orbital calculations were carried out using Gaussian 03W program based on B3LYP/3-21G basis set.

Onium Sulfates and Hydrogen Sulfates: Products of Reactions of Sulfur(IV) Oxide with Aqueous Solutions of Alkylamines and Aniline

The reaction products formed in the SO2–L–H2O–O2 systems (L is n-propylamine, n-butylamine, tert-butylamine, n-heptylamine, n-octylamine, aniline) were isolated and identified as “onium” salts [n-C3H7NH3]2SO4, [n-C4H9NH3]2SO4, [t-C4H9NH3]2SO4, [n-C7H15NH3]3SO4(HSO4), [n-C8H17NH3]3SO4(HSO4), and [C6H5NH3]2SO4. The products were characterized by elemental analysis, IR and Raman spectroscopy, mass spectrometry, and thermogravimetry.

High-throughput approach for the identification of anilinium-based ionic liquids that are suitable for electropolymerisation

We report the synthesis of new protic ionic liquids (PILs) based on aniline derivatives and the use of high-throughput (HT) techniques to screen possible candidates. In this work, a simple HT method was applied to rapidly screen different aniline derivatives against different acids in order to identify possible combinations that produce PILs. This was followed by repeating the HT process with a Chemspeed robotic synthesis platform for more accurate results. One of the successful combinations were then chosen to be synthesised on a larger scale for further analysis. The new PILs are of interest to the fields of ionic liquids, energy storage and especially, conducting polymers as they serve as solvents, electrolytes and monomers at the same time for possible electropolymerisation (i.e. a self-contained polymer precursor).

Semi-organic salts of aniline with inorganic acids: Prospective materials for the second harmonic generation

Three novel inorganic salts of aniline with sulfuric and selenic acids were prepared and characterized by X-ray structural analysis. Anilinium(1+) selenate, (C6H5NH3 +) 2SeO4 2-, and anilinium sulfate, (C 6H5NH3 +)2SO 4 2-, crystallize in the monoclinic space group C2. The crystal structures are based on hydrogen bonded layers of alternating anilinium cations and inorganic anions. Anilinium(1+) selenate dihydrate, (C 6H5NH3 +)2SeO 4 2-·2H2O, crystallizes in the monoclinic space group C2/c. The crystal structure is formed by a network of alternating anilinium cations, selenate anions and water molecules connected by a system of intermolecular hydrogen bonds. The FTIR and Raman spectra of all the compounds have been recorded and discussed as well as their crystal structures. According to the DSC curves and temperature dependence of lattice parameters, anilinium sulfate exhibits phase transitions at 217 and 182 K. The appropriate changes of vibrational spectra were also recorded during cooling of the sample especially in the N-H stretching and sulfate antisymmetric stretching (ν3 SO4 2-) spectral regions. The quantitative measurements of the second harmonic generation at 1064 nm were performed using powdered samples of anilinium sulfate, anilinium chloride and anilinium selenate, and the relative efficiencies deff = 0.05dKDP, deff = 2.33dKDP and deff = 0.05dKDP (KDP; i.e. KH 2PO4) have been observed, respectively.

Sulfonation of arylamines Part 9 - Solid state synthesis of di-ortho ring substituted aminobenzenesulfonic acids

Di-ortho ring substituted arylammonium sulfates (Di-o-RSAS) have been prepared from the corresponding arylamines by treatment with conc. H2SO4 and characterized by elemental, gravimetric and spectral analyses. These sulfates yield the corresponding ring substituted aminobenzenesulfonic acids (RSABSA) when subjected to thermal energy. Non-isothermal gravimetric studies on di-o-RSAS support the formation of RSABSA. It is observed that most of the salts undergo transformation to acid in solid state via proton transfer reaction prior to sulfonation.

Preparation of acetalized azo dyes

Acetalized azo dyes are prepared by diazotizing an amine, coupling with a hydroxyalkyl-containing coupling component and subsequently reacting with a vinyl ether in a process which comprises carrying out the coupling reaction in a two-phase reaction mixture comprising water and an aromatic hydrocarbon, subsequently separating off the aqueous phase and reacting the azo dye, which is present in the organic phase, without intermediate isolation, with a vinyl ether in the presence of a polybasic carboxylic acid as catalyst.

Kinetics of Thermal Decomposition of Dianilinium Sulphate

The thermal decomposition of arylammonium sulphate (dianilinium sulphate) has been investigated; sulphanilic acid is found to be the decomposition product.The mean value for the energy of activation (28.27 +/- 0.46 kcal mol-1) for the decomposition has been determined from isothermal TGA data , contracting area, contracting cube, and Jacobs-Kureishy equations.Thus, the decomposition of dianilinium sulphate seems to be controlled by a random nucleation process.The results suggest that the primary step (prior to sulphonation) in the decomposition of this salt is a proton-transfer process.
