The pharmacological properties of tertiary sulphonium salts appear to be similar to those of quaternary ammonium salts. The trimethyl+ sulphonium ion, Me3S, resembles the tetramethyl+ ammonioum ion, Me N in its ability to paralyse the frog sartorius preparation (Ing and Wright, 1933): decamethylene bisdimethylsulphonium + + Me2S-(CH2)10-SMe2, resembles decamethonium, + + Me3N-(CH2)0-NMe3, in it...

The impact of the nonionic surfactant, dodecyl triethyleneglycol ether (C(12)E(3)) on the solution microstructure of the dialkyl chain cationic surfactant, dihexadecyl dimethyl ammonium bromide, (DHDAB) has been investigated. The variation in solution microstructure has been studied using a combination of small angle neutron scattering, ultra small angle neutron scattering, optical texture and ...

The dual template synthesis of zeolite SSZ-13 by use of trimethyl-adamantanammonium hydroxide and a diquaternary-ammonium mesoporogen induces considerable mesoporosity without impeding zeolite microporosity. The strongly improved accessibility of Brønsted sites in mesoporous SSZ-13 increases its stability during application as an acid catalyst in the methanol-to-olefins reaction.

Acacia gum (AG) was grafted with polyacrylamides different catonic ratios obtained by using amounts of acrylamide (AM) and methacrylatoethyl trimethyl ammonium chloride (DMC (cationic monomer)). The thermal properties these products were investigated differential scanning calorimetry (DSC) thermogravimetric (TGA) analyses. formation confirmed FTIR spectroscopy analysis. effects cationic polyacr...

Drug resistance (especially multiple drug resistance) in Mycobacterium tuberculosis makes global concerns in treatment and control of tuberculosis. Rapid diagnosis of drug resistant strains of the bacteria has vital importance in the prognosis of the disease. The aim of this study was to identify the mutations responsible for drug resistance in Mycobacterium tuberculosis strains derived from pa...

In this research, processed or low samples containing corn products (corn semolina, flour, etc.) and soybean were randomly collected from the market, 25 in total (chips, nuts, cereals, flour) analyzed for genetic modification using DNA based detection method, polymerase chain reaction. First, homogenization of was performed. Then isolation done by Cetyl Trimethyl Ammonium Bromide (CTAB) Roche H...

Iron-based oxide catalysts for the NH3–SCR (selective catalytic reduction of NOx by NH3) reaction have gained attention due to their high activity and structural adjustability. In this work, iron–niobium, iron–titanate iron–molybdenum composite oxides were synthesized a co-precipitation method with or without assistance hexadecyl trimethyl ammonium bromide (CTAB). The CTAB (FeM0.3Ox-C, M = Nb, ...

The kinetic studies for copper-catalyzed homocoupling phenylboronic acids (1a-d) have been successfully carried out in an aqueous micellar medium under environmentally benign conditions (water as a solvent, micelle to help solubilize hydrophobic adducts) this study cetyl trimethyl ammonium bromide (CTAB ) is used surfactant produce micelle. Using different copper salts and complexes catalysts m...

The title compound, [Fe(C5H5)(C21H24NPS)]I·CHCl3, is built up from a (ferrocenylmeth-yl)trimethyl-ammonium cation, a iodine anion and a chloro-form solvent mol-ecule, all residing in general positions. The N atom of the ammonium group is displaced by 1.182 (2) Å from the plane of the substituted cyclo-penta-dienyl (Cp) ring towards the Fe atom, whereas the C atom attached to the same Cp ring is...
