Organoclays are hybrids derived from an ion exchange of hydrophilic clays with quaternary ammonium salts. The exchange makes the clay hydrophobic and enables it to swell in non-aqueous systems; because of this property, organoclays are widely used as rheological additives in paints, inks, cosmetics and as pollutant absorbing agents in soil remediation programs. We studied the manufacturing process of organic-clay hybrids using one natural (Na-montmorillonite) and several synthetic clays (Na-fluorophlogopites) as precursors: organoclays prepared from synthesized clays are characterized by higher purity and reproducibility as well as specifically designed features. We prepared the organoclays using both conventional-hydrothermal and microwave hydrothermal processes, in order to compare the results obtained with two different heating methods under the same reaction conditions. We found that there are no significant differences in terms of kinetics of intercalation with lower-charged clays, while microwaves can lead to better results in the treatment of higher-charged clays.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1119-97-7, and how the biochemistry of the body works.Reference of 1119-97-7

Polyelectrolytes (PEs) possibly occur in the form of a pearl-necklace structure in poor solvents. This structure, characterized by the form of segregated beads connected by narrow strings, has been extensively studied by scaling analysis and computer simulation, and was believed to be formed by the Rayleigh instability mechanism. However, the structure has not been experimentally well studied, and a complete experimental picture on the necklace formation is still not available. In this study, pearl-necklace structures of DNA induced by different condensing agents are observed by atomic force microscopy. The results show that the formation of a pearl-necklace conformation is highly dependent on kinetic factors such as incubation time and thermodynamic factors including the concentration and condensing ability of the agent. If the incubation time is sufficiently short, this conformation can exist as an intermediate state of the DNA coil?globule transition. When agents with weaker crowding effect or screening ability are added, the structure appeared to be thermodynamically stable. The same effect was observed in rather low concentrations of agent. A rods-on-a-string structure, unlike the common characterized spherical beads-on-a-string conformation, was observed and was believed to result from the stiffness of DNA.

Previous work in our group has shown that hydrophobic modification of chitosan and Nafion membranes can be used to alter the transport properties of chemically modified electrodes. In this paper, we employ the same hydrophobically modified chitosan and Nafion membranes to form and characterize enzyme modified electrodes for biofuel cell applications. This paper details the voltammetric characterization of the electrochemical flux at alcohol dehydrogenase, formate dehydrogenase, lactic dehydrogenase, glucose dehydrogenase, and formaldehyde dehydrogenase modified glassy carbon electrodes, where the enzymes were immobilized in both hydrophobically modified Nafion and chitosan membranes where the degree of hydrophobic modification was systematically altered. The results conclude that the electrochemical flux is a function of both the transport and extraction properties of the membrane, as well as the size and catalytic activity of the enzyme. Finally, this paper details the first evidence that hydrophobically modified chitosan can be used at the anode of a biofuel cell.

The polymerization of [Ge4S10]4- and [Ge4Se10]4- unit clusters with the divalent metal ions Zn2+, Cd2+, Hg2+, Ni2+, and Co2+ in the presence of various surfactant cations leads to novel mesostructured phases. The surfactants are the quaternary ammonium salts C12H25NMe3Br, C14H29NMe3Br, C16H33NMe3Br, and C18H37NMe3Br, which play the role of templates, helping to assemble a three-dimensional mesostructured metal-germanium chalcogenide framework. These materials are stoichiometric in nature and have the formula of (R-NMe3)2[MGe4Q10] (Q = S, Se). The local atomic structure was probed by X-ray diffuse scattering and pair distribution function analysis methods and indicates that the adamantane clusters stay intact while the linking metal atoms possess a tetrahedral coordination environment. A model can be derived, from the comparison of measured and simulated X-ray powder diffraction patterns, describing the structure as an amorphous three-dimensional framework consisting of adamantane [Ge4Q10]4- units that are bridged by tetrahedral coordinated M2+ cations. The network structures used in the simulations were derived from corresponding disordered structures developed for amorphous silicon. The frameworks in (R-NMe3)2[MGe4Q10] are perforated with worm hole-like tunnels, occupied by the surfactant cations, which show no long-range order. This motif is supported by transmission electron microscopy images of these materials. The pore sizes of these channels were estimated to lie in the range of 20-30 A, depending on the appointed surfactant cation length. The framework wall thickness of ca. 10 A is thereby independent from the surfactant molecules used. Up to 80% of the surfactant molecules can he removed by thermal degradation under vacuum without loss of mesostructural integrity. Physical, chemical, and spectroscopic properties of these materials are discussed. (C) 2000 Academic Press.

Hollow silica microspheres (HSMs) with different structures have been synthesized using sacrificed hard template route combined with multiple sol?gel silica shell coating steps. The synthesized HSMs were characterized by SEM and N2 sorption measurements and employed as the stationary phase in thin layer chromatography. Thin layers of HSMs were coated on glass slides and used to separate a model mixture of methyl red and dimethyl yellow. The conditions to achieve the best chromatographic separation efficiency of the synthesized HSMs were optimized. The results show that the organic mixture could be well-separated using the mixture of cyclohexane/toluene/ethanol as the mobile phase. Distilled water was the best mixing agent for the preparation of the thin layer plates. Activation of the plates at 105 C for 1 h improved the separation efficiency. Under the optimized conditions, the effect of the microstructures of HSMs on the separation efficiency was analyzed. It is shown that the separation efficiency mainly depends on the thickness of the silica shells and the pore size gradient of the nanopores inside the shells. A comparison test shows that HSMs as a stationary phase are advantageous over commercial silica gel in an easy preparation of homogeneous TLC thin plates.

The effects of cationic surfactants of cetyl trimethyl ammonium bromide (CTAB), tetradecyl trimethyl ammonium bromide (TTAB) and cetyl pyridinium chloride (CPC) on the kinetics of intramolecular general base catalyzed hydrolysis ([OH-] range 0.05-0.1 mol L-1) of phenyl salicylate have been studied at different temperatures. The rate is independent of [OH-] in the studied range. The anionic surfactant sodium dodecyl sulphate (SDS) has no effect on the rate. The presence of small amount of any of these cationic surfactants well below its critical micelle concentration markedly inhibits the rate of reaction suggesting a pre-micellar aggregation between the substrate and surfactant monomers. The kinetic data have been analyzed in terms of earlier reported models (Piszkiewicz’s co-operativity model and Raghavan and Srinivasan’s model) for micellar catalysis. The binding constants between the substrate and the surfactants evaluated from the two models are in good agreement. Three dimensional structure of the pre-micellar aggregate controls the approach of the nucleophile water molecule to the reaction center. The planar structure of the pyridinium head group of CPC provides less steric hindrance to the attacking water molecule that leads to the least enthalpy of activation for CPC among the three surfactants. The association between the negatively charged substrate and the cationic surfactant is favored owing to electrostatic as well as hydrophobic interactions. The binding between the substrate and pre-micelles follows the order: CPC > TTAB > CTAB.

The kinetics of the diazotization reaction of procaine in the presence of anionic micelles of sodium dodecyl sulfate (SDS) and cationic micelles of cetyltrimethyl ammonium bromide (CTAB), dodecyltrimethyl ammonium bromide (DDTAB) and tetradecyltrimethyl ammonium bromide (TDTAB) were carried out spectrophotometrically at lambdamax=289nm. The values of the pseudo first order rate constant were found to be linearly dependent upon the [NaNO2] in the concentration range of 1.0×10-3moldm-3 to 12.0×10-3moldm-3 in the presence of 2.0×10-2moldm-3 acetic acid. The concentration of procaine was kept constant at 6.50×10-5moldm-3. The addition of the cationic surfactants increased the reaction rate and gave plateau like curve. The addition of SDS micelles to the reactants initially increased the rate of reaction and gave maximum like curve. The maximum value of the rate constant was found to be 9.44×10-3s-1 at 2.00×10-3moldm-3 SDS concentration. The azo coupling of diazonium ion with beta-naphthol (at lambdamax=488) nm was found to linearly dependent upon [ProcN2+] in the presence of both the cationic micelles (CTAB, DDTAB and TDTAB) and anionic micelles (SDS). Both the cationic and anionic micelles inhibited the rate of reactions. The kinetic results in the presence of micelles are explained using the Berezin pseudophase model. This model was also used to determine the kinetic parameters e.g. km, Ks from the observed results of the variation of rate constant at different [surfactants].

Microbial oil is drawing increasing interest worldwide as an alternative non-food oil feedstock for biodiesel industry. Nowadays researchers have been increasingly focused on the improvement of microbial oil production process. Oleaginous yeast Rhodosporidium toruloides (R. toruloides) is considered an important candidate due to its excellent capabilities of lipid accumulation, broad adaptabilities to various carbon substrates, and the potential of co-production of some pigments. In present work, the individual effects of non-ionic, cationic, and anionic surfactant on cell growth and lipid accumulation of R. toruloides were investigated for the first time. Interesting results were noticed when some anionic surfactants were supplemented. The most significant effect was observed with addition of 0.2 % (w/v) sodium lignosulfonate, that biomass concentration, lipid concentration, and lipid yield was increased by 25.1, 44.9, and 15.7 %, respectively. The fatty acid compositions of R. toruloides lipids remained unchanged, which is similar to that of vegetable oils, and is considered potential feedstock for biodiesel preparation.

This study concerns the adsorption properties of organo-bentonites obtained through the modification performed at 25%, 50% and 100% of the cation exchange capacity (CEC) using tetradecyl trimethylammonium bromide (TDTAB) and hexadecyl trimethylammonium bromide (HDTAB). According to the XRD measurements, TDTAB and HDTAB form bilayers between the silicate layers when the montmorillonite surface is modified by 100% CEC. At 25% and 50% CEC, a random interstratification of monolayer and bilayer structures is observed. The surface area of bentonite decreases upon modification. The adsorption properties of organo-bentonites were tested using phenol as a model pollutant. Batch kinetic and isotherm studies were conducted over the concentration range from 50 to 1000 ppm at pH of 5.5. The adsorption excess isotherms of bentonites show different regions. A considerable increase was observed in the adsorption efficiency of montmorillonite modified with HDTAB at 100% CEC.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 1119-97-7, you can also check out more blogs about1119-97-7
