Langues : Anglais (eng) Catégories : Benzothiazoles Capteurs (technologie) Caractérisation Diméthylformamide Eau Fluorescence Ions mercure Ions métalliques Solutions aqueuses (chimie) Index. décimale : 667.3 Teinture et impression des tissus Résumé : A simple benzothiazole-based fluorescent probe (TDA) for the determination of Hg2+ ion in aqueous solutions was synthesised in one step and characterised by 1H NMR, 13C NMR, APT, COSY, FTIR, and elemental analysis. TDA shows a significant fluorescence change upon the interaction of Hg2+ ion in DMF–water (v/v = 1/1), while only minor changes in fluorescence intensity are observed with 18 other metal ions. Fluorescence enhancement by a factor of 15 is achieved upon selective interaction with Hg2+ ion. The Hg2+ ion detection process is found to be pH dependent; therefore, TDA could be feasible within a pH range of 4.0–7.0.

Innovative in-can preservation / Dave Ogden in PAINTINDIA, Vol. LXII, N° 2 (02/2012)

[article]  inPAINTINDIA > Vol. LXII, N° 2 (02/2012) . - p. 61-63 Titre : Innovative in-can preservation Type de document : texte imprimé Auteurs : Dave Ogden, Auteur Année de publication : 2012 Article en page(s) : p. 61-63 Langues : Anglais (eng) Catégories : Antimicrobiens Benzothiazoles Formulation (Génie chimique) Pyrithione de zinc Revêtements -- Additifs Index. décimale : 667.9 Revêtements et enduits Résumé : Widely used for 40 years, BIT has become the main building block for in-can preservation but has some perceived weaknesses, which can be overcome by using it in combination with other biocides. Now, by combining BIT with zinc omadine antimicrobial and thus joining an electrophilic activity with a membrane activity, it is possible to create a biocide that can both inhibit the growth bacteria and actively break down the cell membrane.

Synthesis and characterisation of benzothiazole-based solid-state fluorescent azo dyes / Ganapati S. Shankarling in COLORATION TECHNOLOGY, Vol. 126, N° 6 (2010)

These dyes showed a molar extinction coefficient in the range of 20 000–30 000 l/mol/cm. These compounds were characterised by strong solid-state fluorescence under long ultraviolet light (365 nm). Absorption and fluorescence spectra revealed that electron coupling originating from broad Ï€-electron delocalisation and the keto–enol form is responsible for the large Stokes shift. These dyes were readily soluble in common solvents such as dichloromethane, chloroform, dimethyl formamide, tetrahydrofuran and dimethyl sulphoxide and were characterised by means of elemental analysis, proton nuclear magnetic resonance and mass spectrometry. Thermogravimetric analysis of solid-state fluorescent dyes show thermal stability up to 270 °C and can therefore be used for polymer application. The coloristic properties of these dyes were evaluated on polyester by the disperse dyeing method.

Synthesis and evaluation of a novel blue cationic reactive dye for modified nylon 6.6 ‘Tactel Coloursafe’ / Soleimani-Gorgani Atasheh in COLORATION TECHNOLOGY, Vol. 127, N° 4 (2011)

[article]  inCOLORATION TECHNOLOGY > Vol. 127, N° 4 (2011) . - p. 227-234 Titre : Synthesis and evaluation of a novel blue cationic reactive dye for modified nylon 6.6 ‘Tactel Coloursafe’ Type de document : texte imprimé Auteurs : Soleimani-Gorgani Atasheh, Auteur ; John A. Taylor, Auteur Année de publication : 2011 Article en page(s) : p. 227-234 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Benzothiazoles Colorants azoïques Colorants cationiques Colorants réactifs Polyamide 66 Teinture -- Fibres textiles synthétiques Index. décimale : 667.3 Teinture et impression des tissus Résumé : A novel blue cationic reactive dye (dye 1) based on an azo benzothiazole derivative and possessing an acrylamido reactive group, was synthesised and evaluated on dyeing Coloursafe modified nylon 6.6 at optimum pH. Benzothiazole quaternary dye was chosen as a target as this is known to be very strong chromophically. Evaluation of the technical properties of dye 1 showed that it fixed efficiently to nylon under acidic dyeing conditions. As it was necessary to prove that fixation occurs via a covalent bond, the dyeing properties of a non-reactive cationic dye, (CI Basic Blue 41), on dyeing nylon 6.6 at optimum pH were evaluated. CI Basic Blue 41 was similar in structure to dye 1 and would be capable of forming an ion–ion bond with the fibre. Evaluation of the technical properties of dye 1 proved that, in all cases, its fixation efficiency and build-up properties were far better than that of CI Basic Blue 41.

Langues : Anglais (eng) Catégories : Antifongiques Antiseptiques Benzothiazoles Candida Caractérisation Huile de karanja et constituants Huile de neem Savon Surfactants Surfactants -- Toxicologie Tests de toxicité Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Neem (Azadirecta indica) and Karanj (Pongamia pinnata) oils are ecofriendly, non-toxic, completely biodegradable with antiviral, antifungal, and antibacterial properties. The dark green colour Copper(II) soaps derived from Neem and Karanj oil, their greenish brown complexes with ligand 2-amino-6-methyl benzothiazole containing nitrogen and sulphur have been synthesized and characterized by elemental analysis. IR and NMR of complexes suggest that the complexation has taken place successfully. From the analytical data the stoichiometry of the complexes has been observed to be 1:1 (metal-ligand). Copper soaps and their complexes are good anti-fungal agents. The fungi toxicities of the oils, soaps and complexes of neem and karanj have been investigated. The results indicate that the strain of Candida species is susceptible towards complexes of benzothiazole.
