Due to the surface-active properties of copper(II) stearate with 2-aminobenzothiazole, the complexes exhibit many applications in agrochemical industries as dispersing agents, foaming and wetting agents. In the present investigation solid complexes of Cu(II) stearate with 2-amino-6-methoxybenzothiazole and 2-amino-6-nitrobenzothiazole have been synthesized and characterized by elemental analysis and their IR, NMR, ESR spectral studies. All the synthesized complexes are coloured and their purity was checked by Thin Layer Chromatography.

Synthesis and ultraviolet-visible spectroscopic and electrochemical analyses of dyes derived from 2-aminobenzothiazole, and study of their adsorption on titanium dioxide / Anna Maruszewska in COLORATION TECHNOLOGY, Vol. 130, N° 4 (08/2014)  

[article]  inCOLORATION TECHNOLOGY > Vol. 130, N° 4 (08/2014) . - p. 243-249 Titre : Synthesis and ultraviolet-visible spectroscopic and electrochemical analyses of dyes derived from 2-aminobenzothiazole, and study of their adsorption on titanium dioxide Type de document : texte imprimé Auteurs : Anna Maruszewska, Auteur ; Radoslaw Podsiadly, Auteur Année de publication : 2014 Article en page(s) : p. 243-249 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Aminobenzothiazoles Colorants -- Adsorption Dioxyde de titane Electrochimie Spectroscopie ultraviolette Index. décimale : 667.3 Teinture et impression des tissus Résumé : A series of Schiff bases with hydroxyl anchoring group/s in various positions were synthesised. Their visible light absorption and electrochemical and physicochemical adsorption properties were investigated. Results show that the studied compounds have adequate highest-occupied-molecular-orbital and lowest-unoccupied-molecular-orbital levels that match with the conduction band of titanium dioxide and the redox potential of the electrolyte. Adsorption of azomethine compounds with hydroxyl group/s on titanium dioxide was studied. Experimental data show that the introduction of two ?-hydroxyethyl groups can greatly enhance the adsorption efficiency of the studied Schiff base on titanium dioxide. Sorption kinetics was measured for di-(?-hydroxyethyl)aminobenzyliden-2-aminobenzothiazol. Results show rapid initial sorption (<30 min), followed by a slower rate of increasing uptake between 0.5 and 6 h. Kinetic data were modelled using pseudo-first-order, pseudo-second-order, and intraparticle diffusion kinetics equations. These results indicate that the pseudo-second-order equation and intraparticle diffusion model can better describe the adsorption kinetics of di-(?-hydroxyethyl)aminobenzyliden-2-aminobenzothiazol onto titanium dioxide.
