Microextraction and gas chromatographic determination of organotin compounds /
… methods for fast and efficient extraction of organotin compounds (OTC) and to prepare and apply the most appropriate technique for the analysis of aqueous samples. In real samples OTC exist in cationic form, are non-volatile and polar, so before gas chromatographic analysis OTC must be …

X-ray and spectroscopic studies of organotin compounds.
A critical survey of organotin chemistry and an outline of the determination of crystal structures by X-ray analysis have been made. Crystallographic and spectroscopic studies have been made of novel organotin compounds, allowing comparison of solid and solution phase structures to be made. …

The fate of organotin biocides in marine antifouling elastomers.
… structural changes undergone by a series of triorganotin biocides when dispersed in neoprene-based marine antifouling elastomers. Chemical speciation using tin-119 nuclear magnetic resonance spectroscopy and gas chromatography, indicate that the majority of the tri-n-butyltin (TBT) biocides are …

Nuclear magnetic resonance studies of organotin and related species
A selection of metal complexes including ligands of the type R3Xn-3M (where X = halide, M = Sn, Pb, n = 0-3) were prepared and studied using multinuclear N.M.R. spectroscopy.

A Mossbauer study of some industrial applications of organotin compounds.
… to study the nuclear environment of several organotin compounds having important industrial applications. For each compound studied structural and co-ordination information has been obtained relating to the mode of action of the organotin compound in its application. Chapters one and two of …

The adsorption of phenolic and organotin compounds by clays and cation exchanged clays
Quaternary ammonium exchanged laponites (Quat-laponites) show selectivity in the adsorption of phenols and chlorinated phenols. Strong adsorbate-adsorbent interactions are indicated by adsorption isotherms. Adsorption of phenols and chlorinated phenols by Quat-smectites is greater than that by the …

Biogeochemistry of Organotin and Organolead compounds in a Forested Catchment in NE-Bavaria, Germany
Organotin-compunds (OTC) and Trimethyllead (TML) have a higher toxicity than their corresponding inorganic forms and may affect the functioning of ecosystems. Little is known about their behaviour and fate in the terrestrial environment. The goal of this thesis was to investigate the …

Investigations of catalyst behaviour in the formation of polyurethanes
The mechanism of urethane formation using organotin carboxylate and titanium acetylacetonate chelate catalysts is investigated using computational and experimental methods. In this work, computational chemistry and statistical experimental design were selected as the computational modelling …

Organotin and osmoregulation: quantifying the effects of environmental concentrations of sediment-associated tri-n-butyltin and triphenyltin on osmoregulatory processes in the European flounder Platichthys flesus (L)
… to environmental concentrations (150 ng triorganotin g<sup>-1</sup> dry weight sediment) of sediment-associated tri-o-butyltin chloride (TBTCl) and triphenyltin chloride (TPhTCl), was examined and quantified. Radiotracers were used to measure hydromineral fluxes, the water balance and …

The chemistry of some heteroaryltin compounds.
… a series of previously unreported heteroaryl organotin compounds bearing thienyl and furyl substituents, where the heteroaryl group is bound to tin via a heteroaromatic ring carbon atom. In particular, compounds bearing, respectively, two and three heteroaryl groups were of greater interest, …
