Environmental and biological tin and lead chemistry
Healy, Michael Anthony (1980) Environmental and biological tin and lead chemistry. PhD thesis, University of Nottingham.
Tin and lead are metals of considerable commercial importance and are used in many forms in the environment. Heat and light stabilization of polyvinylchloride polymer by organotins is now a principle application of that metal. The spectroscopic properties and crystal structures are determined for some estertin precursors of these stabilizers: mono and bis-(beta-carbomethoxyethyl) tin chlorides, as well as the bis-(beta-carbomethoxyethyl) tin dichloride analogue. The feasibility of using Mössbauer spectroscopy to determine the fate of the organotin species within the PVC is also assessed. The INDOR technique is used to obtain tin-119 n. m. r. data for a series of trimethyl and dimethyltin(IV) compounds and the results interpreted in a manner illustrating the use of this method as a structural probe for the solution chemistry of organotin systems.
