Solution behaviour of lead(II) carboxylates in organic solvents
Burrows, Hugh D.; Miguel, Maria da Graça; Pereira, Rui P. C.; Proença, Nuno M. B.; Cardoso, Sónia M.C.; Geraldes, Carlos F. G. C.; Gil, M. HelenaThe solution behaviour has been studied of a series of even chain length lead(II) carboxylates (octanoate to octadecanoate) and the odd chain length lead(II) heptadecanoate in a variety of non-complexing organic solvents and in alcohols. In agreement with previous studies, solubility increases dramatically above a certain temperature, which depends on solute concentration, chain length and solvent. This solutio...
Poly(ethylene oxide)-sodium dodecyl sulfate interactions studied using static a...
Brown, Wyn; Fundin, Johan; Miguel, Maria da GraçaStatic and dynamic light scattering measurements have been made on poly(ethy1ene oxide) (PEO) in the presence of the ionic surfactant sodium dodecyl sulfate (SDS) in aqueous solution over a range of relative concentrations. The purpose was, in part, to demonstrate the polyelectrolyte effecte which arise in PEO on formation of the charged complex between the components in solution in which small SDS micelles are...
