AbstractAbstract
[en] Data concerning the reactions of phosphorus ylides with acyl chlorides that occur by different pathways depending on the nature of the ylide or acyl chloride and on the reaction conditions are summarised and systematised. The products of these reactions are of interest as building blocks for the synthesis of other classes of compounds.

AbstractAbstract
[en] The ionization constants of fluorine-containing monothio-β- diketones and β-aminovinylketones with aminogroup near carbon, bonded with fluoroalkyl substituent, are determined spectrophotometrically. The non-inductive effect of the long fluoroalkyl substituents on the ionization constants of monothio-β-diketones is established and the absence of the effect for β-aminovinyl- ketones is shown. Sulphur atom substitution of oxygen of carbonyl group, bonded with non-fluorated substituent decreases the value of pKsub(a) by 2-3 units, while the introduction of nitrogen atom instead of oxygen of carbonyl group, bonded with fluorated substituent, increases them by 7-8 units. The equation, connecting pKsub(a) of fluorine-containing monothio-β-diketones with pKsub(a) of the corresponding β-diketones, is presented

AbstractAbstract
[en] The temperature dependence of the low-energy electron attachment and autodetachment processes for c-C4F6 in a N2 buffer gas has been studied in the temperature, T, range of 300 to 600 K and the mean electron energy, <ε>, range from 0.19 to 1.0 eV. The low-energy electron attachment rate constant for c-C4F6 shows only a slight dependence on gas temperature. In contrast, the autodetachment frequency increases by more than four orders of magnitude when T is increased from 300 to 600 K. This increase in autodetachment is due to the increase in the internal energy content of the c-C4,F6- anion with increasing T. The autodetachment process under consideration is a heat-activated process and has an activation energy E* of 0.24 eV. Significance of these results to gaseous dielectrics is indicated

AbstractAbstract
[en] We present a case study for a former fire fighter training campus with widespread PFAS impacts. A management response is currently underway at the site, including the scraping and excavation of areas of elevated PFAS concentrations, with these soils to be managed on-site. Complete ‘source’ removal is recognised to be impracticable for the site given the scale of the site and the widespread (>150 ha) low-level impacts. In order to provide an efficient and achievable response, it was necessary to assess excavation extent which would effectively manage potential risks. On this basis, rehabilitation goals have been developed for the site which are less stringent than the PFAS National Environmental Management Plan (NEMP), but which have been assessed (on a holistic, whole-of-site basis) to offer an appropriate level of protection to receptors associated with the site. A key objective for the site considered in the rehabilitation goals is the management of risks to on-site terrestrial ecological receptors. A site-specific review was undertaken to better understand the receptors on-site requiring protection, allowing refined screening levels to be selected. A preliminary risk assessment was then undertaken, considering the predicted final site condition (depth and extent of residual PFAS impacts) to estimate potential risks to terrestrial ecological receptors post-rehabilitation.

AbstractAbstract
[en] The work done at the Institute for Hot Atom Chemistry is concerned with research and development in the field of nuclear fuel reprocessing. The activities are guided by the aims of the planned back end fuel cycle facility. They are performed in contact with the companies DWK, KEWA and GWK within the scope of the projects reprocessing and waste management and fast breeder development. The Institue consists of the following divisions: extraction chemistry and plant operation; process analyzing; chemical process and apparatus development; dissolver and waste gas treatment; process control and automation; organic analysis; basic research.
