标题:底栖无脊椎动物对洪泛区湖泊沉积物中毒物和食物组合输入的响应
摘要:泛滥平原湖泊生态系统中的底栖生物群落经常暴露于不同水平的食物和毒物.在单独的研究中观测到通过敏感物种的毒物进行抑制和通过增加机会性物种的食物量进行刺激.因此,本研究的目的是评估底栖无脊椎动物对食物和污染输入的反应.因此,选择了位于荷兰瓦尔河沿岸的七个泛滥平原湖泊,这些湖泊具有不同水平的食物(以浮游植物或大型植物为主)和毒物.敏感的蜉蝣 Ephoron Virgo 和机会性蠓 Chironomus Riparius 对这些沉积物的反应在两个物种的 10 天生长生物测定和 C. Riparius 的 28 天出现实验中进行了评估.随着污染物水平的增加,观测到 E. Virgo 的存活和生长均下降.相比之下,尽管存在有毒物质,但 C. Riparius 对沉积物中的食物数量和质量作出反应.因此,我们得出结论,蠓 C. Riparius 不是评估沉积物毒性的合适测试生物.或者,它被证明是确定沉积物营养价值的合适测试生物.蜉蝣

摘要:A method of preparing tetrabromobenzoate compounds from tetrabromophthalic anhydride by reacting tetrabromophthalic anhydride with alcohol in the presence of a decarboxylation catalyst. The reaction may be carried out in an excess of alcohol, or with a near stoichiometric amount of alcohol by performing the reaction in an inert solvent.

权利人:CLARIANT GMBH
摘要:The invention relates to a process for preparing ethanebis(alkylphosphinic) acids by n a) reacting elemental yellow phosphorus with alkyl halides in the presence of alkali metal hydroxide or of alkaline earth metal hydroxide to give a mixture whose main constituents are the alkali metal salts and/or alkaline earth metal salts of alkylphosphonous, phosphorous, and hypophosphorous acid, n b) liberating alkylphosphonous, phosphorous, and hypophosphorous acid by adding mineral acids, and also at the same time precipitating the alkali metal ions and, respectively, alkaline earth metal ions in the form of their salt of the mineral acids, and then n c) esterifying the alkylphosphonous acid from the mixture of the alkylphosphonous, phosphorous, and hypophosphorous acid, n d) isolating the ester of alkylphosphonous acid from the mixture and hydrolyzing the same to give alkylphosphonous acid, and n e) preparing, from the alkylphosphonous acid, the corresponding ethanebis(alkylphosphinic) acid of the general formula (I) where R 1 and R 2 may be identical or different and are hydrogen, a carboxy group, a carboxylic acid derivative, an unsubstituted or substituted alkyl group having from 1 to 10 carbon atoms, phenyl, benzyl, or alkyl-substituted aromatics, and R 3 and R 4 are identical or different and are an unsubstituted or substituted alkyl group having from 2 to 20 carbon atoms, by free-radical-initiated reaction with alkynes, and also to the use of the ethanebis(alkylphosphinic) acids prepared by this process as starting material for preparing flame retardants and precursors for the synthesis of other phosphorus-containing compounds.

标题 :Polyfluoroalkylthio alcohols, esters and useful compositions therefrom

权利人:CIBA GEIGY CORP
摘要:Polyfluoroalkylthio alcohols and esters thereof are disclosed with utility as intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. The novel alcohols and esters are obtained by a free radical catalyzed addition of polyfluoroalkylthiols to acetylenic alcohols or esters thereof. The alcohols are employed in preparation of fluorine containing polyurethanes which are useful as finishes to provide oil and water repellency to textiles and as additives to plastics to provide mold release and other desirable properties.
