Synthesis of Chlorinated Bicyclic Adduct as Biocids for Sulfate-Reducing Bacteria

Synthesis of bicyclic systems containing chlorine atoms, and/or ether groups in aromatic rings can be con- sidered as an important method for building bicyclic system and production of new adducts. One of the most important types in the cycloaddition reaction is the Diels-Alder reaction (1,4 cycloaddition). In the present investigation a new ether of allylic type (dienophile) p-allyl bromo phenol was prepared and its structure was confirmed by molecular weight determination, refractive index, infrared spectra, and density. A new adduct was obtained by means of 1,4 cycloaddition reaction of hexachlorocyclopentadiene (HCP) and the new pre- pared dienophile. The reaction takes place without using solvent, catalysts, or elimination of any compound. The effect of variations in temperature, initial molar ratio and reaction duration were studied to determine the optimum conditions of the reaction. The optimum conditions reached were reaction temperature recorded 140?C, initial molar ratio diene: dienophile was 3:1 and the reaction duration time reached 6 h. Under these optimum conditions the maximum yield was 78%. The new adduct revealed very high biological effect as sulfate-reducing bacteria (SRB).

Optical mesoscopic membrane sensor layouts for waterfree and blood-free toxicants

与阳极的氧化铝膜( AAM ) nanochannels 导致了的在内的唯一的结构和形态学在 mesoscopic 膜传感器的制造进展为检测，设想，吸附，过滤，并且恢复有毒的金属离子的极端踪迹的集中的各种各样的方法的发展，例如水和血里的 Hg 2+和 Pb 2+,。这些经常，一个壶屏蔽方法在常规方法上提供优点因为他们不要求复杂仪器或勤劳样品准备。在现在的学习，我们在生物、环境的样品为 Hg 2+ 和 Pb 2+ 的裸体眼睛的察觉，识别，过滤，和恢复制作了二个 mesoscopic 膜传感器。这些传感器被器官的颜料的稠密的固定在作为脚手架用 AAM 的 nanochannels 被构造的硅石 nanotubes 的 mesopore 表面上描绘。我们证实 nanotubes 沿着 AAM nanochannels 的长轴是面向的，在两结束开，并且完全并且一致地充满了器官的颜料；另外，器官的颜料的稠密的固定没影响 ion-to-ligand 绑定事件的速度。我们使用了简单，台式，为 Hg 的察觉，移动，和过滤估计发达的膜传感器的适用性的流动彻底地试金关于再循环能力的 2+ 和 Pb 2+ 并且连续监视。从生物液体的目标离子的移动借助于流动 cytometric 分析被估计。我们的结果表明我们的膜传感器的潜力被用于阻止在环境和血与暴露联系到有毒的金属离子的健康风险。
