    摘要： PROBLEM TO BE SOLVED: To provide alternative sulfur based corrosion inhibitors overcoming sensitivity to chlorine as the fault of tolyltriaozole widely used as corrosion inhibitors to yellow metal. SOLUTION: The fact that dithiocarbamate compounds are sufficiently strongly effective as sulfur based corrosion inhibitors to be bonded with metals, particularly with copper since they form protective barriers or protective films has been found. Further, the fact that, in the compounds as inhibitors, at the time when the substitutional groups of the aliphatic or aromatic series are changed, remarkably influence is exerted on the performance of being filmed has been found. By optimizing the balance between the hydrophobicity and cubic properties of the shields in the substitutional groups, the improved corrosion inhibitors can be provided. COPYRIGHT: (C)2006,JPO&NCIPI

    摘要翻译： 要解决的问题：提供替代的硫磺基腐蚀抑制剂克服氯的敏感性，因为甲苯三唑的广泛用作黄色金属的腐蚀抑制剂的缺点。 解决方案：二硫代氨基甲酸盐化合物由于形成保护屏障或保护膜已经被发现，因为硫基腐蚀抑制剂与金属特别是铜结合，所以二硫代氨基甲酸酯化合物具有足够强的有效性。 此外，作为抑制剂的化合物在脂肪族或芳香族系列的取代基发生变化的时候，已经发现对被成膜的性能有显着的影响。 通过优化取代基中的屏蔽物的疏水性和立方特性之间的平衡，可以提供改进的腐蚀抑制剂。 版权所有（C）2006，JPO＆NCIPI

    摘要： PROBLEM TO BE SOLVED: To provide an alkali metal dithiocarbamate useful as a rubber vulcanization accelerator, an intermediate therefor, or the like.
    SOLUTION: In producing an alkali metal dithiocarbamate by reacting an amine with carbon disulfide and an alkali hydroxide in water, the dithiocarbamate is produced by adding 0.5 to 20 pts. wt. inorganic carbonate and/or inorganic hydrogencarbonate (e.g., sodium carbonate and sodium hydrogencarbonate) per 100 pts. wt. alkali hydroxide. According to the method, it is possible to easily produce an aqueous solution of the dithiocarbamate used as a rubber vulcanization accelerator, an industrial bactericide, or an intermediate therefor without detriment to its commercial value.

    摘要： PROBLEM TO BE SOLVED: To provide a selenium ion separating agent being used for efficiently separating and removing selenium ion contained in an extremely slight content in an aqueous solution and to provide a method for efficiently separating and removing selenium ion from an aqueous solution containing selenium ion in a low concentration using the agent. SOLUTION: A dithiocarbamate compound having the formula (wherein R1 to R4 independently denote a 6-12C hydrocarbon group) is used as a selenium ion separating agent. Selenium ion is separated and removed from an aqueous solution containing selenium ion by bringing the solution into contact with a solution containing an organic solvent and the dithiocarbamate compound or a porous resin carrying the dithiocarbamate compound.
