The present invention relates to novel compounds which contain no sulfur or chlorine, and which thus contribute to the cleaning of the environment as organo-metal complexes used in metal pastes, etc., and a method for manufacturing the same.
Metal acetylide compounds expressed by the general formula M(-C≡C-R)n (in the formula, M indicates a metal atom, n indicates the valence number of the metal atom M, and R indicates a hydrocarbon group with 1 to 8 carbon atoms which may or may not contain an oxygen atom) are provided as novel organo-metal complexes. Since these compounds contain no sulfur or chlorine, there is no release of sulfurous acid gas or chlorine compounds when the compounds are used in metal pastes, etc., even if the pastes are fixed. Accordingly, these compounds contribute to the cleaning of the environment.
In the present invention, solid sulfites are used as metal reducing agents; accordingly, simple stoichiometric control of the reaction is possible, so that metal acetylide compounds can easily be obtained. Furthermore, since no sulfurous acid gas is generated in this manufacturing method, there are no concerns about environmental pollution, and the method contributes to the cleaning of the environment.
本发明涉及不含硫或氯的新型化合物,因而有助于净化环境,可作为有机金属络合物用于金属浆料等,本发明还涉及制造这种化合物的方法。
本发明提供了通式为 M(-C≡C-R)n(式中,M 表示金属原子,n 表示金属原子 M 的价数,R 表示具有 1 至 8 个碳原子的烃基,其中可能含有氧原子,也可能不含有氧原子)的金属乙酰化合物作为新型有机金属络合物。由于这些化合物不含硫或氯,因此在金属浆料等中使用这些化合物时,即使浆料是固定的,也不会释放亚硫酸气体或氯化合物。因此,这些化合物有助于清洁环境。
在本发明中,固体亚硫酸盐被用作金属还原剂;因此,可以对反应进行简单的化学计量控制,从而轻松获得金属乙酰化合物。此外,由于这种制造方法不会产生亚硫酸气体,因此不存在环境污染问题,有助于净化环境。
