The present invention provides an improved, economical and environmentally benign process for metal complexes of acetylacetone having the general formula, M(acac)
n
wherein M is a metal cation selected from the group consisting of Fe, Co, Ni, Cu, Zn, Al, Ca, Mg, Mo, Ru, Re, U, Th, Ce, Na, K, Rb, Cs, V, Cr, and Mn etc., n is an integer which corresponds to the electrovalence of M, are obtained by reacting the corresponding metal hydroxide, metal hydrated oxide or metal oxide with a stoichiometric amount of acetylacetone and separating the product.
本发明提供了一种改进的、经济的和环境友好的过程,用于具有一般公式M(acac)n的乙酰丙酮金属络合物,其中M是从Fe、Co、Ni、Cu、Zn、Al、Ca、Mg、Mo、Ru、Re、U、Th、Ce、Na、K、Rb、Cs、V、Cr和Mn等金属阳离子组成的金属阳离子,n是与M的电价相对应的整数,通过将相应的金属氢氧化物、金属水合氧化物或金属氧化物与适量的乙酰丙酮反应并分离产物获得。
