The invention relates to a process for producing a process for producing 1,1,1,5,5,5-hexafluoroacetylacetone. This process includes (a) hydrolyzing a metal complex of 1,1,1,5,5,5-hexafluoroacetylacetone into a 1,1,1,5,5,5-hexafluoroacetylacetone hydrate; and (b) dehydrating the hydrate into the 1,1,1,5,5,5-hexafluoroacetylacetone. It is possible by this process to recover 1,1,1,5,5,5-hexafluoroacetylacetone with high purity from a material containing a metal complex of 1,1,1,5,5,5-hexafluoroacetylacetone.
本发明涉及一种制备1,1,1,5,5,5-六氟乙酰乙酮的方法。该方法包括(a)将1,1,1,5,5,5-六氟乙酰乙酮的金属配合物水解成1,1,1,5,5,5-六氟乙酰乙酮水合物;以及(b)将水合物脱水成1,1,1,5,5,5-六氟乙酰乙酮。通过该方法,可以从含有1,1,1,5,5,5-六氟乙酰乙酮金属配合物的材料中高纯度地回收1,1,1,5,5,5-六氟乙酰乙酮。
