在333K和9.8-29.4 Mpa条件下，乙酰丙酮络合物在超临界二氧化碳(SC-CO2)中的溶解度受萃取压力、金属性质和络合物中乙酰丙酮配体数量的影响很大。研究发现，由于乙酰丙酮络合物在超临界CO2中的溶解度存在显著差异，因此可以通过超临界CO_2处理选择性地提取。
The solubilities of the acetylacetone chelates in supercritical CO2 (SC-CO2) at 333 K and 9.8–29.4 MPa were strongly influenced by the extraction pressure, and by the nature of the metals and the number of acetylacetone ligands in the chelates. It was found that acetylacetone chelates could be extracted selectively by SC-CO2 treatment because of significant differences in their solubilities in SC-CO2.
