说明

乙酰丙酮（2,4-戊二酮）是一种含有两个羰基和一个活性亚甲基的有机化合物。主要用作合成各种化学衍生物的中间体。它还可以用作聚烯烃的改性剂、缓蚀剂和放射性示踪剂的标记。

一般描述

Acetylacetone (2,4-pentanedione) is an organic compound containing two carbonyl groups and one active methylene group. It is mainly used as an intermediate in the synthesis of various chemical derivatives. It can also be used as a modifier for polyolefins, corrosion inhibitors, and labeling of radiotracers.
 

应用

Acetylacetone can be used as:
  • A multifunctional ligand in the synthesis and feasible functionalization of gold nanoparticles (AuNPs).
  • A reactant to synthesize 9,10-dihydroacridines by reacting with methyl acetoacetate and Morita-Baylis-Hillman acetates.
  • A reagent in the synthesis of ZrO2(zirconium dioxide) via hydrolysis of Zr(OC3H7n)4. Acetylacetone controls the hydrolysis and condensation rates of alkoxides and thus, the nucleation and growth rates of oxides.
