乙酰丙酮 (CAS No.123-54-6)
- 物化性质
- 常温下为无色或淡黄色透明液体，有类似乙醚或丙酮的轻微刺激性气味；具有酮-烯醇互变异构性。沸点约138.4℃（常压），熔点-23℃。20℃时密度约0.975 g/cm³，黏度约1.16 mPa·s。易溶于水（20℃溶解度约12 g/100mL），可与乙醇、乙醚、苯、氯仿等多数有机溶剂混溶。纯品在常温下较稳定，遇强酸、强碱易分解，长期储存或光照可能缓慢变色。

Product Name:Acetylacetone
English Name:Acetylacetone
CAS No.:123-54-6
Aliases:2,4-Pentanedione, Diacetylmethane, Hacac
Molecular Formula:C5H8O2
Physical Properties:A colorless to light yellow transparent liquid at room temperature with a mild irritating odor similar to ether or acetone; exhibits keto-enol tautomerism. Boiling point approximately 138.4°C at normal pressure, melting point -23°C. Density approximately 0.975 g/cm³ at 20°C, viscosity approximately 1.16 mPa·s. Soluble in water (approximately 12 g/100 mL at 20°C) and miscible with most organic solvents such as ethanol, ether, benzene, and chloroform. Stable at room temperature as a pure substance, but decomposes in strong acids and alkalis; may slowly discolor on prolonged storage or light exposure.
Uses:Primarily used as an organic synthesis intermediate for preparing heterocyclic compounds such as pyrrole, furan, and pyrimidine, as well as fragrances, food additives, pharmaceuticals, and pesticides. As a metal chelating agent, it forms stable chelates with rare earth and transition metals, and is used for metal ion extraction and separation, wastewater treatment, and catalyst preparation. It is also widely used as a chromogenic reagent in analytical chemistry and as a precursor for electronic materials.
