一般描述
乙醛是一种无色易燃的有机液体。它可以由乙炔水合和乙醇催化氧化产生。主要用于生产乙酸。
乙醛的热分解机理已有报道。它是肝脏中的乙醇代谢产物，可与各种蛋白质共价结合，从而改变肝脏的功能和结构。在水滑石型催化剂存在下的乙醛和庚醛的醇醛缩合已有所介绍。
应用
乙醛可用于酶促合成脂肪酸。
生物医学应用里，关于生产具有细胞粘合性和排斥性的纤维状生物材料的研究中，乙醛可用于在等离子体聚合中将反应性醛基沉积到基质上。在采用气相色谱-火焰离子化检测法（GC-FID）测定全血、玻璃状液、尿液等不同人体基质中的丙酮、乙醛、乙醇和甲醇时，也可将其用作校准标准品。
注意
容易形成三聚乙醛

Acetaldehyde, the toxic product of ethanol metabolism in the liver, covalently binds to a variety of proteins, thereby altering liver function and structure. Through its binding to tubulin, acetaldehyde decreases the polymerization of microtubules thereby impairing protein secretion and favouring

The mechanism for the thermal decomposition of acetaldehyde has been revisited with an analysis of literature kinetics experiments using theoretical kinetics. The present modeling study was motivated by recent observations, with very sensitive diagnostics, of some unexpected products in high

羟醛缩合反应是由Charles Wurtz推出的有机反应，他于1872年首次从乙醛中制备了β-羟基醛。
The aldol condensation reaction is an organic reaction introduced by Charles Wurtz, who first prepared the β-hydroxy aldehyde from acetaldehdye in 1872.
