==性质==
无色针状可[[升华]]结晶。溶于热水、[[乙醇]]、[[乙醚]]、[[苯]]、[[氯仿]]。溶于[[浓硫酸]]呈紫色[[荧光]]。与[[高锰酸钾]]作用得[[水杨酸]]。<ref name="chemyq">{{cite web|url=http://www.chemyq.com/xz/xz6/52219xvadp.htm|title=色酮；苯并-γ-吡喃酮|publisher=化工引擎|accessdate=2009-09-04|archive-date=2021-06-14|archive-url=https://web.archive.org/web/20210614125413/http://www.chemyq.com/xz/xz6/52219xvadp.htm}}</ref> 与[[格氏试剂]]作用得4-取代苯并[[吡喃鎓盐]]。<ref>{{有机杂环化合物|pages=93}}</ref>

==制取==
由[[邻羟基苯乙酮]]与[[甲酸乙酯]]在碱存在下缩合，产物再经酸催化成环制取。<ref name="chemyq"/>

==来源==
色酮自身至今尚未从天然来源中分离得到，但衍生物广泛存在于自然界中，有些为有色物质，因此得名色酮。[[黄酮]]和[[异黄酮]]是色酮的重要衍生物。
