如果物质相互溶解形成均匀的溶液，就可以说它们相互混溶。收藏或下载我们的常见实验室溶剂混溶性表。
Substances are said to be miscible in one another if they dissolve to form a uniform solution. Bookmark or download our miscibility table for common lab solvents.
Preformed catalysts in the kit are stable but become air-sensitive when activated; Schlenk technique aids scale-up.
