Fordításra előkészítve!
Ezen a lapon kiegészítő információk találhatóak az etanol szócikkhez. Hacsak nem említjük, az adatok szabványos nyomás és hőmérsékleti feltételekre vonatkoznak. A lap első része a vízmentes (anhydrous) etilalkohol adatait tartalmazza (másnéven: ethanole absolute), a szócikk végén az alkohol és a víz elegyének (aqueous solution) adatait.
The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet (MSDS ) for this chemical from a reliable source and follow its directions.
