Precautionary statements - describe recommended measures to minimise or prevent adverse effects resulting from exposure to a hazardous product or improper storage or handling of a hazardous product. It is considered as a replacement for terathydofuran in organic synthesis due to its less water and peroxide and high boiling point. Liquid dibutyl ether is lighter than water. Often, it's called heteroatoms, when carbon is replaced by an oxygen or any atom other than carbon or hydrogen. This colorless liquid has a sweet, ether -like odor, as it derives from the family of glycol ethers, and is a butyl ether of ethylene glycol. The described Product category (i.e. More information about the EC Inventory can be found here. In that case, the ATP (Adaptation to Technical Progress) number is displayed.
