Ethanol can be miscible with water in any ratio, and can be miscible with chloroform, ether, methanol, acetone and most other organic solvents. Ethanol can be used to manufacture acetic acid, beverages, essence, dyes, fuels, etc. In medicine, ethanol with a volume fraction of 70%-75% is commonly used as a disinfectant.
