Anhydrous ethanol is a colorless, transparent liquid with a characteristic pungent odor at room temperature and atmospheric pressure. It is volatile, flammable, and miscible with water as well as most organic solvents. As a key raw material and extractant in the pharmaceutical industry, it serves as the core component of fuel ethanol and is also an essential solvent in fine chemicals, electronic cleaning, and daily chemical product manufacturing. Additionally, anhydrous ethanol demonstrates broad application potential and significant value in scientific research, new energy materials, and high‑tech industries.
