glacial acetic acid

Colorless clear liquid. The melting point 16.635℃, boiling point 117.9℃, relative density 1.0492 (20 / 4℃) refractive index 1.3716, flash point (open cup) 57℃, spontaneous combustion Point 465℃, viscosity 11.83mPa s (20℃). Pure acetic acid is below 16℃, it can form an ice solid, so it is called glacial acetic acid. With water, ethanol, benzene, and Ether is miscible, insoluble in carbon disulfide. When water is added to acetic acid, the total volume after mixing becomes smaller and the density increases. Molecular ratio of 1:1, further dilution, No more of the above volume changes occurred. There is a pungent odor.
