Acetic acid physical properties of the relative density (water = 1): 1.050 relative molecular weight: 60.05 freezing point (℃): 16.7 Boiling point (℃): 118.3 Viscosity (mPa.s): 1.22 (20 ℃) ??20 ℃ vapor pressure (KPa): 1.5 Appearance and Odor: colorless liquid with a pungent vinegar. Solubility: soluble in water, alcohol, ether, carbon tetrachloride and glycerol and other organic solvents. Compatibility: Material: diluted strong corrosive to metal, 316 # and 318 # stainless steel and aluminum can be used for good structural material. National product standards: GB / T 676-2007 acetic acid at room temperature is a colorless liquid strong pungent sour. Acetic acid melting at 16.6 ℃ (289.6 K). Boiling point 117.9 ℃ (391.2 K). The relative density of 1.05, a flash point of 39 ℃, explosion limit of 4% to 17% (by volume). Pure acetic acid at temperatures below the melting point will freeze into ice crystals, it is acetic anhydride, also known as glacial acetic acid. Acid soluble in water and ethanol, the solution was acidic. Acetates are soluble in water, aqueous solution is alkaline. Dimer acid dimer, dashed lines show the crystal structure of the hydrogen bond acid Zhengzhou where to buy glacial acetic acid molecules through hydrogen bonding between dimers (also known as the second conclusion was) wholesale glacial acetic acid, dimer there 120 ℃ in the vapor state. Dimers have a high stability of glacial acetic acid, now determine the molecular weight by freezing point depression method and X-ray diffraction proved that small molecular weight carboxylic acids such as formic acid, acetic acid in solid and liquid, or gaseous form dimers. When the acetic acid and water-soluble and when hydrogen bond between dimers will soon break. Other acids have similar dimerization phenomenon. (Both ends of the connection H) solvent liquid acetic acid is a hydrophilic (polar) protonated solvent, similar to ethanol and water. Because a dielectric constant of 6.2, which is not only capable of dissolving polar compounds, such as salts and sugar, but also non-polar compound can be dissolved in glacial acetic acid production, such as oil or some elements of the molecule, such as sulfur and iodine. It also can be mixed with many polar and non-polar solvents, such as water, chloroform, hexane. Solubility and miscibility of acetic acid makes it a widely used chemical in chemicals.
