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 effect, glacial acetic acid, 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. Acetic acid (acetic acid) molecules containing unsaturated carboxylic acid two carbon atoms. Formula CH3COOH. Because the main component of vinegar, acetic acid manufacturer in Henan Province, also known as acetic acid is widely found in nature, such as fruit or vegetable oils mainly It exists in the form of an ester compound; in animal tissue, feces and blood in the free acid form of colorless liquid with a pungent odor melting point 16 .6 ℃, boiling point 117 .9 ℃, relative density of 1.0492 (. 20/4 ℃), refractive index 1.3716. pure acetic acid in the following 16.6 ℃ can ice-like solid, so often referred to as glacial acetic acid, soluble in water, ethanol, ether and carbon tetrachloride. When water is added acetic acid, and the total volume of mixed smaller increase in density until the molecular ratio of 1 is equivalent to the original form of a monobasic acid acid CH3C (OH) 3, further diluted, volume did not change health hazard pathways: inhalation , ingested, percutaneous absorption health hazards: after inhalation of the nose, throat and respiratory tract irritation strong eye contact with the skin irritation, light erythema, glacial acetic acid, causing severe chemical burns wrongly concentrated. acetic acid, mouth and digestive tract can produce erosion, severe shock and death may be due to chronic effects: eyelid edema, conjunctival hyperemia, chronic pharyngitis and bronchitis long-term repeated exposure can cause skin drying, degreasing and dermatitis sales of glacial acetic acid.
