Physicochemical properties:
1.Colorless liquid and irritating dour.
2.Solubility  water, ethanol, benzene and ethyl ether immiscible, insoluble in carbon disulphide.
Storage:
1.Keep it in cool, ventilated place
2.Keep away from heat surface, sparks, open flames and other ignition sources, no smoking. In winter, keep it above 0 ℃ to prevent freezing.
3.Keep container tightly closed.must be kept separate from the oxidant and alkali.
4.Use explosion-proof [electrical/ventilating/lighting]equipment.
5.Use non-sparking tools.
6.Ground and bond container and receiving equipmen
Application
1. Instead of glacial acetic acid,it is used in dyeing and finishing pro-cesses of acrylic. dacron, nylon and other Chemical fiber,wool. silkand other animal fiber,cotton. linen. yarn and other plant fiber,Waxprinting,and blend fabric.
2. The adjustment of PH value of all kinds of acid pickling, dyeingbath (including color bath),color fixing,resin finishing etc.
3. Producing some kinds of dyestuff,such as Benzidine Yellow G.
Advantage
The function and effect are better than the other dyeing acid andglacial acetic acid.lt has no damage to the fiber,in dyeing bath pHvalue is stable.it have no acid fold,sediment and effects of hardwater,improve dye uptake and level-dyeing property of somedyestuff ,and have no effects on coloured light or color fastness ofayed products.In addition,no pungent smell, no frozen in winter, safeand easy to use.Acetic acid (also called acetic acid or glacial acetic acid) ₃ is an organic monic acid due to the sourness and pungent odor in vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.7 ° C (62 ° F). Upon solidification, it becomes a colorless crystal. Although acetic acid is a weak acid based on its ability to dissociate in aqueous solutions, acetic acid is corrosive and its vapors are irritating to the eyes and nose.

Relative density (water is 1) : 1.050

Relative molecular weight: 60.05

Freezing point (℃) : 16.6

Boiling point (℃) : 117.9

Viscosity (mPa.s) : 1.22 (20℃)

Vapor pressure at 20℃ (KPa) : 1.5

Appearance and smell: Colorless liquid, pungent vinegar smell.

Solubility: soluble in water, ethanol, ether, carbon tetrachloride and glycerol and other organic solvents.

Compatibility: Material: after dilution has strong corrosion to metal, 316# and 318# stainless steel and aluminum can be a good structural material.

National Product Standard number: GB/T 676-2007

Acetic acid at room temperature is a colorless liquid with strong pungent acid taste. The melting point of acetic acid is 16.6℃ (289.6 K). Boiling point 117.9℃ (391.2 K). The relative density is 1.05, the flash point is 39℃, and the explosion limit is 4% ~ 17% (volume). Pure acetic acid will freeze into ice crystals below the melting point, so anhydrous acetic acid is also called glacial acetic acid. Acetic acid is soluble in water and ethanol, and its aqueous solution is weakly acidic. Acetate is also easily soluble in water, and the aqueous solution is basic.
