Quality specification

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.Glacial acetic acid, which is anhydrous acetic acid. It is a carboxylic acid, belongs to the weak acid class, is connected by a hydrocarbon group and a carboxylic group, its molecular expression is C2H4O2. However, due to the high acetic acid content in glacial acetic acid, generally more than 95%, its volatile acid accounts for a significant proportion, so it shows strong volatility. Glacial acetic acid is an important chemical raw material, widely used in medicine, organic chemical industry, organic synthesis, synthetic fiber, polymer chemical industry, pesticide, leather, rubber and other industries. Glacial acetic acid is one of the most important organic acids. It is mainly used in the synthesis of monochloroacetic acid, vinyl acetate, amino acid and so on. Glacial acetic acid as a fine chemical product. In the pharmaceutical industry, food industry and other industries also have a broad market. Glacial acetic acid as a chemical reagent is one of the common varieties.
