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 was originally produced by fermentation and wood distillation, and is now generally produced by ethanol or acetaldehyde oxidation. In recent years, butane is used as raw material by catalysis and oxidation (cobalt acetate as catalyst, air oxidation, acetic acid is a mixture containing ketones, aldehydes, alcohols, etc.).
