Application:
Glacial acetic acid is one of the most important organic acids. Mainly used in vinyl acetate, acetic anhydride, cellulose acetate, acetate and metal acetic acid salt, also used as a solvent and pesticide, medicine and dye industries raw materials, in photographic drug manufacturing, fabric printing and dyeing, and has wide applications in rubber industry. Glacial acetic acid is one of important organic chemical raw materials, it is in an important position in the organic chemical industry. Acetic acid is widely used in synthetic fibers, coatings, pharmaceuticals, pesticides, food additives, dyeing and other industries, is an important part of national economy. Glacial acetic acid industrial and consumption by use is divided into two kinds, edible glacial acetic acid can be as as an acidity regulator and flavouring agent. It can produce synthetic vinegar.
Packing & Storage:
25kg,35kg,200kg/plastic drum.
It should be stored in a cool, well-ventilated and dry place, away from solarization, flame source and heat source; and should not be stored together with alkali substances. The packing container shall be clean and dry, and shall be gently handled to prevent any collision during transportation and loading/unloading.
