Factory Price Glacial Acetic Acid 99.99% Gaa for Industrial Grade CAS 64-19-7 CH3COOH in large stock

1. Description :
2. 
   
3. Acetic acid, chemical formula CH3COOH, also known as acetic acid, is the simplest organic weak acid except formic acid (pKa = 4.75 at room temperature). Acetic acid is a colorless and pungent liquid at room temperature and pressure. It is often represented by the symbol HOAc or HAc and is the main component of vinegar.
   Acetic acid is widely distributed in nature, such as in the form of ethyl acetate in fruits and vegetables and vegetable oils, in the form of free acid in animal tissues, excreta and blood, and in microorganisms from other organic matter fermentation conversion.
   For anhydrous acetic acid, often referred to as "glacial acetic acid", it is a colorless hygasscopic liquid with a freezing point of 16.6 ° C (62 ° F), and becomes a colorless crystal after solidification. Its aqueous solution is weakly acidic and highly corrosive, and the steam has an irritating effect on the eyes and nose.

1. Applications:

Acetic acid is an important chemical agent and industrial chemical, mainly used in the production of cellulose acetate for photographic film, polyvinyl acetate for wood glue, and synthetic fibers and fabrics. In the home, diluted acetic acid is often used as a scale remover.

Acetic acid is an important chemical raw material. The industrialized acetic acid production technologies mainly include methanol carbonylation, acetaldehyde oxidation, ethylene direct oxidation and light oil oxidation. Among them, methanol carbonylation is the most widely used technology, accounting for more than 60% of the global total production capacity, and this trend is still growing. The global acetic acid production capacity has been showing an upward trend. In the next few years, its global demand will also increase at an average annual rate of about 5%, of which 94% of the global new acetic acid production capacity will occur in Asia, and Asia will lead the rapid growth of global market demand in the next five years.

preparation
Add potassium permanganate to industrial acetic acid and dissolve. Acetic acid is steamed in a distillation column. Add appropriate amount of chromium anhydride to dissolve, take the upper semen for distillation. The middle fraction is glacial acetic acid.

use
Commonly used analytical reagents. Universal solvents and non-aqueous titrating solvents. Used in the manufacture of acetate, cellulose acetate, medicine, pigments, esters, plastics, spices and so on.
