Sell acetic acid chemicals,
Acetic acid, ethanoic acid or vinegar [10] are organic acid chemical compounds known as acid flavorers and aromas in foods. Vinegar acids have the C2H4O2 empirical formula. This formula is often written in the form of CH3-COOH, CH3COOH, or CH3CO2H. The concentrated acetic acid (called glacial acetic acid) is a colorless hygroscopic fluid, and has a freezing point of 16.7 ° C. Vinegar contains 3-9% by volume of acetic acid, making acetic acid a major component of vinegar other than water. Acetic acid tastes sour and smelly. In addition to being produced for vinegar household consumption, acetic acid is also produced as a precursor for polyvinyl acetate and cellulose acetate. Although classified as a weak acid, concentrated acetic acid is corrosive and can invade the skin.
Acetic acid is used in the production of polymers such as polyethylene terephthalate, cellulose acetate, and polyvinyl acetate, as well as various fibers and fabrics.
Acidity regulator in the food industry
Water softeners in the household
Functional drinks eg: apple vinegar
As raw material for the manufacture of other chemicals Vinyl acetate, Cellulose acetate, Acetate Anhydrite, Esther Acetate, Acetic Salt
Acetic acid has several names such as ethanoic acid, vinegar (containing at least 4 grams of acetic acid per 100 solutions), or vinegar. Acetic acid is an organic compound containing carboxylic acid groups. The molecular formula of acetic acid is C2H4O2. This formula is often written in the form of CH3-COOH, CH3COOH, or CH3CO2H. Acetic acid has properties such as (Perry, 1999):
- Molecular weight 60.05
- Form of clear liquid (colorless)
- Typical smelling
- Easily soluble in water, alcohol, and ether
- Acetic acid solution in water is a weak acid (corrosive)
- Water-free acetic acid forms ice-like crystals at 16.7 ° C, just below room temperature
- Has a boiling point of 118.1 ° C
- Has a freezing point of 16.7 oC
- Specific graphity 1,049
