Acetic acid (sitk) is a colorless liquid organic compound with the chemical formula CH3COOH. It is also known as ethanoic acid (nok) (also written as CH3CO2H, C2H4O2, or HC2H3O2). Apart from water, vinegar contains no less than 4% acetic acid by volume, rendering acetic acid the most important ingredient.
The second most basic carboxylic acid is acetic acid (after formic acid). It’s a popular chemical reagent and industrial chemical that’s used to make cellulose acetate for photographic film, polyvinyl acetate for wood glue, and synthetic fibers and fabrics, among other things. Dilutions of acetic acid are commonly used as descaling agents in homes. Acetic acid is a food additive with the code E260 that is used as an acidity regulator and a condiment in the food industry. The acetyl group, which is derived from acetic acid, is essential to all types of life in biochemistry. It is important for the metabolism of carbohydrates and fats when bound to coenzyme A.
The global demand for acetic acid is about 6.5 million metric tons per year (Mt/a), of which 1.5 Mt/a is fulfilled through recycling and the rest is made from methanol.
[eight] Vinegar is often dilute acetic acid, which is mostly made by fermenting ethanol and then oxidizing it.

It’s used to make cellulose acetate for photographic film, polyvinyl acetate for wood glue, and synthetic fibers and fabrics, among other things. It’s used as table vinegar, as a preservative, and as a chemical intermediate. It’s good for getting rid of glazed ceramics.

Keep a safe distance from heat, sparks, open flames, and hot surfaces. – There will be no smoking allowed. Wear protective gloves, clothing, eyewear, and face protection. IF YOU’VE SWALLOWED IT, RINSE YOUR MOUTH. Do not force yourself to vomit. IF ON SKIN (OR HAIR): Remove/Take Off ALL Dirty CLOTHES IMMEDIATELY. Rinse the skin with water or in the tub. IF IN EYES, RINSE WITH WATER CAREFULLY FOR A COUNT OF MINUTES. If contact lenses are present and simple to remove, do so. Rinse once more. Call a POISON CENTER or a doctor/physician right away.

Acetic acid uses
Acetic acid, also known as ethanoic acid, is an organic chemical compound responsible for the bitter taste and pungent odor of vinegar. Glacial acetic acid (pure water-free acetic acid) is a colorless hygroscopic liquid that freezes to a colourless crystalline solid below 16.7 °C (62 °F). While it is a weak acid due to its ability to dissociate in aqueous solutions, acetic acid is corrosive and its vapour is toxic to the eyes and nose. One of the most basic carboxylic acids is acetic acid (the second-simplest, next to formic acid). It is an effective chemical reagent and industrial chemical that is used to make polyethylene terephthalate, which is primarily used in soft drink bottles; cellulose acetate, which is primarily used in photographic film; and polyvinyl acetate, which is primarily used in wood glue, as well as many synthetic fibres and fabrics. Dilutions of acetic acid are commonly used as descaling agents in homes. Acetic acid is used as an acidity regulator in the food industry under the food additive code E260. The global demand for acetic acid is about 6.5 million tonnes per year (Mt/a), with around 1.5 Mt/a being fulfilled by recycling and the rest coming from petrochemical feedstocks or biological sources.
