Acetic acid wholesalers on the market

Acetic acid is a carboxylic acid and is known as ethanoic acid in the name IOPAC. This acid has a chemical formula and tastes sour in vinegar, similar to vinegar. This acid is a weak acid because it is only a small amount of acid isolated in aqueous solution. Pure anhydrous acetic acid (icy acetic acid) is a colorless liquid that absorbs water from its surroundings (hygroscopically) and freezes at 16.5 C (62 F) as a colorless crystalline solid. Pure acid and its concentrated solutions are highly corrosive. Acetic acid is one of the simplest carboxylic acids. This acid is an important chemical reagent and is an industrial chemical used in the production of the following materials: Polyethylene terephthalate, which is mainly used in soft drink bottles; Cellulose acetate, which is mainly used in photographic film; Polyvinyl acetate for wood glue plus fibers and synthetic fabrics. At home, dilute acetic acid is used to open pipes. In the food industry, acetic acid under the additive code E260 is used as a regulating acid and as a seasoning.

What is acetic acid used for?

Global demand for acetic acid is about 6.5 million tons (metric tons per year in Mt / a), of which about 1.5 Mt / a is met through recycling. The rest is produced by the petrochemical feed market or biological resources. The dilute acetic acid produced by natural fermentation is called vinegar. Vinegar yeast bacteria are known for their tendency to produce acetic acid. These bacteria are found in food, water and soil. Acetic acid is naturally produced from fruits and some spoiled foods from the fermentation process and is one of the oldest known chemical compounds in humans.

; The acidic strength of the hydrogen atom (H) in the carboxyl group (OOCOOH) in carboxylic acids such as acetic acid, can be released as an H + ion (proton) and give them acidic properties. Acetic acid in aqueous solutions is an effective monoproteonic acid with a constant acid dissociation value (pKa) of 0.1 A 4.8; The pH of the solution molarity (about the consistency of house vinegar) is 2.4, indicating that 0.4% of the acetic acid molecules are separated.

Acetic acid cyclic dimer; The dashed lines indicate hydrogen bonds

The crystalline structure of acetic acid indicates that the molecules are dimerically coupled together by hydrogen bonds. Dimers can be detected in steam at 120 ° C. This condition can also occur in the liquid phase of pure acetic acid, but in the presence of water, it disintegrates rapidly. Other lower carboxylic acids also have this dimerization behavior.

Liquid acetic acid, like water and ethanol, is a hydrophilic protonated solvent (polar molecule | polar). With a dielectric constant of 2.6, it can, in addition to dissolving polar compounds such as mineral salts and sugars, dissolve non-polar compounds such as oils and chemical elements such as sulfur and iodine. It mixes with many polar and non-polar solvents such as water, chloroform and hexane. This solubility and miscibility of acetic acid has made it a widely used industrial chemical.

Bulk selling of Acetic acid on the market

Acetic acid is corrosive to many metals, including iron, magnesium, and zinc, and reacts with them to produce hydrogen gas and metal salts called acetates. When aluminum is exposed to oxygen, a thin layer of aluminum oxide forms on its surface that is relatively resistant. As a result, aluminum tankers are used to transport acetic acid. Metal acetates can also be obtained by the reaction of acetic acid with a base; A well-known example of this is the “baking soda = vinegar” reaction. With the exception of chromium 2 acetate, almost all acetates are soluble in water. For more information about acetic acid price and Bulk selling of Acetic acid on the market, you can visit our site.
