Details

acetic acid, also known as acetic acid (36% - 36%), glacial acetic acid (98%), chemical formula ch3cooh, is a kind of organic acid, a yuan for acid in vinegar and irritating odor source.pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid, freezing point is 16.6 ℃ (62 ℉), colorless crystals after solidification.although according to the dissociation ability of acetic acid in aqueous solution it is a kind of weak acid, acetic acid is corrosive, however, the steam eyes and nose stimulating role.

description of compound

acetic acid, also known as acetic acid, glacial acetic acid, chemical type ch3cooh, is an organic monogenic acid and short chain saturated fatty acid, which is the source of sour and pungent smell in vinegar.pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid, freezing point is 16.7 ℃ (62 ℉), colorless crystals after solidification.although acetic acid is a weak acid according to its dissociation capacity in aqueous solution, acetic acid is corrosive and its vapors irritate eyes and nose.

acetic acid is a simple carboxylic acid, which is composed of a methyl group and a carboxyl group, and is an important chemical reagent.in the chemical industry, it is used to make polyethylene terephthalate, the main part of a beverage bottle.acetic acid is also used to make cellulosic acetate and polyvinyl acetate in wood adhesives required for film, as well as many synthetic fibres and fabrics.in families, dilute acetic acid solution is often used as descaling agent.in the food industry, acetic acid is a prescribed acidity regulator in the food additive list e260.

worldwide demand for acetic acid is around 6.5 million tons per year.about 1.5 million tons are recycled, and the remaining 5 million tons are made directly from petrochemical materials or through biological fermentation.

ethanoic acid is both a commonly used name and the official name prescribed by the international federation of pure and applied chemistry (iupac).commonly known as acetic acid, the name comes from the latin word acetum for vinegar.anhydrous acetic acid in slightly lower than at room temperature (16.7 ℃), can be converted into a kind of corrosive ice crystals, reason often called hardly aqueous acetic acid glacial acetic acid (glacial acetic acid).

production methods

1. acetic acid is widely distributed in nature.in fruit or vegetable oils, for example, it is mainly in the form of esters.free acid is present in the tissues, excreta and blood of animals.many microbes can turn different organisms into acetic acid by fermentation.there is a record of vinegar production in ancient china. as early as before bc, people could make vinegar by oxidative fermentation of various acetic acid bacteria. in the late 19th century, it was found that acetic acid could be obtained by dry distillation of wood.in 1911, the world's first industrial device for acetaldehyde oxidation production of acetic acid was built in germany.the method of producing acetic acid by oxidation of low carbon hydrocarbon was developed.in 1960, the former federal republic of germany adopted the method of carbonylation of methanol under high pressure (20mpa) to produce acetic acid.subsequently, monsanto company adopted rhodium complex catalyst (iodide was used as co-catalyst) to reduce the pressure of methanol carbonylation to 0.3-3.0mpa, and built the methanol low-pressure carbonylation industrial device with the production capacity of 135kt acetic acid in 1970.due to its advanced technology and economy, the low pressure carbonylation of methanol has been used in many large factories since the mid-1970s.in 1984, the annual production capacity of acetic acid in the world reached 6mt, and the low pressure carbonylation method accounted for about 40%.

1. the fermentation using starch fermentation liquid (including 3-6% ethanol), under the action of vinegar mother of bacteria, fermentation in around 35 ℃, light liquid oxidation by air into vinegar.vinegar contains organic acids, esters and proteins in addition to 3-6% acetic acid.fermentation is mainly used to make vinegar.

it is the main method of producing acetic acid in industry....

use

acetic acid, also known as acetic acid, is widely found in nature. it is an organic compound and is a typical fatty acid.it is recognized as the source of sour and pungent smell in vinegar.in families, dilute acetic acid solution is often used as descaling agent.food industry, on the food additives list.
