Uses

Acetic Acid is an acid produced chemically from the conversion of alcohol to acetaldehyde to acetic acid. it is the principal component of vinegar which contains not less than 4 g of acetic acid in 100 cm3 at 20°c. the approved salts include sodium acetate, calcium acetate, sodium diacetate, and calcium diacetate. it is used as a preservative, acidulant, and flavoring agent in catsup, mayonnaise, and pickles. it can be used in conjunction with leavening agents to release carbon dioxide from sodium bicarbonate.

Uses

Used in the manufacture of vinyl acetate monomer (VAM), this accounts for one-third of acetic acid consumption. As a food additive (condiment, ingredient) or as a preservative, it is found in Vinegar solutions, usually between 3-9% in concentration. In the production of various synthetic materials, acetic acid is a precursor and solvent for various glues and plastics such as polyvinyl acetate, cellulose acetate, nylon and dimethyl terephthalate. As an agent widely used in the manufacture of organic compounds which are constituent parts of food ingredients, various dye stuffs and perfumes, Rayon fibre, synthetic fibres and textiles, inks and dyes, soft drinks bottles, rubbers and plactics, and pesticides. In waste water treatment, acetic acid may be dosed to correct highly alkaline pH from where caustic soda has been dosed to the fluid stream. For testing blood in clinical laboratory For the treatment of outer ear infections from the growth of fungus and bacteria

Solidifying fixatives

Acetic acid is a colorless and transparent liquid, being highly irritating. It is condensed into ice in cold condition, thus being also known as glacial acetic acid. Acetic acid can be formulated into solutions of various ratios using water and alcohol; the concentration ranges from 0.2 to 5%; it is often used together with other fixatives. It has strong penetration capability with single use causing protoplasm expansion, thus often being used in combination with alcohol, formaldehyde. Acetic acid is an excellent fixative of chromosomes, so the fixing solutions of chromosomes almost all contain acetic acid. Features: strong penetration capability; can cause tissue expansion.

Taboo

Allergic patients and patients of otitis media perforation should be disabled.

Uses

Colorless liquid prepared by the distillation of wood or the oxidation of dilute ethyl alcohol. Acetic acid has a very pungent smell, and the vapors are flammable. When obtained in full strength (99 percent), it congeals as an ice-like solid at 16.7°C. For this reason the term glacial is also used to describe this acid. It is soluble in water, alcohol, ether, chloroform, and gelatin. Acetic acid was used as a restrainer for the physical development of calotypes, Niépceotypes, and collodion plates. Photographers also used it to retard non-image reduction of these processes by adding it to the silver nitrate solution. Acetic acid is used as a stop bath and as a solvent for gelatin.

Biotechnological Production

Acetic acid is produced for beverage, food, and feed applications almost entirely using the traditional vinegar process . First, ethanol is produced by fermentation with Saccharomyces cerevisiae in the absence of oxygen. Then, acetic acid is generated from ethanol by acetic acid bacteria, such as Acetobacter aceti, Acetobacter pasteurianus, or Gluconacetobacter europaeus, under aerobic conditions. Different substrates, such as malt, fruits, and sugarcane, are used for vinegar production . Today, processes with two stages (e.g. two-tank cycle fermentation or two-stage submerged fermentation) are generally employed on an industrial scale. In a first step, biomass is produced in parallel to the acetic acid production. In the second part of the process, mainly acidification takes place. Acetic acid concentrations up to 200 g.L-1 can be achieved . The vinegar process has been well studied over many decades . However, there are still attempts to enhance vinegar production, especially regarding productivity and cost minimization through alternative substrates, new process concepts (e.g. immobilized cells or mixed cultures of yeasts and acetic acid bacteria, and optimized acetic acid bacteria. Acetic acid can be produced under anaerobic conditions by some microorganisms such as Clostridium thermoaceticum . In free-cell batch fermentations, acetate concentrations of 50 g.L-1 were reached in less than 192 h. Acetic acid concentrations of 83–100 g.L-1, a yield of 0.74–0.80 g acetic acid per gram glucose, and a productivity of 0.60–0.85 g.L-1.h-1 were observed under optimized conditions in a cell-recovered fed-batch process with pH-control using glucose as substrate.

Synthetic route

Alcohol oxidation: 95% of the raw alcohol and 76% of the alcohol recovered in the workshop are mixed in the mixing tank ratio into 84 ± 0.5% dilute alcohol, the alcohol ingredient is heated by evaporation pot into the oxidation furnace, and has reaction to generate acetaldehyde gas at 555 ± 5 ℃ high temperature and under the catalysis of electrolytic silver. The reaction gas mixture enters into the absorption tower after being condensed, and is diluted with about 8-10% of dilute acetaldehyde after being absorbed by water once. Acetaldehyde refining and alcohol recovery: dilute acetaldehyde is sent into the acetaldehyde distillation column for pressure distillation; control the top temperature at 45 ± 2 ℃ and pressure at 0.15Mpa; the tower gives pure acetaldehyde. Bottoms temperature should be controlled at 121 ± 3 ° C, the material is pressurized into the alcohol recovery column distillation with the tower temperature being controlled at 90 ± 5 ° C; the tower top finally produce about 76% alcohol to be used as the ingredient of the alcohol oxidation process; control the bottoms temperature at 110 ± 3 ℃, and the waste water is discharged through the tower kettle. Acetaldehyde oxidation: Acetaldehyde enters into the oxidation tower through the action of the pressure pump; it has reaction with the compressed air at a temperature of 50 ~ 80 ℃, pressure 0.20 ~ 0.22Mpa and under a certain amount of manganese acetate to generate crude acetic acid. The crude acetic acid is discharged from the upper discharge port of the oxidation tower to the crude acetic acid storage tank; the unreacted acetaldehyde is condensed and separated from the top of the tower through the condenser, the liquid is refluxed to the bottom of the oxidation tower, and the exhaust gas is further absorbed into the rear of the oxidation tower by the bubbling absorber into the atmosphere. Acetic acid refinement: The crude acetic acid is evaporated by the high-boiling pot to separate the manganese acetate from the heavy component, the temperature of the high-boiling evaporation pot is controlled at 120 ± 2 ℃, and the manganese acetate at the bottom of the high-boiling pot is discharged into the manganese circulation tank of the acetaldehyde oxidation process for recycling. The light fraction in the top enters into the concentration distillation column, and the bottoms temperature is controlled at 123 ± 3 ° C; acetic acid inside the tower is continuously and quantitatively discharged into the finished product evaporating pot and further distilled and condensed into acetate at 120 ± 2 ℃ into the finished product metering tank. After qualification, it is sent into the finished product pot. The temperature of the top of the tower is controlled at 100 ± 2 ℃. The dilute acid produced at the top of the tower enters into the measuring tank and is put into the dilute acid tank after measurement. Production route includes BP Cativa process and Celaness AOPlus process. BP Cativa process BP is the world's largest provider of acetic acid, and 70% of the world's acetic acid production uses BP technology. BP introduced the Cativa technology patent in 1996. The Cativa process uses a new iridium-based catalyst system and uses a variety of new additives such as rhenium, ruthenium and osmium. The iridium catalyst system has higher activity than rhodium catalysts with few by-products and operates at lower water concentrations (less than 5%), which greatly improves traditional methanol carbonylation, cuts production costs by up to 30%, and reduces expansion costs by 50%. In addition, due to the decrease of water concentration, the CO utilization efficiency is increased and the steam consumption is reduced. Celanese AOPlus process Celanese is also one of the largest acetic acid producers in the world. In 1978, the Hurst-Celanese Company (now Celanese) commissioned a Monsanto acetic acid plant at Lake Clare in the U.S. state of Texas. In 1980, Celanese Corporation introduced the AOPlus method (acid optimization method) technology patents, greatly improving the Monsanto process. The AOPlus process increases the rhodium catalyst stability by adding high concentrations of inorganic iodine (mainly lithium iodide), and the water concentration in the reactor after the addition of lithium iodide and methyl iodide.

Background and overview

An important chemical product. Colorless; irritating odor and sour corrosive liquids. More than 1000 BC, humans had begun to use acetate bacteria for wine fermentation to make vinegar. Vinegar has a acetic acid content of 2% to 12%. In 1911, Germany used acetaldehyde oxidation method to create the world's first synthetic acetic acid plant. In 1966 Monsanto, the United States developed the methanol low-pressure carbonylation process (built in 1970), which has become the main method of synthesizing acetic acid, accounting for more than 50% of the total output. In 1999, the world's acetic acid production was about 5 million tons. China began producing acetic acid in the 1950s, producing about 60,000 tons in the 1960s and increasing to 861,300 tons in 2001. The vast majority of acetic acid has been converted into derivatives for application. 40% to 50% has been used for the production of vinyl acetate in China and the United States. Both acetate ester and cellulose acetate accounts for 10% to 12%; solvent application accounts for 20% to 25%.
