Tepkiler ve kullanımlar
Akrilik asit, bir karboksilik asidin tipik reaksiyonlarından geçer. Bir alkol ile reaksiyona girdiğinde, ilgili esteri oluşturur. Akrilik asidin esterleri ve tuzları topluca akrilatlar (veya propenoatlar) olarak bilinir. Akrilik asidin en yaygın alkil esterleri metil, butil, etil ve 2-etilheksil akrilattır.
Akrilik asit ve esterleri, kendi aralarında (poliakrilik asit oluşturmak için) veya diğer monomerlerle (örneğin akrilamidler, akrilonitril, vinil bileşikler, stiren ve bütadien) çift bağlarında reaksiyona girerek, imalatta kullanılan homopolimerler veya kopolimerler oluşturarak kolayca birleşir. çeşitli plastiklerin, kaplamaların, yapıştırıcıların, elastomerlerin yanı sıra zemin cilaları ve boyaları.
Akrilik asit, çocuk bezi endüstrisi, su arıtma endüstrisi veya tekstil endüstrisi gibi birçok endüstride kullanılan bir bileşiktir. Dünya ölçeğinde akrilik asit tüketim oranının 2020 yılına kadar tahmini 8.000 kilo tonun üzerine çıkacağı tahmin edilmektedir.

Acrylic acid (IUPAC: propenoic acid) is an organic compound with the formula CH2=CHCOOH. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly
to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. It is miscible with water, alcohols, ethers, and chloroform. More than a million tons
are produced annually.
Acrylic acid
Product
Acrylic acid is a colorless liquid above its freezing point of +13°C ( +56°F). It is fully miscible in water at +20°C (+68°F).
Acrylic acid will polymerize to form homopolymers and can be copolymerized with their esters and other vinyl monomers. Its carboxylic acid functionality provides anionic character and reactivity with alcohols and epoxides.

Acrylic acid (GAA) is made by the direct oxidation of propylene. It is a raw material for various esters, super absorbent polymers (SAP), dispersants, flocculants, thickening agents, and adhesives.
EINECS: No. 201-177-9
History
The word "acrylic" was coined in 1843, for a chemical derivative of acrolein, an acrid-smelling oil derived from glycerol.
Production
Acrylic acid is produced by oxidation of propylene, which is a byproduct of the production of ethylene and gasoline:
CH2=CHCH3 + 3⁄2 O2 → CH2=CHCO2H + H2O
Historical methods
Because acrylic acid and its esters have long been valued commercially, many other methods have been developed. Most have been abandoned for economic or environmental reasons. An early method was the hydrocarboxylation of acetylene ("Reppe chemistry"):
Acrylic acid synthesis from acethylene.png
This method requires nickel carbonyl, high pressures of carbon monoxide, and acetylene, which is relatively expensive compared to propylene.
Acrylic acid was once manufactured by the hydrolysis of acrylonitrile, a material derived from propene by ammoxidation, but this route was abandoned because it cogenerates ammonium side products, which must be disposed of. Other now abandoned precursors to acrylic acid include ethenone and ethylene cyanohydrin.[6]
Research
Propane is a significantly cheaper raw material than propylene, so one alternative route being explored is the one-step selective oxidation of propane.
Carboxylating ethylene to acrylic acid under supercritical carbon dioxide condition is thermodynamically possible, but efficient catalysts have not been developed. 3-Hydroxypropionic acid (3HP), an acrylic-acid precursor by dehydration, can be produced from sugars, but the process is not competitive.[9][10]
Reactions and uses
Acrylic acid undergoes the typical reactions of a carboxylic acid. When reacted with an alcohol, it forms the corresponding ester. The esters and salts of acrylic acid are collectively known as acrylates (or propenoates). The most common alkyl esters of acrylic acid are methyl, butyl, ethyl, and 2-ethylhexyl acrylate.
Acrylic acid and its esters readily combine with themselves (to form polyacrylic acid) or other monomers (e.g. acrylamides, acrylonitrile, vinyl compounds, styrene, and butadiene) by reacting at their double bond, forming homopolymers or copolymers, which are used in the manufacture of various plastics, coatings, adhesives, elastomers, as well as floor polishes and paints.
Acrylic acid is a compound, which is used in many industries like the diaper industry, the water treatment industry or the textiles industry. On a worldwide scale the consumption rate of acrylic acid is projected to reach more than an estimated 8,000 kilotons, by 2020. This increase is expected to occur as a result of using this product in new applications, including personal care products, detergents and products that are used for adult incontinence.[11]
Substituents
As a substituent acrylic acid can be found as an acyl group or a carboxyalkyl group, depending on the removal of the group from the molecule.
More specifically, these are:
The acryloyl group, with the removal of the −OH from carbon-1.
The 2-carboxyethenyl group, with the removal of a −H from carbon-3. This substituent group is found in chlorophyll.
Safety
Acrylic acid is severely irritating and corrosive to the skin and the respiratory tract. Eye contact can result in severe and irreversible injury. Low exposure will cause minimal
or no health effects, while high exposure could result in pulmonary edema. The LD50 is 340 mg/kg (rat, oral).
Acrylic acid is a constituent of tobacco smoke.
Acrylic acid, also known as 2-propenoic acid or acrylate, belongs to the class of organic compounds known as acrylic acids. These are organic compounds containing acrylic acid CH2=CHCO2H.
Acrylic acid exists as a liquid, soluble (in water), and a weakly acidic compound (based on its pKa). Acrylic acid has been primarily detected in saliva. Within the cell, acrylic acid
is primarily located in the cytoplasm. Acrylic acid participates in a number of enzymatic reactions. In particular, Acrylic acid can be biosynthesized from acrolein; which is catalyzed
by the enzymes retinal dehydrogenase 1 and aldehyde dehydrogenase, dimeric nadp-preferring. In addition, Acrylic acid can be biosynthesized from acrolein; which is catalyzed by the
enzymes retinal dehydrogenase 1 and aldehyde dehydrogenase, dimeric nadp-preferring. In humans, acrylic acid is involved in the ifosfamide metabolism pathway, the cyclophosphamide
metabolism pathway, the cyclophosphamide action pathway, and the ifosfamide action pathway. Outside of the human body, acrylic acid can be found in pineapple. This makes acrylic
acid a potential biomarker for the consumption of this food product.
Acrylic acid, [waste] appears as a colorless liquid with a distinctive acrid odor. Combustible. Flash point 130°F. Boiling point 286°F. Freezing point 121°F. Corrosive to metals and
tissue. May polymerize under prolonged exposure to fire or heat. If polymerization occurs in a container violent rupture may occur. Generally shipped with an inhibitor such as
hydroquinone to prevent polymerization.

Acrylic acid is a colorless liquid with a distinctive acrid odor. Flash point 130°F. Boiling point 286°F. Freezing point 53°F. Corrosive to metals and tissue. Prolonged exposure
to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur. The inhibitor (usually hydroquinone) greatly reduces the
tendency to polymerize.
