Acrylic Acid (AA)

Acrylic Acid Glacial (AA) is an unsaturated monocarboxylic acid. It reacts as a vinyl compound and as a carboxylic acid. It readily undergoes polymerization and addition reactions. It can be used as a carboxylic acid to produce acrylic esters, acrylamide, N-substituted acrylamides and acrylyl chloride by common methods. Copolymers can be produced with acrylic and methacrylic esters, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, and ethylene. Homopolymers of acrylic acid and copolymers which contain a preponderance of acrylic acid have a glassy consistency and are frequently soluble in water. They can be used in the form of their free acids and ammonium and alkali salts in many different applications, such as thickeners, dispersing agents, flocculants, protective colloids for stabilizing emulsions and polymer dispersions, wetting agents, coatings and textile finishes. 

Acrylic Acid Glacial (AA) readily undergoes addition reactions with a wide variety of organic and inorganic compounds. This makes it a very useful feedstock for the production of many low molecular compounds. For instance, acrylic acid can be used to produce derivatives of propionic acid with water, alcohols, amines, halogens and chlorinated hydrocarbons. It can also be used with other substances to produce unsaturated fatty acids, heterocyclic compounds, and Diels-Alder addition products. 

Acrylic Acid Glacial (AA) polymerizes very readily. It is generally stabilized with 200 ppm of hydroquinone monomethyl ether (MEHQ). It is only ever supplied in its stabilized form because it can polymerize with explosive violence if it is not stabilized. It is not usually necessary to remove the stabilizer because its action can be compensated for by adding an excess of the initiator.

In order to prevent polymerization Acrylic Acid must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. Glacial Acrylic Acid must be stored between 15 and 25 °C. For extended storage periods over 4 weeks, it is advisable to replenish the dissolved oxygen content. Under these conditions, the storage stability of one year can be expected. In order to minimize the likelihood of over storage, the storing procedure should strictly follow the “first-in-first-out” principle. To prevent freezing, the temperature of acrylic acid should never drop below 15 °C. Improper thawing can result in violent polymerization. Do not attempt to thaw frozen or partially frozen acrylic acid unless you have received prior approval from your supplier. It is highly recommended that emergency restabilization systems is installed. This may help to prevent polymerization of the material in a situation of pool fire, contamination or other unforeseeable events although it is no substitute for appropriate preventive measures.
