Technical Informations

Application Advice/Typical Applications

There are two reaction centers in acrylic acid molecule for possible reactions – the double bond and the carboxylic group. It readily undergoes polymerization and addition reactions on the unsaturated group. And it reacts on the carboxylic group forming esters, amides etc.

Copolymers can be produced with acrylic esters, methacrylates, styrene, acrylonitrile, vinyl acetate, vinyl chloride, butadiene, ethylene etc. Homopolymers and polar copolymers are frequently soluble in water. They can be used in the form of acid or salts in many applications, such as thickeners, dispersing agents, flocculants, wetting agents, superabsorbents etc. Water or solvent dispersion of polymers are used in coatings, adhesives, textile or paper industry etc. Acrylic acid is a very important raw material for manufacturing of many propionic acid derivatives or specialty monomers used in a great variety of chemical processes and technologies.





Shipping and Storage

Acrylic acid is transported in specially equipped railway cars or tanker trucks.
Transport containers are filled to a maximum of 94 % of their capacity.


In order to prevent spontaneous polymerization, acrylic acid must always be stored under air, never under inert gases.The air (oxygen) presence is required for proper functionality of the stabilizer. Product storage temperature must be between 15 and 25 °C.

Under these conditions, a storage stability of one year can be expected. It is advisable to minimize the likelihood of acrylic acid overstorage by a strict observance of the“first-in-first-out” storage principle. For storage periods extended over 4 weeks, it is advisable to replenish the dissolved oxygen content in the product by suitable aeration.
Dimer of acrylic acid is formed during storage and this process is inevitable and cannot be prevented. The dimer formation is promoted solely by higher storage temperature and storage period.
The contained dimer of acrylic acid could affect acrylic acid reactivity and performance in some processes.
It is necessary to prevent freezing of acrylic acid, therefore the acrylic acid temperature should never drop under 15 °C.  Unsuitable thawing of solidified acrylic could lead to a spontaneous and dangerous polymerization accompanied by a massive heat release or even an explosion. Do not thaw frozen acrylic acid without consultation and approval from your supplier.
Under no circumstances should steam be used to heat or thaw acrylic acid.

Stainless steel is the recommended material for storage tanks and piping. Avoid contamination with alloys containing copper or silver.
All metal made equipment (tanks, pumps, piping etc.) must be earthed. All national laws and directives, as well as local regulations governing storage, handling, distribution and disposal of flammable liquids must be strictly observed. Avoid exposure to high temperatures, sparks, flame, light and frost. Keep separated from oxidizing materials. Keep the container tightly closed.
