What is Acrylates
Acrylates result from the esterification of acrylic acids. They are commonly known as propenoates. Vinyl groups are present in acrylates, where two carbon atoms are double bonded to each other. Acrylates are the found in polymer plastics that form the acrylate polymers. Common acrylates are methyl acrylate and ethyl acrylate.
Advantages of Acrylates
Active chemical properties
Acrylates are active chemically and are prone to reactions such as addition, polymerization, and transesterification. They can be used as precursors for many chemical reactions and used to synthesize a variety of compounds.
Fast curing
Acrylate adhesives are different from other polymer types in that they can cure quickly under ultraviolet and/or visible light. Compared with heat-curing adhesives, their main advantage is that they can bond heat-sensitive electronic devices within 5 to 30 seconds at room temperature.
Strong bonding ability
Acrylates are a non-surfactant suspending agent with antistatic, film-forming, and bonding abilities. They are often used as adhesives for artificial nails and eyelashes, and to help shape artificial nails with natural nail plates.
Acrylate production process and manufacturing process
Production process
Acrylates are industrially prepared by treating acrylic acid with the corresponding alcohol in presence of a catalyst. The reaction with lower alcohols (methanol, ethanol) takes place at 100–120 °C with acidic heterogeneous catalysts (cation exchanger). The reaction of higher alcohols (n-butanol, 2-ethylhexanol) is catalysed with sulfuric acid in homogeneous phase.
Esterification reaction
Acrylic acid is reacted with corresponding alcohols (such as methanol, ethanol, butanol, etc.) to produce acrylic acid esters. In this process, acidic catalysts are often used to promote the reaction, such as sulfuric acid, p-toluenesulfonic acid, etc., which can effectively increase the reaction rate.
Distillation separation
The acrylic acid separation tower is used for distillation separation to separate the mixture of acrylic acid ester, butanol and water from the mixture produced by the esterification reaction. This distillation separation can separate the generated butyl acrylate from the unreacted acrylic acid, thereby improving the purity of the product.
Water reflux circulation
In this process, a high proportion of the aqueous phase distillate (about 97%) is recycled to the top of the acrylic acid separation tower, forming a high water reflux ratio (about 32:1). This water reflux helps to maintain a certain operating temperature and concentration gradient in the tower, promoting the efficiency of the separation process.
Applications of Acrylates
Production of coatings
Acrylates serve as reactive building block in producing coatings and inks, adhesives, sealants, textiles, elastomers, and plastics.
Adhesives
Methyl acrylate, a type of acrylate, is used for construction of adhesives, serve as chemical intermediates, textiles and adhesives coatings, production of leather finishes like nubuck and suede, manufacture of different kinds of plastics, manufacture of textiles, and is used for water treatment.
Chemical synthesis
Ethyl acrylate has a crucial role in chemical syntheses because it easily combines with other organic and inorganic compounds in addition reactions.

Precautions for use
Storage requirements
Acrylates should not be stored at temperatures above 35ºC. Drums should be placed indoors, away from direct sunlight and direct contact with heat sources. For long-term storage (more than four weeks), it is recommended to supplement dissolved oxygen and use stainless steel or aluminum tanks and pipes.
Safety measures
When storing acrylates, the regulations for the storage of flammable liquids must be followed, including ventilated tanks equipped with flame arresters and explosion-proof electrical equipment. All pumps, tanks and pipes must be grounded.
Protective equipment
In areas where acrylates may be released, goggles, masks, neoprene gloves and rubber boots should be worn. In the event of a large leak or release, a chemical protective suit with a self-contained breathing apparatus is recommended.
How to pack and ship
Packaging
Acrylic acid is usually packaged in UV-impermeable polyethylene-lined steel drums or self-supporting high-density polyethylene drums. The packaging must be clearly marked with dangerous goods labels such as "flammable liquid" and "corrosive substances".
Transportation
Acrylic acid is transported in specially equipped rail cars or tank cars. The loading capacity of the transport container can reach 94% of its capacity. The transport vehicle should be equipped with necessary emergency equipment, such as fire extinguishers, protective gloves, masks, etc
