Overview
Ethyl acrylate is an ester of acrylic acid and ethanol, widely used in industrial applications due to its reactivity and ability to form polymers. It is a key monomer in the production of acrylic resins, which are essential in coatings, adhesives, and textiles. The compound is known for its strong, acrid odor and is typically handled in controlled environments due to its flammability and toxicity. Industrial-grade ethyl acrylate must meet specific purity standards to ensure optimal performance in manufacturing processes.
Physical and Chemical Properties
Ethyl acrylate is a colorless liquid with a boiling point of 99.4°C and a melting point of -71°C. Its density is 0.923 g/cm³ at 20°C, and it is slightly soluble in water but miscible with most organic solvents. The compound is highly reactive, particularly in polymerization reactions, and can form explosive peroxides when exposed to air. It is also flammable, with a flash point of 9°C, requiring careful handling and storage to prevent accidents.
Main Applications
Ethyl acrylate is primarily used in the production of acrylic polymers and copolymers, which are integral to coatings, adhesives, and textiles. These polymers provide durability, flexibility, and resistance to environmental factors. In the textile industry, ethyl acrylate is used to create finishes that improve fabric feel and wrinkle resistance. It is also a component in plasticizers and emulsion polymers, which are used in paints and coatings for automotive and architectural applications.
Safety and Storage
Due to its toxicity and flammability, ethyl acrylate requires strict safety measures. Workers must use personal protective equipment (PPE), including gloves, goggles, and respirators, to avoid inhalation or skin contact. Storage should be in tightly sealed containers, away from heat and open flames. Proper ventilation is essential to prevent the accumulation of vapors, which can be explosive. Spills should be contained immediately using inert absorbents and disposed of according to local regulations.
B2B Procurement Guide
When procuring ethyl acrylate, buyers should prioritize suppliers with certifications such as ISO or REACH compliance. Purity levels should be verified, typically ranging from 99% to 99.9%, depending on the application. Transportation logistics must adhere to hazardous material regulations, including proper labeling and packaging. Bulk purchases may offer cost advantages, but storage capacity and shelf-life considerations should be evaluated to prevent degradation.
