Methoxyethyl Acrylate stands out as a distinct chemical used widely in manufacturing and applied chemistry. The organic compound, often included among acrylate esters, features a clear and nearly colorless to pale yellow liquid appearance. People usually work with this substance in industrial environments because it reacts quickly to form polymers and co-polymers, making it valuable for coatings, adhesives, and certain specialty plastics. Chemists know it under the IUPAC name 2-methoxyethyl acrylate, and its CAS Number is 3121-61-7. Another identity marker, the HS Code, is 2916.14.00, useful for trade and regulatory tracking. Methoxyethyl Acrylate’s molecular formula is C6H10O3, with a precise molar mass of 130.14 g/mol, which matters for anyone scaling reactions or ordering raw material in bulk.
Industry experience shows Methoxyethyl Acrylate works well for more than just one niche. Large-scale commercial printers value it for its low odor and good adhesion to substrates in ink or coating formulations. In my years working with coatings manufacturers, I have seen how formulations with this acrylate resist yellowing and demonstrate flexibility—important factors for automotive or architectural surfaces that get exposed to the environment. Its ability to act as a co-monomer makes it popular for specialty adhesives or tough resins. Battery separators, fibers, and hydrogels also make substantial use of its polymer properties. Raw materials like this acrylate can raise both efficiency and product quality, especially for companies looking to meet strict performance benchmarks.
Looking at the physical data, Methoxyethyl Acrylate remains liquid at room temperature, with a boiling point of 172°C (342°F) and a melting point close to -68°C (-90°F). It smells faintly sweet and carries a density of about 1.02 g/cm³ at 20°C, which provides helpful context for mixing, storage, and handling compared to water or other chemicals. Solubility comes up often in my conversations with process engineers—this material dissolves easily in organic solvents like alcohols or ethers, though it blends less readily with water. Flakes, pearls, solid, or powder forms do not generally occur; Methoxyethyl Acrylate most often arrives and ships as a stable liquid in drums or bulk containers. The refractive index, usually around 1.425, speaks to its use in optically sensitive applications, though viscosity and volatility generally steal the spotlight for manufacturing decisions.
On the chemical side, Methoxyethyl Acrylate belongs to the group of acrylate esters, and its structure includes an acrylate group (CH2=CHCOO-) joined to a 2-methoxyethyl chain (-CH2CH2OCH3). This structure underpins both its performance and hazards. Methoxyethyl Acrylate’s double bonds support easy polymerization, which makes it handy in plastic or adhesive synthesis. I have found that the unique arrangement of the methoxyethyl substituent lends flexibility and hydrophilicity to final polymer products, distinguishing it from other acrylates in a crowded specialty chemicals market. Understanding that molecular structure can make a difference—chemists seeking higher hydrolytic resistance or better flow properties often select Methoxyethyl Acrylate for custom resin jobs.
Suppliers usually guarantee Methoxyethyl Acrylate above 99% purity (GC), with moisture kept below 0.05% to protect against premature polymerization. Standard containers range from 200-liter drums to large IBC tanks. Based on my work with procurement and logistics staff, it’s clear that clear communication of required density and purity pays off. The density, right around 1.02 g/cm³, simplifies blending with other acrylic monomers. During product development or plant trials, I encourage teams to keep a close eye on batch test results for impurities or variable density. Many manufacturers recommend stabilizing the liquid with additives (like MEHQ) to prevent runaway reactions during storage or transport.
Experience working in an industrial R&D lab counts for a lot when emphasizing the safety risks. Methoxyethyl Acrylate contains reactive double bonds and acts as both a skin and eye irritant. Exposure causes redness, stinging, or dermatitis—nobody wants to skip gloves after witnessing even a mild splash. The vapor carries a risk of respiratory tract irritation if released in a poorly ventilated room. Less often discussed: chronic exposure can cause harm to the kidneys or liver, based on repeat animal tests. Data sheets list the flash point between 57–61°C, which marks it as a flammable liquid and a reason strict fire precautions apply. Emergency teams at manufacturing sites often prefer full-face respirators and chemical aprons during spills or cleanup.
Safe work practices start with personal protective equipment. Goggles, gloves, and chemical-resistant aprons remain non-negotiable in my own lab work. Emergency showers and eyewash stations function best where fast action is possible. Storage protocols recommend tightly closed containers, away from sources of ignition, strong bases, or acids. Based on accident case studies, stable room temperature away from sunlight limits the risk of unwanted polymerization. Site managers also structure facilities to avoid electrostatic discharge, as this chemical can build static and cause flash fires. Waste material falls under hazardous waste regulations; neutralizing or segregating the acrylate before disposal prevents environmental issues. Firefighters need to know: water spray works for cooling containers, but foam or dry powder perform better on burning methoxyethyl acrylate spills.
Reliable sources for Methoxyethyl Acrylate usually trace back to major chemical producers across Asia, Europe, and North America. Large-scale operations favor direct shipments with every batch tested for compliance. Pricing fluctuates, affected by raw acrylic acid, methoxyethanol sources, and transport costs. Procurement teams monitor supply chain disruptions, such as port closures or regulatory changes, because a small hiccup can interrupt downstream product lines. The push to reduce petrochemical footprints has led some users to seek bio-based acrylate intermediates, though large-scale sustainable sourcing isn’t common yet. Industry efforts include research into closed-loop solvent recovery, energy-saving polymerization processes, and engineering controls cutting fugitive emissions. Best results come when plant engineers, safety specialists, and environmental staff work together from the start of the sourcing process.
Working with Methoxyethyl Acrylate means wrestling with safety, efficiency, and sustainability. I have seen a lot of progress just by tightening up training and sharing incident data among plant staff. Upgraded ventilation systems and improved engineering controls cut exposure risks. Manufacturers who set up real-time sensors for leaks or temperature spikes avoid both product loss and serious accidents. Switching from glass to lined steel storage tanks improves compatibility and keeps material stable. Some research teams experiment with greener co-monomers or process intensification to use less hazardous solvents or raw materials. Open dialogue between regulators and operators means hazard management can improve, not just on paper. These simple, practical steps make a measurable difference—in people’s safety, in waste reduction, and in producing materials that customers expect to work, every single batch.
