About Methyl acrylate
Methyl acrylate is an organic compound, more accurately the methyl ester of acrylic acid. It is a colourless liquid with a characteristic acrid odor. It is mainly produced to make acrylate fiber, which is used to weave synthetic carpets.[5] It is also a reagent in the synthesis of various pharmaceutical intermediates.
Methyl acrylate is after butyl acrylate and ethyl acrylate the third most important acrylic ester with a worldwide annual production of about 200,000 tons per year.[15]
Methyl acrylate reacts catalysed by Lewis bases in a Michael addition with amines in high yields to -alanine derivatives which provide amphoteric surfactants when long-chain amines are used and the ester function is hydrolysed subsequently.
Methyl acrylate is used for the preparation of 2-dimethylaminoethyl acrylate by transesterification with dimethylaminoethanol in significant quantities of over 50,000 tons / year.[16]
Methyl acrylate is used as a comonomer in the polymerization with a variety of acrylic and vinyl monomers. In doing so it has a similar range of uses as ethyl acrylate.[17] When using methyl acrylate as comonomer resulting acrylic paints are harder and more brittle than those with the homologous acrylates. Copolymerizing methyl acrylate with acrylonitrile improves their melt process ability to fibers, which could be used as precursors for carbon fibers.[18]
Acrylates are also used in the preparation of poly (amidoamine) (PAMAM) dendrimers typically by Michael addition with a primary amine.
Methyl acrylate is the precursor to fibers that are woven to make carpets.
Owing to its tendency to polymerize, samples typically contain an inhibitor such as hydroquinone.
Key Properties and ApplicationsMethyl acrylate offers a unique combination of reactivity and versatility, making it a valuable ingredient in industrial manufacturing. Owing to its solubility in alcohol and ether, it blends seamlessly for use in polymer synthesis, adhesive production, coatings, and textile treatments. Its clear, colorless appearance and acrid odor are indicative of its high purity and suitability for direct processing in a wide array of formulations.
Safe Storage and Handling GuidelinesDue to its high flammability and toxicity, methyl acrylate must be stored in tightly sealed containers within cool, dry, and well-ventilated areas, away from all ignition sources. Proper handling minimizes health risks from inhalation, skin contact, or ingestion. For chemical stability, it is vital to avoid exposure to heat or light, which can lead to hazardous polymerization if the product is not adequately inhibited.
Supplied Packaging and Shelf LifeMethyl acrylate is primarily packaged in 200 kg drums, ensuring convenient handling and transportation for industrial use. The chemical maintains its properties for up to 12 months when stored in original, unopened containers under recommended conditions. This helps to preserve its performance for manufacturing and processing needs throughout its shelf life.
