For industrial buyers and R&D professionals, a deep understanding of the chemical properties and synthesis of key intermediates is essential for successful product development and procurement. 2-(Dimethylamino)ethyl Acrylate (DMAEA), CAS 2439-35-2, is one such versatile monomer whose unique chemistry underpins its widespread applications. As a dedicated manufacturer and supplier, we aim to provide clarity on these aspects to facilitate informed purchasing decisions.

At its core, DMAEA is an ester of acrylic acid and 2-dimethylaminoethanol. Its molecular structure, H2C=CHCO2CH2CH2N(CH3)2, reveals two primary functional groups: the vinyl group of the acrylate ester, which readily participates in free-radical polymerization, and the tertiary amine group. This dual functionality is the source of DMAEA's remarkable versatility.

The acrylate moiety allows DMAEA to act as a monomer in the creation of homopolymers and copolymers. It readily copolymerizes with a wide array of other vinyl monomers, including other acrylates, methacrylates, acrylonitrile, styrene, and vinyl acetate. This copolymerization capability enables the precise tailoring of polymer properties, such as glass transition temperature, solubility, and mechanical strength.

The tertiary amine group, however, is what truly sets DMAEA apart. This basic functional group imparts several critical characteristics to polymers containing DMAEA. Firstly, it confers pH responsiveness. In acidic conditions, the amine group becomes protonated, increasing the hydrophilicity and often the solubility of the polymer. As the pH rises, the amine group deprotonates, altering the polymer's properties, such as swelling behavior or charge density.

Secondly, the amine group acts as a site for quaternization. Reaction with alkylating agents, such as methyl chloride or dimethyl sulfate, converts the tertiary amine into a permanent quaternary ammonium cation. This process is crucial for producing highly cationic polymers, which are widely used as flocculants, coagulants, and retention aids in industries like papermaking and wastewater treatment. For manufacturers in these sectors looking to buy DMAEA, understanding this quaternization pathway is key.

The synthesis of DMAEA is typically achieved through transesterification. A common industrial route involves reacting methyl acrylate or ethyl acrylate with 2-dimethylaminoethanol under acid catalysis. Careful control of reaction conditions, including the use of polymerization inhibitors, is essential to prevent premature polymerization of the highly reactive acrylate. Purification, often via vacuum distillation, is then performed to achieve the desired purity. As a manufacturer, we meticulously manage these synthesis and purification steps to ensure the high quality of the DMAEA we supply.

The physical properties of DMAEA are also important for its industrial handling and application. It is generally a colorless to light yellow liquid with a characteristic amine-like odor. Its solubility in water and common organic solvents, along with its boiling point and flash point, are critical parameters for process design and safety. We provide comprehensive safety data sheets (SDS) and technical specifications to all our customers who purchase DMAEA.
