2-Carboxyethyl acrylate Usage And Synthesis

Description

2-Carboxyethyl acrylate is a highly versatile monomer extensively used to produce diverse polymers. It can be polymerized in solution or emulsion, producing vinyl-acrylic, acrylic, or styrenic-acrylic polymers with greater flexibility due to lower glass transition of itshomopolymer (<30C) and improved adhesion. It finds applications in various polymer production processes, including those geared towards optical applications like optical fibers, optical waveguides, and optical lenses. Moreover, 2-Carboxyethyl acrylate is instrumental in synthesizing polymers used in energy storage applications, such as fuel cells, batteries, and supercapacitors. 2-carboxyethyl acrylate could be used as a new monomer in the gel casting of alumina. This low-toxic, water-soluble monomer modifies the ceramic suspensions' rheological properties and minimizes the oxygen inhibition's negative effect [1-3].

Chemical Properties

Colorless to light yellow viscid liquid

Uses

2-Carboxyethyl Acrylate is used in the preparation of DNase enzyme derivatives that act as potent preventative material of bacterial adhesion and biofilm formation in biomaterials.

Application

2-Carboxyethyl acrylate can be polymerized in solution or emulsion to produce acrylic, vinyl acrylic, or styrene acrylic polymers, which are distinguished by their low glass transition temperatures (<30°C) as homopolymers. Greater elasticity, as well as improved adhesion.

Preparation

Synthesis of 1-ethoxyethyl acrylate (EEA) and protected 2-carboxyethyl acrylate (proCEA)
EEA and proCEA were synthesized following a previously published procedure and distilled prior to use. For the synthesis of proCEA (Figure 1), phosphoric acid (109 mg, 1.11 mmol) was weighed into a dry round bottom flask in a glovebox and then taken outside the glovebox, taking care that the phosphoric acid stayed dry. 2-Carboxyethyl acrylate (80 g, 555 mmol) and ethyl vinyl ether (48 g, 666 mmol) were added and the reaction was stirred for two days at room temperature. Hydrotalcite (Mg6Al2(OH)16CO3·4H2O, ~1 g) was added, stirred for one hour and filtered off. Excess ethyl vinyl ether was removed under reduced pressure and the product was distilled under reduced pressure (80 °C, 1.3 mbar).

Hazard

A severe skin irritant.
