Ethyl acrylate reacts with amines catalyzed by Lewis acids in a Michael addition to β-alanine derivatives in high yields: [13]. The nucleophilic addition at ethyl acrylate as an α,β-unsaturated carbonyl compound is a frequent strategy in the synthesis of pharmaceutical intermediates.
Hazardous chemicals present physical and/or health threats to workers in clinical, industrial, and academic laboratories. Laboratory chemicals include cancer-causing agents (carcinogens), toxins (e.g., those affecting the liver, kidney, and nervous system), irritants, corrosives, sensitizers, as well as agents that act on the blood system or damage the lungs, skin, eyes, or mucous membranes.
When ethyl acrylate is used as a reactant, ethanol is formed; this forms with the ethyl acrylate an azeotrope of the composition ethanol/ethyl acrylate 72.7:26.3%, which boils at 77.5 °C under atmospheric pressure. [8] To achieve a high reaction yield, the ethanol is distilled off from the reaction mixture.
Ethyl acrylate was once used as synthetic food flavoring and was withdrawn by FDA possibly due to cancerogenic effects observed in lab animals. [13] Animal studies showed that high-doses of acrylic acid decreased weight gain. Acrylic acid can be converted to non-toxic lactic acid. [14] Acrylic acid is a constituent of tobacco smoke. [15]
An acrylate polymer (also known as acrylic or polyacrylate) is any of a group of polymers prepared from acrylate monomers. These plastics are noted for their transparency, resistance to breakage, and elasticity. Acrylate polymer is commonly used in cosmetics, such as nail polish, as an adhesive. [1]
The acrylate ion is the anion CH 2 =CHCO − 2. Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. These acrylates contain vinyl groups. These compounds are of interest because they are bifunctional: the vinyl group is susceptible to polymerization and the carboxylate group carries myriad ...
Poly(ethyl acrylate) (PEA) is a family of organic polymers with the formula (CH 2 CHCO 2 CH 2 CH 3) n. It is a synthetic acrylate polymer derived from ethyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from ethyl acrylate and other monomers.
"NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [ 1 ] and revised several times since then, it defines the " Safety Square " or " Fire Diamond " which is used to ...
