Ethyl Acrylate Purity 99.5% Ea CAS No 140-88-5 C5h8o2 205-438-8 Acrylate D'ethyle Acrylated’ Ethyle Ethyl Ester

Physical and Chemical Properties
Ethyl acrylate, abbreviated as EA, is a colorless and volatile liquid with a spicy odor. It can be used as an important component in the synthesis of adhesives, coatings, plastics, and textile auxiliaries. Acrylic acid ethyl ester can also be used as a monomer for polymer synthesis materials, and its copolymer with ethylene is a hot melt adhesive; The copolymer with 5% chloroethyl vinyl ether is a synthetic rubber with good oil and heat resistance, and can replace nitrile rubber in some cases.

Application
Ethyl acrylate is an intermediate used in the preparation of the carbamate insecticide carbendazim. It can also be used as a raw material for protective coatings, adhesives, and paper impregnating agents. Its polymer can be used as a crack inhibitor for leather. Its copolymer with ethylene is a hot melt adhesive, and its copolymer with 5% chloroethyl vinyl ether is a synthetic rubber with good oil and heat resistance. In some cases, it can replace nitrile rubber.

Synthetic Method
There are six synthesis methods for ethyl acrylate: ethylene cyanohydrin method, high-pressure Rapper method, improved Rapper method, β - propanedione method, hydrolysis method of acrylonitrile and alcohol, and propylene oxidation method. The current industrial production methods include acrylonitrile method, β - lactone method, Rapper method using acetylene as raw material, and propylene oxidation method, among which propylene oxidation method is currently the most widely used method. The propylene oxidation method first oxidizes propylene to acrolein, and then further oxidizes it to acrylic acid. Then, acrylic acid and ethanol are continuously esterified in the presence of an ion exchange resin catalyst at boiling point temperature to obtain ethyl acrylate.
