Ethyl acrylate is an important organic chemical, widely used in coatings, inks, adhesives, fibers, plastics, pharmaceuticals and other fields. This article will introduce the production process and preparation method of ethyl acrylate.

1. production process

ethyl acrylate production process is usually divided into gas phase method and liquid phase method.

1.1 gas phase method

gas phase method ethyl acrylate production process main process is as follows: ethylene, propylene, air and air mixed into the reactor, through the multi-tubular reactor for oxidation reaction, to produce ethyl acrylate. The parameters in the reactor (temperature, pressure, space velocity) need to be strictly controlled to obtain high quality products. After the reaction, the mixed gas is cooled, separated, and rectified to obtain ethyl acrylate as a product.

gas phase ethyl acrylate production process has the advantages of fast reaction speed and high product purity, but it needs to use a large number of catalysts and oxidants, and there are some safety hazards in the reaction process.

1.2 liquid phase method

liquid phase method ethyl acrylate production process main process is as follows: isoprene and methanol in the reactor for esterification reaction, generating isoamyl formate; then isoamyl formate and acrylic acid for transesterification reaction, to obtain isoamyl acrylate; finally isoamyl acrylate for de isoamyl reaction, ethyl acrylate products. In the reaction process, the addition rate and temperature of the reactants need to be controlled, and the steps of separation, washing, distillation and the like need to be carried out to obtain the high quality product.
the production process of ethyl acrylate by
liquid phase method is relatively simple, more raw materials need to be used and the cost is higher.

2. preparation method

2.1 free radical polymerization

free radical polymerization is a more commonly used method for the preparation of ethyl acrylate. The specific operation steps are as follows: acrylic acid and vinyl acid ethyl ester are mixed according to a certain ratio, and benzoyl peroxide is added as an initiator to carry out polymerization reaction. The product after the reaction can be obtained by steps such as separation, washing, and rectification. Ethyl acrylate prepared by free radical polymerization has high purity, but more initiators and catalysts are needed.
