The properties and uses
of octyl acrylate
1. the properties of octyl acrylate

octyl acrylate, also known as 2-ethylhexyl acrylate, is a colorless and transparent liquid with a strong pungent odor. Its molecular formula is C11H20O2 and its molecular weight is 184.27. Octyl acrylate is chemically stable and not easily hydrolyzed, but it is prone to hydrolysis under acidic and alkaline conditions. In addition, it also has strong UV resistance, oxidation resistance and weather resistance.

octyl acrylate has a solubility parameter of 9.4-9.6 (J/cm³)¹/², which is similar to the solubility parameter of many polymers and resins, so it can be used as a solvent and plasticizer for many high-molecular compounds. In addition, octyl acrylate has a low surface tension and can be used as a surfactant.

2. octyl acrylate use

octyl acrylate as an important chemical production raw materials, widely used in various fields. The following are the main uses of octyl acrylate:

1. Polymer synthesis: octyl acrylate can be used as a monomer, copolymerized with other monomers to generate polymers. For example, it can be copolymerized with styrene, methyl methacrylate and other monomers to obtain a polymer with high transparency, high impact resistance and high heat resistance.
2. Plastic modification: octyl acrylate can be used as a plasticizer and added to plastics to improve the processing performance and use performance of plastics. For example, it can improve the flexibility, impact resistance and processability of polyvinyl chloride plastics.
3. Surfactant: octyl acrylate can be used as a surfactant to improve the wettability, emulsification and dispersibility of the liquid. For example, it can be used as an emulsifier in emulsion polymerization to improve the stability of the emulsion.
4. coatings and adhesives: octyl acrylate can be used as the main component of coatings and adhesives to improve the weather resistance, UV resistance, chemical resistance and other properties of the film and adhesive. For example, it can be used to produce high-performance architectural coatings and automotive coatings.

In short, octyl acrylate as an important chemical production raw materials, has a wide range of uses. The further study of its properties and uses will help to promote the continuous development of the chemical industry.
