| Use | as a polymeric monomer for soft polymers, internal plasticization in the copolymer 2-ethylhexyl acrylate is the monomer of high molecular polymer, and it is copolymerized with other monomers, cross-linked, grafted and so on, used in synthetic fiber fabric processing, adhesives, coatings, plastic modification and many other aspects. 1. Organic synthesis, solvent. 2, polymerizable monomer, used for soft polymer, in the copolymer play a role in the plasticization. 3, for the preparation of coatings, textile, paper, leather, building adhesives and other industrial resins. |
| production method | 1. Direct esterification of acrylic acid and 2-Ethylhexanol with sulfuric acid as catalyst for esterification, followed by neutralization, dealcoholization and distillation to obtain the finished product. 2. Transesterification of methyl acrylate and 2-Ethylhexanol in the presence of titanium tetrachloride as a catalyst, a transesterification reaction is carried out to produce 2-ethylhexyl acrylate, which is then subjected to rectification to obtain a finished product. |
