2-Ethylhexyl acrylate, also known as 2-Ethylhexyl 2-propenoate, is an organic compound with the formula C11H20O2. It is colorless transparent liquid which is slightly soluble in water and complete soluble in alcohols and ethers. 2-Ethylhexyl acrylate contains a double bond and functional carboxyl group which can make 2-ethylhexyl acrylate form homopolymers and copolymers.
Preparation of 2-Ethylhexyl acrylate: 2-Ethylhexyl acrylate can be obtained by many methods.
1. Direct esterification: First, go through esterification of acrylic acid and 2-ethylhexanol in the presence of sulfuric acid catalyst. And then, after neutralization, dealcoholization and distillation, 2-ethylhexyl acrylate can be obtained.
2. Transesterification: The acrylic acid 2-ethylhexyl ester can be produced by transesterification from methyl acrylate and 2-ethylhexanol in the presence of titanium tetrachloride catalyst. Then 2-ethylhexyl acrylate can be obtained by distillation.
3. Add a certain amount of acrylic acid, isooctyl alcohol, catalyst (SO42-/ZrO2) and polymerization inhibitor phenothiazine in the reactor. Heat and reflux until no water is out. Then, after alkali washing and water washing to neutral, go through vacuum distillation to collect the 2-ethylhexyl acrylate. Catalyst dosage is 5% of acrylic acid quality, and polymerization inhibitor dosage is 0.05% of acrylic acid quality. The ratio of raw materials ethylhexanol: acrylic acid is 1.2:1. The reaction temperature is 120 °C and the reaction time is 3h.
Uses of 2-Ethylhexyl acrylate: 2-Ethylhexyl acrylate is used for the manufacture of coatings, adhesives, fiber and fabric modification, processing aids, leather processing aids, etc. It is also used as a monomer for the soft polymer. What's more, it can serve as plasticizing effect in copolymer. 2-Ethylhexyl crylate can carry out copolymerization, crosslinking and grafting with other monomers to acrylic resin products used for processing of synthetic fabrics, adhesives, coatings, plastics modification, and many other aspects. Besides, it can be used as a solvent. It is also a very useful feedstock for chemical syntheses, because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.
2-Ethylhexyl acrylate may cause sensitisation by skin contact. If swallowed, seek medical advice immediately and show this container or label. Besides, this chemical is irritating to respiratory system and skin. When you are using it, wear suitable protective clothing and gloves.
