What is hydroxyethyl acrylate-JINDUN CHEMICAL

End-hydroxy polybutadiene manufacturer of the editor today to take you to know about hydroxyethyl acrylate products, hydroxyethyl acrylate scientific name is ethyl p-hydroxybenzoate, the product with ethyl p-hydroxybenzoate and ethanol esterification. It is an ester, usually used as an antibacterial preservative.
　　Hydroxyethyl acrylate is used as a preservative in food, pharmaceuticals and cosmetics. May cause contact dermatitis, urticaria, angioedema, and pain and irritation in contact with eyes. May sting on contact with lips. Ethyl acrylate structure colorless liquid. Density 0.9405. Refractive index 1.404. Melting point -72°C, boiling point 99.8°C. Almost insoluble in water, soluble in ethanol and ether. Easy to polymerize, also can be copolymerized with other monomers. It can be used in the preparation of plastics, resins and other polymers, and can also be used as intermediates in organic synthesis. It is prepared by reacting 3-hydroxypropionitrile with ethanol and sulfuric acid, or by esterifying ethanol to acrylic acid.
　　The specific synthesis of hydroxyethyl acrylate is as follows: the addition reaction of acrylic acid and ethylene oxide in the presence of a catalyst and copolymer inhibitor yields the crude product of 2-hydroxyethyl acrylate. After adenosine and distillation, the raw material consumption quota of the finished product is 710kg / t of acrylic acid and 485kg / t of ethylene oxide.
　　Hydroxypropyl acrylate (HPA) is a (hetero)bifunctional monomer with a wide range of applications. HPA is used in fiber processing to improve the water resistance, solvent resistance and wrinkle resistance of fibers. HPA is copolymerized with ethylene monomers to form adhesives with strong bonding strength. The copolymerization of HPA with acrylate synthetic rubber exhibits good heat and oil resistance. Paper surfaces coated with HPA emulsions can improve the water resistance and strength of paper. HPA can also be used as an additive to lubricants. In addition, HPA is an intermediate for organic reactions and an excellent solvent.
