colorless liquid. Melting point -70°C, boiling point 90-92°C (1.6kPa), 74-75°C (667Pa), relative density 1.1098 (20/4°C), refractive index 1.446Chemicalbook9, flash point (open cup) 104°C, viscosity 5.34mPa ·S (25°C). It is miscible with water and soluble in general organic solvents. Commercial products generally contain 400 ppm of polymerization inhibitor hydroquinone monomethyl ether.
This product can be copolymerized with many monomers such as acrylic acid and esters, acrolein, acrylonitrile, acrylamide, methacrylonitrile, vinyl chloride, styrene, etc. The resulting product can be used to treat fibers and improve the water resistance and resistance of fibers. Solvent resistance, wrinkle resistance and water resistance; it is also used in Chemicalbook to manufacture thermosetting coatings and synthetic rubbers with excellent performance, as a lubricant additive, etc. In terms of adhesives, copolymerization with vinyl monomers can improve its bonding strength. In paper processing, it can be used to make acrylic emulsion for coating to improve its water resistance and strength.
It is used as a reactive diluent and crosslinking agent in radiation curing systems, and also as a resin crosslinking agent, plastics, rubber modifiers, wood varnishes, printing inks and adhesives. Used in the manufacture of thermosetting acrylic coatings, light-curing acrylic coatings, photosensitive coatings, adhesives, textile treatment agents, paper processing, water quality stabilizers and polymer materials, etc. It has the characteristics of low usage, but can significantly improve the performance of the product.
Acrylic acid and ethylene oxide undergo an addition reaction in the presence of a catalyst and polymerization inhibitor to produce a crude product of 2-hydroxyethyl acrylic acid. After degassing and distillation, the raw material consumption quota of the finished product: acrylic acid 710kg/t, Ethylene oxide is 485kg/t.
