化學(xué)的特性
A colorless and transparent liquid that is nearly insoluble in water but can be mixed with alcohol and ether. It was present in a surgical tape and caused allergic contact dermatitis in a patient.
特性
2-Ethylhexyl acrylate (2-EHA) is one of the main base monomers used to make copolymers for adhesives and sealants, paints and coatings, printing inks, super absorbent polymers, building materials, acrylic rubbers and emulsions among other applications. 2-EHA is a unique building block for copolymers that provide low temperature flexibility, performance, hydrophobicity, water resistance, good weatherability and UV (sunlight) resistance. 2-EHA monomer has a Tg of – 65°C and has various industrial applications.
使用
2-ethylhexyl acrylate is a monomer for plastics, protective coating, paper treatment, water-based paints, UV-curable coatings, and inks; in so me acrylicbased adhesive tapes.
定義
ChEBI: 2-Ethylhexyl acrylate is an ester of enoic acid. It is commonly used as a plasticizing co-monomer in the production of resins, which are utilized in various applications such as adhesives, latex, paints, textile and leather finishes, and coatings for paper.
製造方法
2-Ethylhexyl acrylate is obtained by esterifying acrylic acid and 2-ethylhexanol with sulfuric acid as a catalyst, and subsequently neutralizing, dealcoholizing and rectifying the mixture.
一般的な説明
2-ethylhexyl acrylate appears as a clear colorless liquid with a pleasant odor. Less dense than water and insoluble in water. Vapors heavier than air. Flash point 180 °F. Used in making of paints and plastics.
空気と水の反応
Insoluble in water.
反応プロフィール
2-Ethylhexyl acrylate polymerizes readily in the presence of heat and light generating much heat; reacts with strong oxidants. REF [Handling Chemicals Safely, 1980. p. 235].
危険性
Questionable carcinogen.
健康ハザード
Inhalation of concentrated vapor causes drowsiness and convulsions. Liquid causes irritation of eyes and may irritate skin on prolonged exposure. Ingestion produces same symptoms as inhalation.
火災(zāi)危険
Behavior in Fire: Heat can result in a severe polymerization with rapid release of energy. Sealed containers may rupture explosively if hot.
職業(yè)ばく露
A potential danger to those involved
in the use of this monomer as a feedstock for chemical syntheses; in the manufacture of plastics; protective coatings,
including water-based paints; in paper treatment; the production of emulsion polymers.
不和合性
Unless inhibited, sunlight, heat, contaminants, or peroxides can cause dangerous polymerization.
Vapors are uninhibited and may polymerize, blocking
vents. Violent reaction with strong oxidizers, with risk of
fire and explosions. May form explosive mixture with air.
Incompatible with strong acids; aliphatic amines;
alkanolamines.
廃棄物の処理
Spray into incinerator with
added flammable solvent.
