Beschreibung
2-Ethylhexyl acrylate is a combustible, colorless liquid with a pleasantodor. Molecular weight = 184.31;Boiling point = 214℃; Freezing/Melting point = -90℃;Flash point = 82℃; Autoignition temperature = 252℃.Explosive limits: LEL = 0.8%; UEL = 6.4%. HazardIdentification (based on NFPA-704 M Rating System):Health 2, Flammability 2, Reactivity 2. Insoluble in water
Chemische Eigenschaften
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.
Charakteristisch
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.
Verwenden
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.
Definition
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.
synthetische
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.
Allgemeine Beschreibung
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.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
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].
Hazard
Questionable carcinogen.
Health Hazard
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.
Brandgefahr
Behavior in Fire: Heat can result in a severe polymerization with rapid release of energy. Sealed containers may rupture explosively if hot.
Flammability and Explosibility
Not classified
mögliche Exposition
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.
Erste Hilfe
Skin Contact: Flood all areas of body thathave contacted the substance with water. Do not wait toremove contaminated clothing; do it under the water stream.Use soap to help assure removal. Isolate contaminatedclothing when removed to prevent contact by others. EyeContact: Remove any contact lenses at once. Flush eyeswell with copious quantities of water or normal saline for atleast 20- 30 min. Seek medical attention. Inhalation: Ifconvulsions are not present, give a glass or two of water ormilk to dilute the substance. Assure that the person’s airwayis unobstructed and contact a hospital or poison centerimmediately for advice on whether or not to induce vomiting. Ingestion: If convulsions are not present, give a glassor two of water or milk to dilute the substance. Assure thatthe person’s airway is unobstructed and contact a hospitalor poison center immediately for advice on whether or notto induce vomiting.
Lager
: Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-ventilated area or refrigeratoraway from oxidizers and light. Where possible, automatically pumpliquid from drums or other storage containers toprocess containers.
Versand/Shipping
Note: Unless inhibited, this material is a polymerization hazard. May be classified as a Combustible liquid, n.o.s. This class of compounds requires no particularshipping label. It falls in Hazard Class 3 and Packing GroupIII. Each reference to a Class 3 material is modified to read“COMBUSTIBLE LIQUID” when that material is reclassified in accordance with y173.150 (e) or (f) of this subchap_x0002_ter, or has a flash point above 60.5℃/141° F but below93℃/200°F.
Inkompatibilitäten
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.
Waste disposal
Spray into incinerator with added flammable solvent.
