Allgemeine Beschreibung
Clear to faintly opalescent liquid. Used as a monomer for resins, as an oil additive, ore flotation agent; and dye acceptor.
Reaktivität anzeigen
2-Methyl-5-vinylpyridine neutralizes acids in exothermic reactions to form salts plus water. Can polymerize exothermically. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Health Hazard
2-Methyl-5-vinylpyridine is moderately toxic by ingestion, inhalation, and absorption through the skin.
Brandgefahr
When heated to decomposition, 2-Methyl-5-vinylpyridine emits toxic fumes of nitrogen oxides. (Non-Specific -- Combustible Liquid, n.o.s.) Flammable/combustible material; may be ignited by heat, sparks, or flames. Vapors may travel to a source of ignition and flash back. Container may explode in heat of fire.
mögliche Exposition
2-Methyl-5-vinylpyridine is used as a monomer for resins; oil additive; ore flotation agent; and dye acceptor.
Erste Hilfe
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.
Lager
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from oxidizers. Where possible,automatically pump liquid from drums or other storage containers to process containers.
