METHYLCYCLOPENTADIENE DIMER Usage And Synthesis
Chemical PropertiesClear colorless to slightly yellow liquid
UsesHigh-energy fuels, curing agents, plasticizers,resins, surface coatings, pharmaceuticals, dyes.
UsesMethylcyclopentadiene dimer is used to study the competition with ethylene for binding and biological activities. Used in the synthesis of rubbers and resins intended for use in contact with food or drink.
General DescriptionA colorless liquid. Slightly less dense than water and insoluble in water. Hence floats on water. Flash point 140°F.
Air & Water ReactionsFlammable. Insoluble in water.
Reactivity ProfileMETHYLCYCLOPENTADIENE DIMER may react vigorously with strong oxidizing agents. Can react exothermically with reducing agents to release gaseous hydrogen. May undergo autoxidation upon exposure to the air to form explosive peroxides. Explosions in ammonia synthesis gas have been traced to the breakdown of addition products of dienes similar to this diene and oxides of nitrogen produced from the interaction of nitrogen oxide and oxygen [Bretherick, 1995].
HazardModerate fire risk.
Health HazardHarmful if swallowed, inhaled or absorbed through skin. Vapor or mist is irritating to the eyes, mucous membrane, upper respiratory tract. Exposure can cause nausea, headache, and vomiting. May contain 0.5% Benzene, a known carcinogen.
Fire HazardSpecial Hazards of Combustion Products: Vapors may travel considerable distance to a source of ignition and flash back. Forms explosive mixtures in air. Container explosion may occur under fire conditions.
Flammability and ExplosibilityFlammable
