Raw materials And Preparation Products

Hazard Information

General Description

Colorless liquid with an odor of turpentine. Flash point 101°F. Floats on water.

Reactivity Profile

ETHYLIDENE NORBORNENE(16219-75-3) may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.

Air & Water Reactions

Flammable. Insoluble in water.

Hazard

Toxic.

Health Hazard

Inhalation of vapors causes headache, confusion, and respiratory distress. Ingestion causes irritation of entire digestive system. Aspiration causes severe pneumonia. Contact with liquid causes irritation of eyes and skin.

Potential Exposure

5-Ethylidene-2-norbornene is used as the third monomer in terpolymer elastomers. Those engaged in the synthesis of pharmaceuticals; pesticides, or in the preparation of specialty resins.

Fire Hazard

This chemical is flammable.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Shipping

UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required.

Incompatibilities

May form explosive mixture with air. Reacts violently with strong oxidants. Violent reaction with oxygen and strong oxidizers. May accumulate static electrical charges, and may cause ignition of its vapors. The substance may polymerize. Inhibit peroxide formation with tert-butyl catechol. ENB should be stored in a nitrogen atmosphere since it reacts with oxygen

Chemical Properties
