The Uses of 5-ETHYLIDENE-2-NORBORNENE

As third monomer in EPDM (ethylene- propylene diene monomer)

Definition

A diene used as the third monomer in EPDM elastomers.

General Description

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

Air & Water Reactions

Flammable. Insoluble in water.

Reactivity Profile

5-ETHYLIDENE-2-NORBORNENE 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.

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.

Fire Hazard

5-ETHYLIDENE-2-NORBORNENE is flammable.

Safety Profile

Moderately toxic by ingestion. Mildly toxic by inhalation and sh contact. Human systemic effects by inhalation: conjunctiva, olfactory, and taste changes. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

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.

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

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
