Dicyclopentadiene Usage And Synthesis

Chemical Properties

colourless crystals with a camphor-like odour

Chemical Properties

Cyclopentadiene is a crystalline solid or a liquid (above 32°C) with a disagreeable, camphor-like odor. The Odor Threshold is 0.011 (detectable); 0.020 ppm (recognizable).

Chemical Properties

Dicyclopentadiene is a colorless, crystalline combustible solid.

Uses

It is used in the synthesis of chlorinated hydrocarbon pesticides and ferrocene; in paint, varnish, and resin manufacture; in elastomers used as water pond liners, and as a repellent for animals such as hares, rabbits, and deer, in winter or in summer. It is applied in the form of impregnated strip on deciduous and coniferous trees, or by spraying around ornamental plants and shrubs.

Production Methods

Dicyclopentadiene is produced by recovery from hydrocarbon streams from high temperature cracked petroleum fractions. It is also a by-product of the coke oven industry. Cyclopentadiene polymerizes to dicyclopentadiene on standing.

Production Methods

Dicyclopentadiene is produced by thermal cracking of petrochemical feedstocks or as a by-product of the coke oven industry. It is also formed by spontaneous dimerization of cyclopentadiene.

General Description

A liquid with an acrid odor. Flash point 90°F. The vapors are irritating to the eyes and respiratory system. Subject to polymerization if subjected to heat for prolonged periods or if contaminated. If the polymerization takes place inside a container, the container may violently rupture. Insoluble in water. Density 8.2 lb / gal. Used in paints, varnishes, as an intermediate in insecticides, as a flame retardant in plastics.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

Dicyclopentadiene may react vigorously with oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. Can undergo exothermic polymierization reactions In the presence of various catalysts (such as acids) or initiators, if subjected to heat for prolonged periods, or if contaminated. Many undergo autoxidation upon exposure to the air to form explosive peroxides.

Health Hazard

LIQUID OR SOLID: Irritating to skin and eyes.

Fire Hazard

FLAMMABLE. Flashback along vapor trail may occur. Vapor may explode if ignited in an enclosed area.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: May occur in presence of acids, but not hazardous; Inhibitor of Polymerization: Not pertinent.

Safety Profile

Poison by ingestion and intraperitoneal routes. Moderately toxic by inhalation. Mildly toxic by skin contact. A severe skin and moderate eye irritant. Dangerous fire hazard when exposed to heat or flame; can react with oxidizing materials. To fight fire, use alcohol foam. When heated to decomposition it emits acrid smoke and fumes.

Potential Exposure

This compound is used in the manufacture of cyclopentadiene as a pesticide intermediate; in the production of ferrocene compounds; in paints, varnishes, and resin manufacture; in production of elastomers, resin systems, and polymers.

Shipping

UN2048 Dicyclopentadiene must carry a “FLAMMABLE LIQUID” label. It falls in Hazard Class 3

Incompatibilities

Forms explosive mixture with air above flash point. Depolymerizes at boiling point and forms two molecules of cyclopentadiene; unless inhibited and maintained under inert atmosphere to prevent polymerization. Violent reaction with strong oxidizers; strong acids; strong bases. Can accumulate static electrical charges, and may cause ignition of its vapors

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.
