Dicyclopentadiene Chemical Properties,Uses,Production
Description
Cyclopentadiene is a crystalline solid or a liquid (above 32℃) with a disagreeable, camphor-like odor.The odor threshold is 0.011 (detectable); 0.020 ppm (recog_x005fnizable). Molecular weight=132.22; Boilingpoint=decomposes at 172.2℃; Freezing/Melting point 532℃; Vapor pressure=1.4 mmHg at 20℃; Flash point =32℃; Autoignition temperature=503℃. HazardIdentification (based on NFPA-704 M Rating System):Health 1, Flammability 3, Reactivity 1. Explosive limits:LEL=0.8; UEL=6.3. Practically insoluble in water;solubility=0.02%.
Chemical Properties
Dicyclopentadiene (DCPC) is a dimer of cyclopentadiene. First heating is used to copolymerize cyclopentadiene into dicyclopentadiene, dicyclopentadiene is separated from other light components (boiling point <45°C) by distillation, and then other required dienes, monocyclopentadiene are separated by solvent extraction. Alkene and saturated hydrocarbon components. High-purity dicyclopentadiene is a colorless crystal at room temperature. When it contains impurities, it is a light yellow oily liquid with a pungent camphor smell. It is insoluble in water and soluble in organic solvents such as alcohol and ether.
cyclopentadiene, although a stable molecule, has a strong tendency to form the more stable dimer dicyclopentadiene. This dimerisation already takes place at room temperature and its rate rapidly increases with elevated temperatures. This reaction however is reversible too; dicyclopentadiene "cracks" at temperatures above 140°C to form two cyclopentadiene molecules.
Uses
Dicyclopentadiene is used in resins, particularly unsaturated polyester resins. It plays a major role in inks, adhesives and paints. It is also used as a monomer in polymerization reactions. It is a precursor for the preparation of endo-tetrahydrodicyclopentadiene, which reacts with aluminum chloride at higher temperature to give adamantine. It undergoes a retro-Diels-Alder reaction to yield cyclopentadiene, which acts as ligand in inorganic chemistry.
Uses
Dicyclopentadiene has attracted attention as a building block for the production of modified hydrocarbon resins, which show increased reactivity in copolymerizations with drying oils and produce paint resins with improved drying rate, gloss, and hardness. dicyclopentadiene is used in the modification of tung oil, linseed oil, soybean oil, fish oil, etc., which can speed up drying and improve water resistance and alkali resistance.
Definition
ChEBI: Dicyclopentadiene is a cyclic olefin.
Preparation
Dicyclopentadiene is formed by the spontaneous dimerization of cyclopentadiene by Diels-Alder reaction insolution.
Application
Dicyclopentadiene is mainly used in pharmaceuticals, pesticides, synthetic resins, spices, synthetic rubber and other fields. It can be used to produce adamantane, 2-Chloro-5-chloromethylpyridine, metallocene, glutaraldehyde, carbamate, epoxy resin curing agent, flame retardant, dicyclopentadiene chloride (insecticide), etc.
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.
General Description
Dicyclopentadiene appears as 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.
Mechanism of action
Various routes, acts as a repellent via odour but is also a stomach and vapour toxin
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.
First aid
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. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.
Carcinogenicity
Undiluted dicyclopentadiene caused minor
irritation when applied to the skin of rabbits,
and only trace injury occurred when instilled in
the eye.
Dicyclopentadiene has a camphorlike
odor with a 100% recognition threshold of
0.02ppm; however, there may not be noticeable
irritation below 10ppm.
The 2003 ACGIH threshold limit valuetime-
weighted average (TLV-TWA) for dicyclopentadiene
is 5ppm (27mg/m3).
storage
Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.May form peroxides in storage. Prior to working with thischemical you should be trained on its proper handling andstorage. Before entering confined space where this chemicalmay be present, check to make sure that an explosive concentration does not exist. Store in tightly closed containersin a cool, well-ventilated area away from oxidizing materials, strong acids, and strong bases. Sources of ignition, suchas smoking and open flames, are prohibited where thischemical is used, handled, or stored in a manner that couldcreate a potential fire or explosion hazard. Metal containersinvolving the transfer of=gallons or more of this chemicalshould be grounded and bonded. Drums must be equippedwith self-closing valves, pressure vacuum bungs, and flamearresters. Use only nonsparking tools and equipment, especially when opening and closing containers of thischemical.
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
Toxics Screening Level
The initial threshold screening level (ITSL) for dicyclopentadiene is 1 μg/m3 based on an annual averaging time.
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.
