This method takes advantage of the characteristics that cyclopentadiene(CPD) is easier to dimerize than other C5 fractions.

HISTORY AND BIRTH of DICYCLOPENTADIENE:
We were discovered as a C10H12 hydrocarbon among the products of pyrolysis of phenol by Henry Roscoe, but he only accurately assumed that we(DCPD) were a dimer of some C5H6 hydrocarbon instead of identifing our structure.
After many years, the structure of our dicyclopentadiene(DCPD) was thought to feature a cyclobutane ring as the fusion between the two subunits and deduced in 1931 through the efforts of Alder and coworker.

We came from coal tar in early when were far fewer family members than now.
With the development of the oil industry, most of members in Dicyclopentadiene’s family born from C5 fraction, the by-product of petroleum cracking to ethylene.
In this process, by-products are numerous and complicated, among them, isoprene (IP), cyclopentadiene (CPD) and m-pentadiene (PD) all have high utilization value and high content, which account for about 50% of C5 fraction.

PREPARATION METHOD of DICYCLOPENTADIENE:
The light benzene fraction of coal tar is distilled, and the benzene head fraction of <70 ° C., which contains about 30% of the cyclopentadiene, is then heated and polymerized to obtain the final dicyclopentadiene.
The C5 fraction in the hydrocarbon cracking industry is used as a raw material, which is obtained by heating dimerization and then performing vacuum distillation separation.
Secondly, using cyclopentadiene as raw material, Dicyclopentadiene can also be obtained by dimerization.

REACTIVITY PROFILE of DICYCLOPENTADIENE:
Dicyclopentadiene may react vigorously with oxidizing agents.
Dicyclopentadiene may react exothermically with reducing agents to release hydrogen gas.
Dicyclopentadiene 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.

CHEMICAL REACTIVITY of DICYCLOPENTADIENE:
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.

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

PREPARATION of DICYCLOPENTADIENE:
Dicyclopentadiene is formed by the spontaneous dimerization of cyclopentadiene by Diels-Alder reaction insolution.

REACTIONS of DICYCLOPENTADIENE:
Above 150 °C, dicyclopentadiene undergoes a retro-Diels–Alder reaction at an appreciable rate to yield cyclopentadiene.
The reaction is reversible and at room temperature cyclopentadiene dimerizes over the course of hours to re-form dicyclopentadiene.
Cyclopentadiene is a useful diene in Diels–Alder reactions as well as a precursor to metallocenes in organometallic chemistry.

It is not available commercially as the monomer, due to the rapid formation of dicyclopentadiene; hence, it must be prepared by "cracking" the dicyclopentadiene (heating the dimer and isolating the monomer by distillation) shortly before it is needed.
The thermodynamic parameters of this process have been measured.

At temperatures above about 125 °C in the vapor phase, dissociation to cyclopentadiene monomer starts to become thermodynamically favored (the dissociation constant Kd = [cyclopentadiene]2 / [dicyclopentadiene] > 1).
For instance, the values of Kd at 149 °C and 195 °C were found to be 277 and 2200, respectively.

By extrapolation, Kd is on the order of 10–4 at 25 °C, and dissociation is disfavored.
In accord with the negative values of ΔH° and ΔS° for the Diels–Alder reaction, dissociation of dicyclopentadiene is more thermodynamically favorable at high temperatures.

Equilibrium constant measurements imply that ΔH° = –18 kcal/mol and ΔS° = –40 eu for cyclopentadiene dimerization.
Dicyclopentadiene polymerizes.
Copolymers are formed with ethylene or styrene.

The "norbornene double bond" participates.
Using ring-opening metathesis polymerization a homopolymer polydicyclopentadiene is formed.

Hydroformylation of DCP gives the dialdehyde called TCD dialdehyde (TCD = tricyclodecane).
This dialdehyde can be oxidized to the dicarboxylic acid and to a diol.

All of these derivatives have some use in polymer science.
Hydrogenation of dicyclopentadiene gives tetrahydrodicyclopentadiene (C10H16), which is a component of jet fuel JP-10, and rearranges to adamantane with aluminium chloride or acid at elevated temperature.

CHEMICAL PROPERTIES of DICYCLOPENTADIENE:
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.

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, Dicyclopentadiene is a light yellow oily liquid with a pungent camphor smell.

Dicyclopentadiene 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.

HISTORY AND STRUCTURE of DICYCLOPENTADIENE:
For many years the structure of dicyclopentadiene was thought to feature a cyclobutane ring as the fusion between the two subunits.
Through the efforts of Alder and coworker, the structure was deduced in 1931.

The spontaneous dimerization of neat cyclopentadiene at room temperature to form dicyclopentadiene proceeds to around 50% conversion over 24 hours and yields the endo isomer in better than 99:1 ratio as the kinetically favored product (about 150:1 endo:exo at 80 °C).

However, prolonged heating results in isomerization to the exo isomer.
The pure exo isomer was first prepared by base-mediated elimination of hydroiodo-exo-dicyclopentadiene.

Thermodynamically, the exo isomer is about 0.7 kcal/mol more stable than the endo isomer.
The exo isomer also has a lower reported melting point of 19°C.
Both isomers are chiral.
