| 1,3-Cyclopentadiene Usage And Synthesis |
| Chemical Properties | colourless liquid |
| Uses | manufacture of resins; in organic synthesis as the diene in the Diels-Alder reaction producing sesquiterpenes, synthetic alkaloids, camphors. |
| General Description | 1，3-Cyclopentadiene is a colorless liquid with an irritating, terpene-like odor. Bp: 42.5°C; Flash point: 77°F. Density: 0.805 g cm-3. |
| Reactivity Profile | 1，3-Cyclopentadiene is incompatible with strong oxidizing agents. Ignites on contact with oxygen (O2) and ozone (O3). Explodes on contact with fuming nitric acid or a mixture of sulfuric acid and nitrogen tetroxide. Reacts vigorously on contact with potassium hydroxide and other strong bases. Mixtures with air are explosive. Presents a moderate explosion hazard when exposed to heat or flame. Decomposes violently at high temperature and pressure. May form explosive peroxides in storage. Undergoes a spontaneous dimerization at room temperature to give DI1，3-Cyclopentadiene (C10H12, CAS No: 77-73-6), which is a low-melting solid (melting point: 32.5°C). The reaction is strongly exothermic (Hazardous Chemicals Desk Reference, p. 360 (1987)), but occurs sufficiently slowly that 1，3-Cyclopentadiene can be said to be stable at room temperature. The dimerization accounts for the partial or complete solidification of liquid 1，3-Cyclopentadiene in storage. Polymerization occurs more rapidly and extensively at higher temperatures. When heated to 180-200°C, 1，3-Cyclopentadiene gives poly1，3-Cyclopentadiene, a white waxy solid. Stronger heating breaks down poly1，3-Cyclopentadiene and re-generates the monomeric 1，3-Cyclopentadiene as a vapor. The vapor decomposes violently at higher temperatures and pressures. |
