Results and discussion
Boiling point
- Key result
- Boiling pt.:
- 22 - 120 °C
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- yes
- Remarks:
- Dicyclopentadiene decomposes into cyclopentadiene at higher temperature
- Decomp. temp.:
- ca. 120 °C
- Remarks on result:
- other: Athmospheric equivalent temperature
Applicant's summary and conclusion
- Conclusions:
- The boiling range was determined according to ASTM D1160 and found to be approximately 22° - 120°C. After distilling approximately 90 %(v/v) the distillation was ended due to cracking, which was most likely caused by decomposition of dicyclopentadiene back in cyclopentadiene.
