The problem with cyclopentadiene
Thread Content
I’ve encountered a problem recently and would like to ask everyone for advice: trace amounts of cyclopentadiene in the solvent need to be removed. How can the following methods be used to achieve this? 1. If distillation is used, how can the cyclopentadiene-containing material at the top of the tower be further processed using thermal polymerization to remove the cyclopentadiene? 2. If a hydrogenation method is used, what catalyst should be employed? Are there any materials or results in this regard? Please give some advice
If hydrogenation is used, there are many available catalysts, such as IFP’s LD-265 and LD-341. Domestically, various catalysts are produced by the Shanghai Institute and the Lanzhou Institute (which are essentially hydrodesulfurization catalysts for cracked gasoline); cyclopentadiene can be hydrogenated to cyclopentene.
Can cyclopentadiene be hydrogenated to cyclopentane?
