Process for producing cyclopentadiene or derivatives thereof and apparatus for the same, and process for producing metallocenes or derivatives thereof |
| abstract |
The present invention provides a process for producing cyclopentadiene or a derivative thereof by heating a mixture containing at least one of dicyclopentadiene or a derivative thereof, the process comprising: a first step comprising heating the mixture into vapor; a second step comprising maintaining while heating the vapor at a temperature higher than the boiling point of the desired cyclopentadiene or derivative thereof to condense and remove high-boiling components and simultaneously collect residual vapor; and a third step comprising maintaining while heating the collected vapor at a temperature lower than the boiling point of the desired cyclopentadiene or derivative thereof to condense and collect the cyclopentadiene or derivative thereof. In the third step, the vapor may be contact with nitrogen gas to improve the yield of the cyclopentadiene or derivative thereof. |
