| Abstract: | Metal sodium was replaced by NaOH in the preparation of cyclopentadienylsodium(CPNa) via the reaction between NaOH and cyclopentadiene(CPD). The effects of mole ratio of NaOH/CPD, reaction temperature, and particle size of NaOH on reaction rate and yield were studied in detail. It was found that high reaction yield(95%97%) could be obtained with the new method under the following conditions: NaOH/CPD was 4/1(mole ratio), the particle size of NaOH was about 12mm and the reaction temperature was 0. |
