| Abstract: | The synthesis of the third comonomer of Kevlar 1414, p,p'-diaminophenylpiperazine was discussed and the synthesis of its intermediate, p,p'-dinitrophenylpiperazine was studied systematically. The characteristic of synthesizing p,p'-dinitrophenylpiperazine is the addition of calcium hydride, raising the productivity up to 82.3%, far higher than that reported in the previous papers (57.9%). The process of the synthetic reaction was also discussed in the present paper. |
