| Abstract: | Phenylhydrazine is prepared with high purity and high yield by improving the existing process. The purity of phenylhydrazine is higher than 99%(GC) ,the yield is over 75%,and the content of benzidine is less than 0 0015%(HPLC),aniline fewer than 0 1%(HPLC), and phenol no more than 0 05%(HPLC). The total yield of phenylhydrazine is increased from 70% to 75%. |
