| Abstract: |
| The carbon black was modified by gas-solid stirring chlorination，and the chlorine content in the chlorinated carbon black as a function of the temperature and time of reaction，and the chlorine flow was investigated with the binary regressive analysis.The results showed that the suitable reaction conditions were as follows:temperature 130 ℃，time 1.5～2 h，chlorine flow 554
mL·min-1；the nitrogen-filled treatment could be used instead of the water flushing treatment for the post-treatment of chlorinated carbon black；it was indicated by SEM that the agg regated structure of the chlorinated carbon black changed，but the chain structure didnt. |
