| Abstract: |
| The total volatile organic compounds（TVOCs） of carbon black SP5000（K），N500（K），N500
（Q） and N500（O） produced by different manufacturers（referred to as K，Q，O respectively） were analyzed
by thermal desorption method using air bags. The results showed that，the order of the TVOCs content of 4
carbon black products from high to low was carbon black SP5000（K），N500（K），N500（Q） and N500（O），
and the TVOCs content of carbon black SP5000（K） was more than 60 times higher than that of carbon black
N500（O）. The order of the types of organic compounds from many to least in the TVOCs was carbon black
N500（K），N500（Q）/N500（O） and SP5000（K），and there were 18 more organic compounds in the TVOCs
of carbon black N500（K） than that of carbon black SP5000（K）. The order of the content of benzene series
in the TVOCs from large to small was carbon black N500（K），N500（Q），SP5000（K） and N500（O），and the
benzene series content in the TVOCs of carbon black N500（K） was 200 times more than that of carbon black
N500（O）. The organic compound having the highest content in the TVOCs of carbon black SP5000（K） and
N500（O） was butyl formate，and the organic compound having the highest content in the TVOCs of carbon
black N500（K） and N500（Q） was phenol. |
