Abstract:

A method for determining content of aromatics in mixed benzene by capillary gas chromatography has been developed. The method, using FFAP capillary column with program temperature and split injection mode, has separated at least 130 contents from mixed benzene. 29 kinds of aromatics and some non-aromatics such as paraffin, double-ring dienes are identified by MS. The results show that alkyl benzene, olefinic benzene, indene, naphthalene and its derivatives are the main aromatic content in mixed benzene.
