Abstract:

The low temperature coal tar from Inner Mongolia was distillated effectively,and the distillate oil was separated to phenol oil and neutral oil through acid-base solution extraction.The chemical composition and structure of phenol oil and neutral oil were analyzed in a quantitative and qualitative way by GC-MS technology.The result shows that there are 40 kinds of compounds with mass fraction more than 0.1% in the phenol oil,mostly of which are phenol,alkyl phenol and naphthol; there are 104 kinds of compounds with mass fraction more than 0.1% in the neutral oil,mostly of which are alkene,alkane and naphthalene,etc..
