Abstract
The pathway of TCNE and TCNQ interaction with coal was investigated based on the spectrum properties of TCNE and TCNQ in NMP. It was found that TCNE and TCNQ do not interact with coal directly. Instead, TCNE and TCNQ form 1,1,2,3,3-pentacy anopenide anion and TCNQ radical anion first, respectively, then the anions interact with coal.
