1. tetracol phenixin is converted into a non-catalytic pyrolysis process for zellon, the method is with any one in monochloro methane, methane and Sweet natural gas, and chlorine and tetracol phenixin are the perchlorizing reaction that raw material carries out following formula (3) or (5):

  • CH 3cl+CCl 4+ Cl 2

    C 2cl 4+ 3HCl (3);

    Or CH 4+CCl 4+2Cl 2

    C 2Cl 4+4HCl (5),

    Wherein reaction pressure represents for 1.5kg/cm with absolute pressure 2~ 1.7kg/cm 2, Wherein tetracol phenixin is used as raw material and thinner simultaneously, temperature of reaction to be controlled at 550 DEG C ~ 700 DEG C.
