Chlorobenzene is analyzed by gas chromatography (Shimadzu
GC2010 equipped with a flame ionization detector), the packed column
is HP-5 (30m×0.32 mm). The injector and detector are set at
200 and 220 ◦C, respectively. The column works from 40 to 60 ◦C
at the speed of 2 ◦C/min. Flame gases are air at 400cm3/min and
hydrogen at 43cm3/min. Nitrogen is the carrier gas.
