Separation of Nitrotoluene Derivatives by Gas Chromatography

In this paper various factors that effected on separation of mono and di substituted nitro toluene compounds was investigated by gas chromatography method and optimum separation condition was reported for 2-nitrotolouen (2NT), 4-nitrotolouen (4NT), 2,3-dinitrotolouen (2,3DNT), 2,4-dinitrotolouen (2,4DNT), 2,6-dinitrotolouen (2,6DNT) and 3,4-dinitrotolouen (3,4DNT) compounds. Optimum carrier gas flow rate and injection volume was 20-30 ml.min-1 and 0.3 l, respectively. Isothermal separation method wasn’t accepted for given good results and then programming mode (T1=80 OC, t1=6S, scan rate=30, T2=240, t2=6s) was used.
