| Abstract: | dimethylnitrobenzene was synthesized from 2,4 dimethyl 6 nitroacetanil as the starting material with ethyl alcohol as the reductant.Spectral analytical and high efficiency liquid chromatographic analytical data have been given.It has been determined that the yield is highest in concentrated acid solutions when the acidity function H 0=-3.5 through solvation effect analysis of diazo denitrogenation reaction in acidic medium. |

| Keywords: | diazo reaction S N reaction solvation effect acidity function |
