Dinitroaromatics compounds such as 1, 2- dinitrobenzene (1, 2-DNB) of BDH chemicals was purified by crystallizing it from ethanol (m.p found116C: reported 116.5C) and 1, 3- dinitrobenzene (1,3-DNB) of HOPKIN and WILLIAMS Ltd.
After running the blank an appropriate amount of compound (1,2- DNB, 1,3- DNB and 1,4- DNB) was added in the TBAP solution to make (dinitrobenzene) solution in the concentrations rangefrom 1A-10-4M - 1A-10-3M.
Summary: Cyclic voltammetric method has been employed to investigate the protonation of anion radicals of 1,2-, 1,3-, and 1,4- dinitrobenzenes in Hexamethylphosphortriamide (HMPA) in the temperature range 5C, 15C, 25C and 35C.
