In order to obtain green and insensitive high energy explosives,50 grams-scale synthetic method of dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate(TKX-50)was investigated. The key intermediate of 5,5′-bistetrazole-1,1′-diol dihydrate(1,1′-BTO)was synthesized through oximation,chlorination,azidation and cyclization from glyoxal. TKX-50 was successfully obtained from the reaction of 1,1-BTD with hydroxylamine aqueous solution. The product was characterized by 1H NMR,IR,MS,DSC and element analysis. In the preparation process of TKX-50 from 1,1′-BTO,the influence of molar ratio of reactants,reaction time and temperature on the yield of TKX-50 were studied. The optimal conditions of the process were determined:when the reaction was operated at 80 ℃ for 1h with the molar ratio of n(1,1′-BTO)∶ n(NH2OH·HCl)∶ n(NaOH)= 1 ∶ 2.2 ∶ 2.2. The yield could achieve in 80 . 1%. The total yield of the synthetic route is 41 . 5 %. The technology is valuable for the preparation of TKX-50 in large scale.
