Amino-3-dodecyl-1,2,3-triazolium nitrate was synthesized through 4 steps including addition-elimina-tion,cyclization,alkylation and double replacement reaction by using glyoxal,hydrazine and bromododecane.The products were characterized by NMR,FT-IR and MS.The reaction conditions of addition-elimination,cyclization and alkylation were explored and optimized.The optimal conditions for each step of the reactions are as follows:In addition-elimination reaction,n(hydrazine hydrate)n(glyoxal)n(methanol)=319,70℃for 5 h with a yield of 90.3%;In cycliza-tion reaction,m(MnO2)m(glyoxal bishydrazone)=21,20℃ for 3 h with a yield of 88.2%;In alkylation reaction, n(1-amino-1,2,3-triazole)n(bromododecane)=11.5,80℃ for 40 h with a yield of 64.5%.The fourth step is a simple metathesis reaction with a high yield,in which the reaction time is 3.5h and the yield is 80.4%.The total yield of target product is 41.3%.
