| Abstract: | Online Infrared spectrum was used for monitoring the reaction process of synthesizing 3,5-diamino-1,2,4-triazole(DAT).The obtained data matrix of IR was analyzed by multivariate curve resolution-alternating least squares method(MCR-ALS) and reasonable mechanism was deduced.The water was used as the background for reaction,then cyanoguanidine and hydrazine dihydrochloride were added in turn,which was detected by IR probe.The concentration profiles and spectra of reactants,intermediates and product were deter... |
