As a carbon resource, it has become one of the hot spots at present through the chemical utilization of CO2 to achieve emission reduction purposes. Sym-triazinetriol is kind of CO2 sequestration products, and it has broad prospects to develop its downstream products. In this paper, synthesis of 6-divinyl three amine-1,3,5-triazine base-2,4(1H,3H)-diketone by diethylenetriamine(DETA)and Sym-triazinetriol(CA)was studied. The effects of molar ratio, reaction time, reaction temperature and catalyst on the yields were investigated by single-factor method. Then, the product was characterized by IR, 1H NMR and 13C NMR. The optimum conditions were as follows: the molar ratio of CA to DETA was 1∶4, the reaction temperature was 210 ℃, the reaction time was 4 h, the catalyst was 5A molecular sieve. The yield of product can reach 70.9%.
