|
Abstract:
摘要： CO2作为一种碳资源,对其进行化学利用以达到减排目的,已成为目前科学研究热点之一。1,3,5-均三嗪三醇是一种CO2封存产品,开发其下游产品具有广阔前景。以1,3,5-均三嗪三醇(sym-triazinetriol, CA)与二乙烯三胺(diethylenetriamine, DETA)为原料,合成6-二乙烯三胺基-1,3,5-三嗪-2,4(1H,3H)-二酮。采用单因素法探讨了反应物摩尔比、反应时间、反应温度以及催化剂对产率的影响,由FT-IR、1H NMR与13C NMR等表征产物。反应最佳条件:CA与DETA摩尔比为1∶4,反应温度210 ℃,反应时间为4 h,催化剂为5A分子筛,产率为70.9%。
Abstract: 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%
