纳米固体超强酸SO_4^(2-)/TiO_2催化合成尿囊素的研究

Study on Synthetic Allantion of Namometre Solid Sueracid SO_4^(2-)/TiO_2

以纳米固体超强酸SO24 /TiO2 为催化剂 ,以尿素和乙醛酸为原料合成了尿囊素 ,得到了最佳条件为 :尿素、乙醛酸摩尔比 3.5∶1 ,催化剂用量 6% ,反应温度 70～ 75℃ ,收率达 58.0 %

The allantion was synthesized from the material of carbamide and ethyl aldehydic acid through the catalyst of namometre solid superacide SO 4 2 /TiO 2. The proper technology parameters for the process are achieved: carbamide to ethyl aldehydic aid is 3.5:1, catalyst is 6%, the reaction temperature is 70～75℃, and the result is 58.0%.
