固体超强酸SO4 2-/TiO2催化合成尿囊素的研究
Synthesis of Allantoin by Solid Superacid SO42-/TiO2
摘要
Abstract
The allantoin was synthesized starting from carbamide and ethyl aldehydic acid by the solid superacid SO4 2-/TiO2 catalyst. It was found that the optiume experimental conditions were that TiO2 was immersed in 1 mol·L-1 H2SO4 for 12h and baked at 600℃ for 3h;the yield of the allantion could reach up to 57.4% under molar ratio of carbamide and ethyl aidehydic acid 3.5:1 ,amount of SO4 2- /TiO2 solid superacid catalyst of 9% ,the reaction temperature of 72℃～75℃ and reaction time of 3h.关键词
