用光度法研究了仿生理条件下麻黄碱 (伪麻黄碱 )和水杨醛缩合产物唑烷的水解反应过程。证实了它们的水解均为一级反应 ,半衰期分别为 34s和 8.9s,水解反应速率与它们自身结构相关
The hydrolysis reaction of ephedrine (pseudoephedrine) and the condensation product of salicylaldehyde and oxazolidine was studied by photometric method. Confirmed that their hydrolysis are the first-order reaction, half-life were 34s and 8.9s, the hydrolysis reaction rate and their own structure
