Calculation of a specific rate constant (k) and activation energy (Ea) of 18F-labeling reaction is important to obtain objective data. However, it has never been tried, because short time heating required for the calculation of the parameters was difficult. In the present study, we could calculate the parameters using combination of coat-capture–elution method (Aerts et al.) and microfluidic processes
18 F标记反应的比速率常数(k)和活化能(E a)的计算对于获得客观数据很重要。但是,从未尝试过,因为难以快速计算参数所需的加热时间。在本研究中,我们可以结合使用外套捕获-洗脱方法(Aerts等人)和微流体过程来计算参数。在丙酮,MeCN和t- BuOH中获得的Ts-萘酚的E a值分别为5.83、8.98和13.54 kcal / mol,在相同溶剂中获得的Ms-萘酚的E a值分别为5.81、8.16和19.34 kcal / mol,分别。这些参数的计算对于设置[18 F]氟化程序,用于开发新的前体。
