反応手順
Phosphotungstic acid reagent was prepared by refluxing a solution of 4 g sodium tungstate in 30 ml of H2O with 3.2 ml of 85% by weight orthophosphoric acid for 2 hours. The solution was then cooled to room temperature and diluted to 100 cc. Then 3.2 g of Li2SO4.H2O was added and mixed well. This liquid reagent material was incorporated into pods prepared as described in Example 1.
