Using Tetrabutylurea as one kind of solvent has several advantages: oxanthranol has higher solubility in it ; alkali-resisting and high temperature resistance can enhance using times and reduce consumption at the same time. In addition, Tetrabutylurea’s high boiling point is contributed to dehydration process of hydrogen peroxide synthesizing.
