Tetrabutyl Urea
Synonyms: TBU; N,N,N',N'-Tetra-n-butylurea; Tetra-n-buty lurea 1,1,3,3-Tetrabutylurea; Urea, N,N,N',N'-tetrabutyl- ;
Cas No.: 4559-86-8
Formula: C17H36N2O
Molecular weight: 284.4805
Applications:
Intermediate used as a reaction solvent in production of hydrogen peroxide. 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.
