Description
Tetrabutylurea is a chemical substance, a transparent or slightly yellowish liquid with a slightly higher viscosity than water. Compared with trioctyl phosphate, it has the advantages of higher solubility of hydroanthraquinone, higher distribution coefficient of H2O2 in two phases, larger density difference between tetrabutylurea and water, and higher surface tension.
