DESCRIPTION

Tetrabutylurea

Chemical name: 1,1,3,3-tetrabutylurea

Customs Code: 2924199090

It is a uniform, transparent and colorless oily liquid with slightly higher viscosity than water. It is mainly used as hydrogen anthraquinone solvent in the new process of producing hydrogen peroxide by anthraquinone method. Compared with trioctyl phosphate, hydroanthraquinone has higher solubility; The distribution coefficient of H2O2 in two phases is large; Tetrabutyl urea has the advantages of large density difference with water and large surface tension.
