What Is Tetrabutylurea?
Tetrabutylurea (TBU), CAS 4559-86-8, is a substituted urea solvent used in the working solution of the anthraquinone process for hydrogen peroxide, where it dissolves the hydrogenated form of the working compound.
The TDS specifies at least 99.5% TBU, with di-n-butylamine and water each at most 0.10%. Density is given at 20°C, colour on the platinum-cobalt scale and interfacial tension against water at 20°C.
TBU is a combustible liquid with a closed-cup flash point of 93°C. It is not regulated as dangerous goods under IMDG or IATA; under US DOT it is listed as NA 1993, combustible liquid. Keep it away from ignition sources.
As a tetrabutylurea supplier and exporter in China, ZXCHEM packs TBU in 170 kg steel drums.

Tetrabutylurea Applications
Hydrogen peroxide working solutions
Polar solvent in anthraquinone-process working solutions, used with an aromatic solvent. Solubility of the working compound and phase behaviour are checked against the plant solvent system.
Industrial solvent systems
Solvent for chemical and formulation systems that need a high-boiling polar solvent. Solubility, stability and material compatibility are tested under the intended conditions.
Reaction medium
Reaction medium for industrial synthesis trials. Reaction compatibility, thermal conditions and safe handling are checked before scale-up.
