General description
Urea hydrogen peroxide (UHP) is an oxidizing agent consisting of urea and hydrogen peroxide. In the presence of carboxylic anhydrides, UHP is employed in a variety of oxidative conversions in anhydrous organic solvents. UHP is used as a hydrogen peroxide source in the oxidation reaction.
Application
Urea hydrogen peroxide can be used as an oxidizing agent:
- In the conversion of sulfides to sulfoxides or sulfones under solvent free condition.
- In the conversion of nitrogen heterocycles to their corresponding N-oxides.
- In the epoxidation of various alkene in combination with number of carboxylic anhydrides and disodium hydrogen phosphate in anhydrous organic solvents.
- In the Baeyer–Villiger oxidation reaction where in aldehydes and ketones undergo oxidation to produce esters and lactones using various peroxycarboxylic acids.
Features and Benefits
UHP is:
- Inexpensive.
- Stable.
- Easy handling reagent.

Reducing the emissions of soil fumigants such as 1,3-dichloropropene (1,3-D) is essential to protecting air quality. Although biochar is useful in reducing such emissions, biochar-adsorbed fumigants may desorb and cause secondary air pollution. This study investigated the degradation of 1,3-D
