Abstract
A process for the production of hydrogen peroxide according to the anthraquinone process. According to the process certain cyclic urea derivatives are used as solvents, and particularly as solvents for anthrahydroquinones. The cyclic urea derivatives whcih can be N,N'-dialkyl substituted alkyleneurea, give a very good solubility for anthrahydroquinones and also for anthraquinones. The compounds can be used as the sole solvent at the production of hydrogen peroxide or in combination with conventionally used solvents such as hydrocarbons.
