ABSTRACT:
The invention concerns a method for producing hydrogen peroxide using a process based on anthraquinone derivatives. According to the invention the solvent system of the working solution in said process contains carbamate having a general formula ##STR1## where groups R.sup.1 and R.sup.2, which can be the same or different ones, are a hydrogen atom or a hydrocarbon group and R.sup.3 is a hydrocarbon group,
whereby the groups R.sup.1, R.sup.2 and R.sup.3 can optionally be part of a cyclic structure and/or substituted by groups which are inert to the process.
