Abstract
Regeneration procedure of the spent working solutions of the cyclical processes of preparation of hydrogen peroxide to anthraquinone, which consists of two phases, according to which the solvents are removed in the course of a first distillation, at a maximum pressure equal to at atmospheric pressure, and then the quinones and monoanthracene "light degraded products" are separated in the course of a second distillation carried out at a lower pressure, and in addition all the distilled products are used again as a new working solution, characterized in that the vapors from the second distillation are condensed on a constantly renewed liquid film of cold solvent, said film of solvent coming from the condensable vapors of the first distillation.
