Реферат: ABSTRACT OF THE DISCLOSURE The production of organic hydrogen peroxide solutions which were practically anhydrous failed heretofore due either to a water content of the solutions which was too high or to an excessive loss of hydrogen peroxide by decomposition and when passing over as a distillate during the distillative drying operation. By selecting specific esters in combination with relatively high pressures in the azeotropic dehydration these disadvantages are avoided.
