Abstract

A fluidized-bed process for preparing hydrogen peroxide, C.sub.1 -C.sub.4 -monopercarboxylic acids and C.sub.4 -C.sub.18 -dipercarboxylic acid complexes in which a solution of hydrogen peroxide, a C.sub.1 -C.sub.4 -monopercarboxylic acid, a C.sub.4 -C.sub.18 -dipercarboxylic acid or a mixture thereof in water or carboxylic acids is applied to a pulverulent or pregranulated matrix and fluidized-bed drying takes place.
