    Abstract: The production of hydrogen peroxide, C1 to C4 monopercarboxylic acid and C4 to C18 dipercarboxylic acid complexes by the fluidised bed process by the addition of a solution of hydrogen peroxide, C1 to C4 monopercarboxylic acid, C4 to C18 dipercarboxylic acid or a mixture thereof in water or carboxylic acids to a powdered or pregranulated matrix in or outside the fluidised bed and simultaneously or successively drying of the fluidised bed, in which use is made as a matrix of: A) N-vinyl caprolactam homopolymer, B) N-vinyl caprolactam copolymers with N-vinyl pyrrolidone, N-vinyl imidazole, acryl or methacryl amidopropyl-3-sulphonic acid, acrylic or methacrylic acid or mixtures thereof as comonomers in the proportion by weight of N-vinyl caprolactam to comonomers of 20:1 to 1:20, C) N-vinyl pyrrolidone copolymer with N-vinyl imidazole, acrylic or methacrylic acid or mixtures thereof as comonomers in the proportion by weight of N-vinyl pyrrolidone to comonomers of 20:1 to 1:20, D) N-vinyl imidazole homopolymers which may be substituted in the heterocyclic ring by up to three C1 to C4 alkyl radicals and may be present in C1 to C4 alkyl N-quaternised form, E) mixtures of monosaccharides, oligosaccharides, polysaccharides or derivatives thereof with the polymers A to D in the proportion by weight of 1:99 to 90:10, F) mixtures of monosaccharides, oligosaccharides, starches, starch decomposition products or derivatives thereof with N-vinyl pyrrolidone homopolymers in the proportion by weight of 1:99 to 90:10, G) mixtures of trehalose, saccharose, glucose, α or β or η cyclodextrins or derivatives of said cyclodextrins or mixtures thereof with polymers A to D or with N-vinyl pyrrolidone homopolymers in the proportion by weight of 1:99 to 100:0 or H) in the case of C1 to C4 monopercarboxylic acid and C4 to C18 dipercarboxylic acid complexes, N-vinyl pyrrolidone homopolymers.
