Among the enhanced properties of the 1,3-dibromo-5,5-dimethylhydantoins described are their larger average particle sizes, their compactibility even though devoid of a binder, their excellent free-flowing and low-dust properties, and their more appealing aesthetic qualities, as compared to previously known 1,3-dibromo-5,5- dimethylhydantoins. These novel 1,3-dibromo- 5,5-dimethyl-hydantoins can be produced, for example, by concurrently feeding (i) an aqueous solution or slurry formed from an inorganic base and 5,5-dimethylhydantoin, and (ii) a brominating agent, in proportions such that each nitrogen atom is substituted by a bromine atom, thereby forming product which precipitates in an aqueous reaction mixture. The pH of the reaction mixture is maintained in the range of 5.5 to 8.5.

L'invention concerne du 1,3-dibromo-5,5-dimethyldantoine à propriétés améliorées. Parmi les propriétés des 1,3-dibromo-5,5-dimethyldantoines selon l'invention, on peut citer leurs granulométries moyennes supérieures, leur compatibilité même en l'absence de liant, leur excellentes propriétés de coulabilité et de dégagement de poussière faible et leurs qualités esthétiques plus attractives, comparativement au 1,3-dibromo-5,5-dimethyldantoine déjà connu. On peut préparer ces nouveaux 1,3-dibromo-5,5-dimethyldantoines, par exemple, en alimentant en même temps (i) une solution aqueuse ou une bouillie renfermant une base inorganique et un 5,5-dimethyldantoine, et (ii) un agent de bromation, dans des proportions telles que chaque atome d'azote est substitué par un atome de brome, formant ainsi un produit qui précipite dans un mélange réactionnel aqueux. Le Ph du mélange de réaction est maintenu dans la plage comprise entre 5,5 et 8,5.
