    • A process for the preparation of ureidoperoxycarboxylic acids of the formula ##STR1## in which x is the number 1 or 2,A,if x is 1,is hydrogen, C.sub.1 -C.sub.20 -alkyl, aryl, preferably phenyl, or haloaryl, preferably chlorophenyl, orif x is 2,is C.sub.1 -C.sub.20 -alkylene or arylene, preferably phenylene,B is a group of the formula ##STR2## in which n is a number from 1 to 20,m is the number 0, 1 or 2,R.sup.1 is C.sub.1 -C.sub.20 -alkyl andR.sup.2 is in each case hydrogen or C.sub.1 -C.sub.20 -alkyl, which comprises dissolving carbamoyllactams of the formula ##STR3## in which x, A and B have the abovementioned meanings, in a one- to six-fold, preferably a one- to three-fold, amount by weight of a strong catalyst acid, by then adding water in a one- to ten-fold molar excess, relative to the carbamoyllactam, to the solution of the carbamoyllactam in the catalyst acid and by heating the reaction mixture to form the ureidocarboxylic acid, by then adding to the reaction mixture an aqueous hydrogen peroxide solution in a one- to ten-fold, preferably a two- to four fold, molar excess per oxidizable carboxyl group of the ureidocarboxylic acid formed in the preceding reaction step, and by then precipitating the resulting ureidoperoxycarboxylic acid from the reaction mixture.These compounds are suitable as bleaches, oxidants and disinfectants.
    • 制备式A [NHCONHBCOOOH] x的脲基过氧羧酸的方法,其中x为数1或2,如果x为1,则为A,为C 1 -C 20烷基,芳基,优选苯基或卤代芳基 ,优选氯苯基,或如果x为2,则为C 1 -C 20亚烷基或亚芳基,优选亚苯基,B为下式的基团:其中n为1至20的数,m为数 0,1或2,R 1是C 1 -C 20烷基,R 2在各自的情况下是氢或C 1 -C 20 - 烷基,其包括将式(ⅩⅧ)的氨基甲酰基内酰胺溶解在其中x,A和B具有上述含义, 以强的催化剂酸的重量比为1至6倍,优选1至3倍,然后将相对于氨基甲酰基内酰胺的1至10倍摩尔过量的水加入到 催化剂中的氨基甲酰基内酰胺,并加热反应混合物形成脲基羧酸,然后向反应混合物中加入过氧化氢水溶液 在上述反应步骤中形成的脲基羧酸的每个可氧化羧基的摩尔过量为十倍,优选为二至四倍,然后从反应混合物中沉淀所得的脲基过氧羧酸。 这些化合物适合作为漂白剂,氧化剂和消毒剂。
