    摘要: A process for the preparation of aralkyl hydroperoxides having the formula (I) is described ##STR1## in which n=1, 2 or 3, Ar means a phenyl group which can be substituted with halogen or one or more branched or straight chain alkyl groups with 1 to 5 C-atoms, or a naphthyl group, and each radical R.sup.1 and R.sup.2 means a low alkyl radical, the alkyl radicals R.sup.1 and R.sup.2 together having 2 to 4 carbon atoms, by reaction of aralkyl carbinols having the formula (II) ##STR2## in which Ar, R.sup.1, R.sup.2 and n have the meaning given for formula (I), with hydrogen peroxide under acid conditions, the reaction being carried out in the presence of an acid-combining agent. An alkali sulphate, ammonium sulphate, alkali hydrogen sulphate and/or ammonium hydrogen sulphate is used in preference as the acid-combining agent. Tert.aralkyl hydroperoxides can be prepared in high yield with a high purity in a simple and safe manner with this process.

    摘要: A process is described for preparing peroxyborate agglomerates having an active oxygen content of at least 14% by weight in which amorphous primary particles composed of peroxyborate prepared by a spray drying process are subjected to compacting pressing-agglomeration. Briquettes, compressed strips and tablets can be obtained which can be comminuted, if desired, to peroxyborate granules of desired particle size and bulk density. Advantageous, optionally colored, peroxyborate agglomerates, particularly peroxyborate granules are prepared. Preferred agglomerates and granules are composed of sodium peroxyborates.
