Abstract: Epoxides are prepared by reaction of compounds containing olefinic unsaturation, for example .alpha.-olefins, terpenes and steroids, with an aliphatic diperoxydicarboxylic acid. The diperoxydicarboxylic acid contains 2 to 16 carbon atoms and suitably at least 6 carbon atoms. The process gives a good epoxidation process and does not give rise to byproduct formation.

Abstract: Stabilized diperoxydicarboxylic acids are prepared in which diperoxydicarboxylic acids are mixed with sodium sulfate produced in the process to yield improved diperoxydicarboxylic acid granules having good chemical stability despite a high impurity content, safe handling, low bulk density and high abrasion resistance.

Abstract: The invention is directed to a process for hte production of water insoluble peroxycarboxylic acids in which the carboxylic acid is suspended in the reaction mixture and reacted with hydrogen peroxide in the presence of pyridine-2,6-dicarboxylic acid.

Abstract: A process for the preparation of agglomerates containing diperoxydodecanedioic acid and a water-impermeable material, e.g. lauric acid, which process comprises the successive steps of agitating an aqueous suspension of the peroxy acid in the presence of the water-impermeable material and above the melting point thereof, cooling the suspension of the agglomerated particles thus obtained to a temperature at which the water-impermeable material turns solid, and isolating the resulting agglomerates. The agglomerates obtained are suitable for use as bleaching agent.

Abstract: In order to safely prepare peracetic acid in an organic solvent, the bottom is maintained in a certain stationary state during the preparation of aqueous peracetic acid, whereupon the vapor current of peracetic acid, acetic acid and water is absorbed with an organic phosphate with 3-30 carbon atoms. The solution obtained in this manner can be transferred by means of desorption with a low-boiling compound, e.g. an alkyl ester, into this lower-boiling solvent.
