Abstract: Stabilized water-containing sodium dithionite formulations which have been rendered alkaline have the consistency of a pumpable paste. They additionally contain readily soluble sodium salts and/or potassium salts which are inert to sodium dithionite and whose water-solubility at 20 DEG C. exceeds 500 g/l. These salts are present in the aqueous phase in an amount of not less than 200 g/l. The pastes are useful reducing agents.

Abstract: Production of an alkylene oxide (A) involves (a) epoxidation of the corresponding olefin with aromatic peroxycarboxylic acid (I) and separation of the resultant aromatic carboxylic acid (II), (b) hydrogenation of (II) to the corresponding aldehyde (III) and (c) oxidation of (III) with oxygen (or gas containing oxygen) to (I), which is re-used for the epoxidation. The novel feature is that (i) (II) and/or (III) lost in the cycle is replaced by compounds obtained by oxidation of the parent alkyl-aromatics, (ii) phenolic by-products in the aldehydes are removed before stage (c) or (iii), if the olefin has 2-6C, it is prepared by dehydrogenation of a corresponding 2-6C hydrocarbon.
