Abstract: The invention relates to a method of epoxidizing olefins with percarboxylic acid in a reaction mixture consisting of an aqueous phase and an organic phase. According to said method, the percarboxylic acid in the aqueous phase is formed in situ from hydrogen peroxide and a carboxylic acid or a carboxylic acid anhydride and the olefins in the organic phase are dissolved in an organic solvent. The epoxidation is carried out in several steps. Each step is carried out with a fresh aqueous phase each and after each step the aqueous phase is removed.

Abstract: The use is disclosed of a compound having the general formula (I), as well as its alkali salts, as scaling inhibitors and/or (co)-builders. In the formula (I), R' stands for hydrogen and R and R' independently represent branched or non-branched aliphatic C4-28 radicals which can contain one or several double C-C and/or triple C-C bonds. Radicals R and R' may be interrupted by one or more non-adjacent oxygen atoms, NH groups and/or N-C1-4-alkyl groups, and may be substituted by one or more hydroxyl groups, primary amino groups and/or secondary C1-4-alkylamino groups; or radicals R and R' are hydrogen atoms and radical R' has the above-mentioned meaning; or R' has the meaning given above for R' and R and R' are hydrogen atoms.
