Multifunctional polymers containing polymerized units of

Multifunctional polymers, method for the production and use thereof

The invention relates to the use of compounds (A) with at least one structural unit of formula (I), wherein X represents groups of formula &#x2014;CR&#x2550;CR&#x2014; or a carbonyl group C&#x2550;O, Rand Rmeaning hydrogen or essentially organic radicals, Z means essentially organic radicals, n means a number from 0 to 3 and p means a number from 0 to 5, as UV absorbers with an affinity for textile fibres, for protecting the human skin from harmful UV radiation and for protecting dyed textile materials from fading.

UV absorbers with affinity for textile fiber

Method for the production of amines from epoxidized olefins

A process is provided for the epoxidation of olefins with percarboxylic acid in a reaction mixture consisting of an aqueous phase and an organic phase, the percarboxylic acid being formed in situ in the aqueous phase from hydrogen peroxide and a carboxylic acid or a carboxylic anhydride, and the olefins being dissolved in an organic solvent in the organic phase, wherein the epoxidation is carried out in several steps, each step being carried out with a fresh aqueous phase and the aqueous phase being separated off after each step.

Method of epoxidizing olefins

Method for producing (S,S)-N,N&prime;-ethylenediaminedisuccinic acid, analogous compounds or salts thereof

Fatty acid derivatives based on epoxidized unsaturated fatty acid esters or triglycerides and reacted with amines such as hydroxy- and/or amino-substituted hydrophilic amines or amino acids and/or with alkanols or with water on the epoxy group and/or the carboxylic ester groups are described. These fatty amides are suitable as surfactants in detergents and cleaners.

Fatty acid derivatives and their use as surfactants in detergents and cleaners

A process for preparing vicinal diols or polyols from an organic reaction mixture containing formic esters of vicinal diols or polyols, in which water is added to the reaction mixture, without addition of bases, and the formic esters are hydrolyzed in a subsequent thermal treatment, the aqueous formic acid is removed, and vicinal diols or polyols remain behind.
