Abstract: In the process described for the preparation of alkoxylates having a narrow distribution of homologs by reaction of compounds containing at least one hydroxyl group with alkylene oxide, complex compounds of antimony pentahalide with a special Lewis base are used as the catalysts. Alkoxylates having a narrow distribution of homologs and good color quality are obtained at a high conversion.

Abstract: The urethanes described are synthesized from aliphatic fluoro alcohols, triisocyanate and a carboxylic acid. They are prepared by reaction of the aliphatic fluoro alcohol with the triisocyanate to give the fluoro alcohol/triisocyanate adduct and by reaction of this adduct with the carboxylic acid. The new urethanes are preferably used for the finishing of textiles for the purpose of achieving water, oil and soil repellency.

Abstract: The novel glycidyl ether addition products are obtained by esterification of a diol compound, selected from the group comprising linear oxyalkylates and other amine-free aliphatic diols, and an addition compound of polyether block polymers and glycidyl ethers with dicarboxylic acids. They are advantageously employed for demulsifying crude oil emulsions.

Abstract: The invention relates to the use of alkoxylated fatty amines and fatty amines of the general formula (I), where A is a radical of the formula (II)-(V) with R = C6-C22-alkyl, x is a number from 5 to 40, y is a number from 5 to 70 and that z is equal to 0-70% by weight of ethylene oxide, relative to compounds of the formula (I) with x ethylene oxide units and y propylene oxide units, as demulsifiers, corrosion inhibitors and/or pour point depressants in crude oils. There are radicals of the general formula (I) without A all the free valencies of the nitrogen atoms of the formulae (II) to (V). The compounds of the formula (I) are prepared by reacting amines of the formulae (II) to (V) with ethylene oxide and propylene oxide, with addition of bases such as alkali metal hydroxides.
