Abstract: In the process described, alkoxylation of compounds containing active hydrogen atoms using antimony pentahalides as catalyst is carried out such that first a catalyst premix is prepared by dissolving antimony pentahalide in a portion of the amount of the compound to be alkoxylated while maintaining a maximum temperature of 60 DEG C and a maximum antimony pentahalide concentration of 30 mol%, the catalyst premix prepared or a portion thereof is combined as the catalyst component with the remaining amount of the compound to be alkoxylated, and the starting mixture thus obtained is reacted with the alkylene oxide.

Abstract: The new compounds consist essentially of ethylene oxide/propylene oxide block polymer units and oxyalkyleneated alkylphenol/aldehyde resin units, which are linked by methylene groups. They are prepared by reacting a block polymer of ethylene oxide and propylene oxide and an oxyalkyleneated alkylphenol/aldehyde resin with formaldehyde. The new compounds constitute especially advantageous breaking agents for petroleum.

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 invention relates to alkoxylation product mixtures of the formula I having a narrow alkoxyl distribution (I) where R is the radical of an organic compound containing at least one active hydrogen atom, m is an integer from 1 up to the number of active hydrogen atoms in the organic compound, x and y in each case are the average molar number of ethylene oxide or propylene oxide units and independently of one another are an integer from 2 to 10 and the individual alkoxylation units of the alkoxylation product mixture in each case at most have a degree of alkoxylation of 18% by weight. The invention further relates to a process for their preparation, and their use.
