A process for removing sulfuric acid from the reaction mixture obtained in the sulfoxidation of paraffins, which comprises adding an organic amine sulfate to the reaction mixture and removing the phase consisting of water and sulfuric acid which thereby separates out, adding to the remaining phase containing alkanesulfonic acid and alkanesulfonic acid amine salt an amount of an alkali metal hydroxide sufficient to convert the alkanesulfonic acid and the alkanesulfonic acid amine salt into the alkali metal alkanesulfonate, the organic amine being liberated, removing the paraffin from this mixture, together with the free organic amine, by steam distillation, removing the free organic amine from the paraffin by extraction with sulfuric acid and employing the resulting organic amine sulfate again at the start of the whole process for removing the sulfuric acid.

Addition products obtained by reaction of triethanolamine condensation products of the formula 1, ##STR1## wherein n is intended to denote a number from 1 to 3, with bisglycidyl ethers of the formula 2, ##STR2## wherein R.sup.1 can be identical or different and denote hydrogen, C.sub.1 -C.sub.4 -alkyl or halogen, in particular chlorine, A denotes a direct bond, a sulfonyl or cyclohexyl group or a group of the formula ##STR3## wherein R.sup.2 denotes hydrogen, methyl or phenyl and a denotes a whole number from 0 to 10, and their use as demulsifiers for oil-water emulsions, as lubricants and as paper auxiliaries.

Addition products from triethanolamine condensation products and

New bisesters of alkenylsuccinic acids and ethylene oxide/propylene oxide block polymers, which are obtained by reaction of alkenylsuccinic anhydride of the Formula 1 ##STR1## wherein R denotes branched or unbranched C.sub.2 -C.sub.20 alkyl, with an ethylene oxide/propylene oxide block polymer of the Formula 2 ##STR2## wherein R denotes methyl or ethyl, n and m are numbers selected such that the polyethylene oxide contribution to the total molecule is 5 to 80% of the molecular weight and p is a number from 10 to 70, and their use as demulsifiers for oil-water emulsions, as corrosion-protective agents and as dispersants for dyestuffs.
