    摘要: A new class of surfactants exhibits properties, which make the surfactants suitable for use in surfactant flooding for enhanced oil recovery. The surfactants have the formulaXA.sub.r ORSO.sub.3.sup.- M.sup.+ (I)where R is a hydrocarbon or hydroxyl-substituted hydrocarbon group with 2-6 carbon atoms; A is an oxyalkylene group having 2-4 carbon atoms; r is a number from 0-10, preferably 0-5 and most preferably 1-4; X is an hydroxyl group or hydroxyl and ether group containing hydrophobic group, which comprises 2-6, preferably 2-4 end groups containing 3-22 carbon atoms; and M is a cation, preferably a monovalent cation; or a C.sub.1-4 -alkyl ether thereof. A method for the manufacture of the surfactants are also enclosed.

    摘要: A process for isolating alkanesulfonates having a low alkali metal sulfate content and sulfuric acid from paraffin-sulfoxidation reaction mixtures with the aid of alcohols, the reaction mixture, freed from sulfur dioxide, being mixed in a sequence of five mixer/settler vessels with a C.sub.4 -C.sub.8 -alcohol and the amount of alkali metal hydroxide which is necessary for neutralization. The process is designed so that no alkali metal sulfate, but instead only sulfuric acid, is produced as a byproduct. Fewer alkali metal ions are thereby lost from the system, and the consumption of alkali metal hydroxide for neutralization is accordingly reduced.
