    Abstract: The invention relates to ampiphilic compounds and mixtures thereof, methods for production and use thereof in oil-in-water emulsions. The compounds are made up of a lipophilic and a hydrophilic part. Both parts are linked togeth er by means of a linker derived from succinic acid. The lipophilic part is form ed from a polyisobutylene group with a number-average molecular weight Mn of 30 0 to 10000. The hydrophilic part is characterised in preferably having two polyethylene glycol chains which can be produced by reaction of OH, -N(H)- and/or -NH2 with ethylene oxide. A globular non-linear structure for the hydrophilic part is thus achieved, such that the hydrophilic character of sa id compounds predominates and makes the same particularly suitable for oil-in- water emulsions. The invention further relates to preparations for the treatment of metal surfaces, in particular for corrosion protection, comprising at least one said compound, at least one solvent which can dissolve, disperse or emulsify said compound(s) and optionally further components. Furthermore, a method for treatment of metal surfaces by bringin g the metal surface into contact with said preparation and coated metal surfac es are disclosed.

    Abstract: Production of polyalkenyl succinimide products (I) by reacting a polyalkene with maleic acid, maleic anhydride or a functional derivative thereof and reacting the resulting polyalkenyl succinic anhydride (II) with an oligo- or polyamine (III). Production of polyalkenyl succinimide products (I) by reacting a polyalkene with maleic acid, maleic anhydride or a functional derivative thereof and reacting the resulting polyalkenyl succinic anhydride (II) with an oligo- or polyamine (III) comprises either (a) reacting (II) with an alcohol or phenol and reacting the product (not isolated) with (III); or (b) reacting (II) with (III) in the presence of an alcohol or phenol; and (c) optionally removing the alcohol or phenol. Independent claims are also included for the following: (1) polyalkenyl succinimide products produced by a process as above; (2) polyalkenyl succinimide products that are produced from a polyalkenyl succinic anhydride and an oligo- or polyamine and contain no more than 30 wt.% of the corresponding polyalkenyl succinamide; (3) polyisobutenyl succinimide products that contain no more than 30 wt.% of the corresponding polyisobutenyl succinamide and are produced from (a) a polyisobutene with a number-average molecular weight (Mn) of 500-10,000 and a terminal double bond content of more than 50 mole%; (b) maleic anhydride; and (c) either a linear, branched, cyclic or cyclic branched alkylene polyamine with 1-10 carbon atoms in each alkylene group and 2-12 nitrogen atoms, at least one of which is present as a primary amine group, or an oligo- or polyamine of formula (IIIa); (4) polyisobutenyl succinic acid monoester products produced from (a) a polyisobutene with a Mn of 500-10,000 and a terminal double bond content of more than 50 mole%; (b) maleic anhydride; and (c) alcohols of formula (IV) or phenols; (5) diesel and gasoline fuel additive packages comprising the products of (1)-(3) and optionally other additives; and (6) lubricant compositions comprising the products of (1)-(3) and optionally other additives. R = 1-16C linear, branched, cyclic or branched cyclic alkyl; x, y = 1-5; z = 0-8.
