    Abstract: Improved process for the preparation of granular N-alkylammoniumacetonitrile salts Iwhere R1 to R5 are hydrogen or organic radicals, and Y- is a sulfate or hydrogensulfate anion,from an aqueous solution of the compound IIwhere R6 is C1- to C4-alkyl,which comprises evaporating this aqueous solution at a temperature of from 80° C. to 250° C. and a pressure of from 10 mbar to 2 bar to give a melt, then allowing the melt to solidify, where, during or following the evaporation, customary carrier materials and/or auxiliaries can be added, and the resulting solidified compound I is converted into the desired granular form.

    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.
