    Abstract: The invention relates to compounds, especially compounds based on polyisobutylenamines, which are suitable for emulsifiers for water-in-oil emulsions. The invention also relates to a method for the production of said compounds and to the use thereof, mainly as additives for fuels and lubricants. The compounds according to the invention are compounds of genera l formula (I), wherein R1 represents a C1-C8-alkylene or a C2-C8-alkenylene optionally substituted with C1 -C12-alkyl; R2 represents a linear or branche d C8-C350-alkyl or a C8-C350-alkenyl; R3 and R4 independently represent H, methyl or ethyl and together do not have more than 2 C atoms; R5 represents H, M+, SO3H, SO3- M+, PO3H, PO3-M+ and C(O)R7, wherein M+ represents NH4+, an alkaline metal ion or 0.5 earth alkaline metal ions; R7 represents one linea r C2- to C1O- hydrocarbon radical substituted with at least one hydrophilic group, and y and z independently represent whole numbers from 0 to 50, where in R5 = H if y = 0 and R6 = H if z = 0.

    Abstract: The invention relates to a method for removing aromatic hydroxy compounds from fluids that contain an aromatic hydroxy compound and at least one ring alkylation product. The method is characterized by contacting the fluid with an anion exchanger in the hydroxyl form, the aromatic hydroxy compound having a higher affinity to the anion exchanger than its ring alkylation products. The fluid from which the aromatic hydroxy compounds have been removed is then removed from the anion exchanger. The fluid used is for example a crude reaction mixture derived from the alkylation of aromatic hydroxy compounds.

    Abstract: In an explosive composition comprising an emulsifier in a water-in-oil emulsion, the emulsifier is a Mannich adduct (I) of (a) a mono- or polycyclic mono- to penta-hydroxy-aromatic compound (II), mono-, di- or tri-substituted by 6-400C alk(en)yl(aryl), (b) formaldehyde or its oligomer or polymer and (c) a nitrogen compound such as an amine with primary or secondary amine function(s) and ammonia. In an explosive composition comprising an emulsifier in a water-in-oil emulsion, the emulsifier is a Mannich adduct (I) of (a) a hydrocarbyl-substituted hydroxyaromatic compound of formula (II), (b) formaldehyde or its oligomer or polymer and (c) a nitrogen (N) compound selected from an amine with primary or secondary amine function(s) and ammonia. (R1>)nAr(OH)x (II) R1>a hydrocarbyl group, selected from linear or branched 6-400 carbon (C) alkyl, 6-400C alkenyl, 6-400C alkenyl-aryl or 6-400C alkyl-aryl; Ar : a mono- or polycyclic, optionally substituted aromatic ring; n : 1, 2 or 3; x : 1-5. An independent claim is also included for the production of the explosive composition by dissolving (I) in an organic liquid forming the oil phase, warming this solution if necessary and emulsifying an optionally warmed aqueous phase containing an inorganic oxidant.

    Abstract: The present invention relates to the use of linear or star-shaped block copolymers which are provided with at least one polymer block A which mainly consists of isobutene units and at least two polymer blocks B which mainly consist of units that are derived from vinyl aromatic monomers. Said block copolymers are used as elastic sealing material. The invention especially relates to the use of such sealing materials for sealing the edge joints in insulating glass panes and insulating glass panes which are provided with a flexible edge-joint sealing which contains one of the block copolymers.
