    Abstract: Polyisobutenylphenol-containing Mannich adducts are prepared by a) alkylation of a phenol with highly reactive polyisobutene at below about 50° C. in the presence of an alkylation catalyst; b) reaction of the reaction product from a) with formaldehyde, an oligomer or a polymer of formaldehyde and at least one amine which has at least one secondary amino function and no primary amino function, or c) reaction of the reaction product from a) with at least one adduct of at least one amine which has at least one secondary or primary amino function and formaldehyde, an oligomer of formaldehyde, a polymer of formaldehyde or a formaldehyde equivalent, and are used as detergent additives in fuel and lubricant compositions, and additive concentrates, fuel compositions and lubricant compositions contain these Mannich adducts.

    Abstract: Polyisobutenylphenols are prepared by alkylating an aromatic hydroxy compound with substantially monoethylenically unsaturated and substantially homopolymeric polyisobutenes in the presence of a Lewis acid alkylation catalyst by a process in which the polyisobutenes have a beta double bond content of at least 35 mol %.

    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 invention relates to a method for producing Mannich adducts that contain polyisobutylene phenol by: a) alkylating a phenol with highly-reactive polyisobutylene at a temperature lower than approximately 50 DEG C and in the presence of an alkylation catalyst; b) reacting the reaction product from a) with formaldehyde, an oligomer or with a polymer of the formaldehyde and with at least one amine, which has at least one secondary amino function and does not have any primary amino function; or c) reacting the reaction product from a) with at least one adduct consisting of at least one amine, which has at least one secondary or primary amino function, and with formaldehyde, an oligomer of the formaldehyde, a polymer of the formaldehyde or with a formaldehyde equivalent. The invention also relates to Mannich adducts that can be obtained by using this method, to the use of the Mannich adducts as detergent additives in fuel compositions and lubricant compositions, and to additive concentrates, fuel compositions and lubricant compositions containing these Mannich adducts.
