Abstract (en)
[origin: DE10032829A1] 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.
