EMULSIFIER, WATER-IN-OIL EMULSION, EXPLOSIVE EMULSION, AND EMULSIFIER PREPARATION PROCEDURE Russian patent published in 2001 - IPC

FIELD: emulsifiers. SUBSTANCE: emulsifier contains mixture of esters prepared via interaction of polyol, in particular sorbitol and/or mono-, oligo-, or polysaccharide, with mono- or polybasic acid with hydrocarbon chain containing 2 to 50 carbon atoms and optionally including branched, aromatic, or another cyclic carbon skeleton of the polymer or oligomer type. Water-in-oil emulsion contains 0.1 to 3 wt.% of emulsifier and its water part contains nitrate salts in relatively high concentration. Explosive emulsion further contains coemulsifier, organic acid, gas-forming agent up to 5% and ammonium nitrate. Emulsion is applied both in formed and in gas-expanded state. Emulsifier is prepared by consecutively mixing reagents while gradually raising temperature from 60 to 240 C, whereupon mixture is cooled to temperature below 60 C. EFFECT: increased stability of products. 16 cl, 1 tbl
