METHOD OF PRODUCING OIL-SOLUBLE POLYMER EMULSIFIER Russian patent published in 2000 - IPC

FIELD: methods of production of oil-soluble polymer emulsifiers based on alkenyl-succinic anhydride applicable in production of emulsion industrial explosives. SUBSTANCE: method consists in condensation of anhydride and alkanol-amine or polyamine with agitation in medium of industrial oil and heating in current of inert gas, withdrawal of separating water and filtration from impurities. Components are taken in molar ratio of alkenyl-succinic anhydride and triethanolamine of 1: (0.19-0.3) or alkenyl-succinic anhydride and polyamine in molar ratio of 1:(0.19-0.3). Polyamine is used in the form of still bottoms of production of ethylenediamine or polyethylene-polyamine. EFFECT: higher yield of product and reduced cost price. 2 cl, 1 tbl
