FIELD: chemistry.
SUBSTANCE: invention relates to emulsion explosives. The method of preparing an emulsifier for production of emulsion explosives based on products of condensation of polyisobutylene succinic anhydrides with alkanol amines dissolved in industrial oil involves esterification in two steps. At the first esterification step, alkenyl succinic anhydride is reacted with dimethylethanolamine in the presence of industrial oil and pinene or camphene, obtaining an intermediate product in form of a 50% solution of ether amides in industrial oil. At the second esterification step, while heating and stirring, the obtained product is mixed with industrial oil, glycerine monooleate or glycerin monooleate on polymerised glycerin and TP ethanol amides.
EFFECT: increased emulsion stability due to reduced amount of free acid, partially formed as a result of hydrolysis of alkenyl succinic anhydride.
