摘要：A novel PIBSA-based surfactant is provided which has particular utility in themanufacture of water-in-oil explosive emulsions. The surfactant comprises the
esterification product of polyalk(en)yl succinic anhydride and an adduct of the formula:where R₁ is H or -CH₂-CH₂-OH and R₂ is selected from the group consisting of an acylgroup containing 8-20 carbon atoms and a hydroxy ethyl ester of a mono- or di-carboxylic acid containing from 8-25 carbon atoms. The compound can be distinguishedfrom the prior art PIBSA-based surfactants by virtue of the absence of any polyamine inits synthesis, the presence of an ester linkage and the absence of a salt linkage.
