Surface active compounds were prepared from malic acid by esterification with acyl chloride (II)a-d, of [palmitic, stearic, oleic, linoleic and mixed fatty acids of rice bran oil (RBO) (II)e], in the presence of pyridine as catalyst, forming (III)a-e , which are converted to anionic disodium salt (IV)a-e . The prepared a-acyl-oxysuccinic acid derivatives (III)a-e was oxypropenoxylated with various moles of propylene oxide (n= 2, 4, 6 and 8) to give (V-IX)a-d . These compounds were converted to nonionic surfactants with two terminal amide oxime groups (XV-XIX)a-d as molecular aggregations and surface active agents in aqueous media. The structures were confirmed by micro analysis, IR and 1H NMR spectra. The surface active pr...
