Structure and properties The structural formula of the<unk>  anion is , where R is the 2-ethylhexyl group . The conjugate acid can be described as the twofold carboxylate ester of sulfosuccinic acid with 2-ethylhexanol. The compound is a white, wax-like, plastic solid, with an odor suggestive of octyl alcohol. It starts to decompose at about 220 °C. Solubility of dioctyl sodium sulfosuccinate in water is 14 g/L at 25 °C, increasing to 55 g/L at 70 °C. Solubility is better in less polar solvents: 1:30 in ethanol, 1:1 in chloroform and diethylether, and practically unlimited in petroleum ether (25 °C). It also is highly soluble in glycerol, although this is a rather polar solvent. It is also highly soluble in xylene, oleic acid, acetone, diacetone alcohol, methanol, isopropanol, 2-butanol, methyl acetate, ethyl acetate, furfurol, and vegetable oils. The ester groups are easily cleaved under basic conditions, but are stable against acids. Synthesis Sodium dioctyl sulfosuccinate can be obtained by treating dioctyl maleate with sodium bisulfite. The bisulfite anion adds to the double bond: : +
