L. Cohen et al., QUANTITATIVE-DETERMINATION AND SEPARATION OF FREE OIL COMPONENTS IN LINEAR ALKYLBENZENE SULFONIC-ACIDS, Tenside, surfactants, detergents, 32(3), 1995, pp. 238-239
A liquid-solid extraction technique is described for the separation of
LAB (linear alkylbenzene) and sulphones contained in a linear alkylbe
nzene sulfonic acid. This method is less time consuming and easier to
carry out than the usual liquid-liquid extraction.
