Abstract:
A method of removing water soluble organics (WSO) and oil from a liquid containing water comprising:contacting the liquid with an effective amount of an organic ammonium salt having the formulaR.sup.1 R.sup.2 R.sup.3 N.sup.+ H X.sup.-whereR.sup.1 is a saturated or unsaturated alkyl group or an aryl group, or saturated or unsaturated alkyl group or an aryl group substituted with a heteroatom selected from the group consisting of N, O, S, P and halogen;R.sup.2, and R.sup.3 are independently H or a saturated or unsaturated alkyl group or an aryl group, or saturated or unsaturated alkyl group or an aryl group substituted with a heteroatom selected from the group consisting of N, O, S, P and halogen; andwhere R.sup.1 averages from about 4 to about 20 carbon atoms, and where R.sup.2, and R.sup.3 independently are H or average from about 1 to about 8 carbon atoms;X is selected from a group consisting of halogen and anions of protic acids; andseparating an oil phase containing said water soluble organics from a water phase in the absence of adding an acid having a pKa of less than or equal to 3.2.
