    摘要: A process is disclosed for the preparation of anhydrous solutions of alkaline phenates in organic solvents, comprising the steps:(a) synthesis in water of alkaline phenates by the reaction of sodium sulphate or potassium sulphate with calcium hydroxide and a phenol of the general formula: ##STR1## wherein R and R', which may be the same or different from each other, are hydrogen atoms or linear alkyl groups having up to 4 carbon atoms, at a temperature substantially lower than 30.degree. C;(b) filtering the calcium sulphate;(c) quantitatively decalcifying the residual aqueous solution by the addition of an aqueous solution of NaOH or KOH, until a total concentration is reached which is at least equal to about 30% by weight of the total solution;(d) filtering the precipitated calcium hydroxide and alkaline sulphate;(e) extracting in countercurrent, at a temperature between 50.degree. and about 90.degree. C, the residual aqueous solution with at least one aprotic polar organic solvent; and(f) dehydrating the organic solution of the alkaline phenates.For the extraction in countercurrent of the aqueous residual solution, preferred organic solvents include .beta.-picoline, dimethylether of diethylene glycol, quinoline, tetrahydrofuran, dimethylsulphoxide, sulpholane and N-methyl-morpholine. If desired, a non-polar diluent (e.g., toluene) may also be present.

    摘要: The present invention relates to novel ionic liquids comprising a docusate, docusate variant, or other sulfonate anion. The ionic liquids may be conveniently made via, for example, metathesis. The ionic liquids are often hydrophobic and useful in many hydrocarbon compositions, polymer compositions, and in supercritical carbon dioxide applications. The ionic liquids are capable of hindering static electricity buildup in the hydrocarbon compositions and can therefore minimize flammability and/or explosiveness.
