Abstract: A process that can be used for sulfonating, sulfating, or sulfamating an organic compound is disclosed. The process can comprise, consist essentially of, or consist of, contacting the organic compound with sulfur trioxide under a condition sufficient to effect the sulfonation, sulfation, or sulfamation of the organic compound. The organic compound can be an aromatic compound, alcohol, carbohydrate, amine, amide, protein, or combinations of two or more thereof. The sulfur trioxide can be present in a complex comprising an inorganic support such as zeolite, silicalite, silica, titanosilicate, borosilicate, clay, aluminophosphate, and combinations of two or more thereof.

Abstract: The invention provides a high-yield method for producing onium salt derivatives useful as agents, such as acid-generators, employed in chemically amplified resists; and to provide novel onium salt derivatives. Reaction of an onium salt derivative containing a halide anion or a carboxylate anion with a sulfonic acid ester derivative or a phosphoric acid derivative provides an onium sulfate derivative or an onium phosphate derivative at high yield.

Abstract: The present invention relates to a sulfation process comprising the steps of: a) reacting a tertiary amine with a sulfation precursor having the formula: wherein R1 is C1-C22 alkyl, C7-C22 alkylenearyl, and mixtures thereof; to form an admixture comprising a quaternized amine and a sulfating species; and b) reacting a hydroxyl species with said admixture to form a sulfated hydroxyl species. The process of the present invention is adaptable to sulfating a wide range of alcohols including the hydroxyl unit which terminates a polyalkoxylate moiety which are prevalent in the area of surfactants, inter alia, alkyl ethoxy sulfates.
