A process for preparing diaryl sulfones, such as 4,4'-dichlorodiphenylsulfone is disclosed. The process comprises contacting an aryl compound with sulfur trioxide to provide a benzene sulfonic acid. The benzene sulfonic acid is coupled to additional aryl compound in the presence of a catalyst. During the coupling step, the additional aryl compound is continuously added while water is removed.

Process for converting a carboxamide to a thiocarboxamide includes reacting (a) a substrate that comprises a heteroatom-containing moiety and a carboxamide moiety with (b) a dialkyl dithiophosphate and/or a salt thereof. The heteroatom-containing moiety includes a heteroatom selected from the group consisting of N, O, and S. Processes for preparing piperidine-4-thiocarboxamide are described.

Disclosed herein are aminopyridinium cations and compositions containing these cations. Piperidino pyridinium cations and compositions containing these cations are also described. Ionic compositions, particularly liquid ionic compositions that contain the aminopyridinium cation or piperidino pyridinium cation are also described. Methods of enhancing the thermal stability of a compound, particularly an ionic compound, using the aminopyridinium or piperidino pyridinium cations, are also presented. Compositions having an expanded liquidus range of from about &#x2212;73&#xb0; C. to about 444&#xb0; C. are also described. Solvents, heat transfer fluids, and lubricants having improved thermal stability characteristics and an expanded and improved liquidus range are also disclosed.

Methods are provided for improving production of 3,5-diethyl-1,2-dihydro-1-phenyl-2-propylpyridine (DHP). In one illustrative embodiment, the methods involve controlling the rate of reaction and temperature of the reaction during formation of DHP. In another illustrative embodiment, the methods involve neutralizing the acid catalyst subsequent to DHP formation.

Processes for preparing a 4-(secondary or tertiary)aminopyridine are provided. The processes comprise reacting a 4-substituted pyridine base having a leaving group as the 4-substituent, with an activating agent so as to form a corresponding 1,4-substituted pyridine; reacting the 1,4-substituted pyridine with a primary or secondary amine to substitute an amino group at the 4-position, and thereby form a corresponding 1-substituted-4-(secondary or tertiary) aminopyridine, wherein the reacting is conducted in a substitution reaction medium essentially free from strong base; and treating the 1-substituted-4-aminopyridine compound to remove the 1-substituent and thereby form a product medium including the 4-(secondary or tertiary) amino-pyridine.

Supernucleophilic 4-substituted-pyridine catalysts, and processes useful for preparing same

Described are preferred processes for producing extrusion-granulated supernucleophilic 4-amino-substituted pyridine catalysts, and granular products obtainable thereform. Also described are preferred activation-substitution-deactivation processes for producing 4-aminopyridine compounds, which involve the use of acrylic acid or acrylamide or analogs thereof for activation, and substitution steps conducted under mild basic conditions in an excess of the amine reagent for 4-substitution. Such processes provide improved reacted masses which are more readily processed to recover the products in pure, heat-stable form. Further, described are processes for preparing 4-substituted-pyridines via pyridine betaines.

Described are preferred processes for preparing quaternary amine polymers of good color, comprising preparing a free base amine polymer by polymerizing a free base amine monomer in the presence of a water-soluble azo initiator, and subjecting the resultant polymer to quaternization conditions. Also described are unique, water-soluble quaternary amine polymers obtainable by such processes, and dye complexing polymer blends useful in the manufacture of detergents.

Described is a process for recovering phytic acid or phytic acid salt from a medium in which it is contained. This process includes contacting the medium with a solid-phase free base polymer having tertiary amine functions to adsorb the phytic acid or salt thereof. In one preferred mode, the medium to be treated also contains lactic acid, and separate fractions predominant in (i) lactic acid and (ii) phytic acid or phytic acid salt, respectively, are recovered. Also described are preferred processes for treating mediums to recover lactic acid therefrom, and a favored process for obtaining inositol directly by hydrolyzing phytic acid or phytic acid salt while adsorbed on a pyridine-containing polymer.
