    摘要： A cross-linked polymer-supported 4-(N-benzyl-N-methylamino) pyridine material and process for its preparation in high yield and having effective physical and catalytic properties. The polymer-supported catalyst is characterized by the suspension copolymerization of an organic phase containing the corresponding vinyl-substituted pyridine monomer, a styrene monomer, and a suitable cross-linking agent and free radical-generating catalyst in the presence of an aqueous phase containing a cellulose ether derivative as the stabilizing agent. A purified acid salt of the vinyl-substituted pyridine monomer useful in polymerizations and stable for storage as either a solid or an aqueous solution.

    摘要： 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.

    摘要： A process for preparing a 4-amino-1,2,4-(4H)triazole derivative compositions having the formula ##STR1## wherein R is hydrogen or an alkyl group containing from 1 to about 10 carbon atoms, which alkyl group can be additionally substituted by one or more aryl, heteroaryl, hydroxy, or alkenyl substituents, comprising the step of reacting hydrazine or an aqueous hydrazine solution with a carboxylic acid having the formula RCO.sub.2 H in the presence of an insoluble polymer containing acidic functional groups sufficiently strong to cause the reaction to proceed under mild conditions to produce a product of high yield and purity.
