Abstract: 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 ?73° C. to about 444° 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.

Abstract: Described are preferred processes for preparing alkenyl-substituted nitrogenous heterocycles such as vinylpyridines, which comprise reacting a corresponding methyl-substituted heterocycle with a C1 compound such as formadehyde in the vapor phase over a zeolite catalyst having acidic and basic catalytic sites. The preferred zeolite is a medium-pore zeolite, for example having a constraint index of about 0.5 to about 12. Processes of the invention can be conducted as facile, one-step syntheses utilizing relatively low ratios of alkyl-substituted starting heterocycle (e.g. &agr;-picoline or &ggr;-picoline) to formaldehyde while nonetheless achieving high selectivities and yields of the corresponding alkenyl compound.

Abstract: A process for the production of 3-cyanopyridine by ammoxidation of 2-methyl-1,5-pentanediamine to form 3-cyanopyridine, optionally carried out as an oxidative ammonolysis process.

Abstract: There are provided processes for preparing quinolines by vapor phase reaction of a substituted or unsubstituted aniline base, formaldehyde and a C.sub.2 -C.sub.4 aldehyde wherein the aldehydes:aniline base molar ratio is at least 2:1. More preferred processes of the invention achieve high selectivities and yields of 8-methylquinoline, and high conversions of the aniline base.
