    Abstract: EPIMERIC MIXTURES OF THE NOVEL LACTONE 3,6-DIHYDRO4,5-DIMETHYL-5-PHENYL-A-PYRONE MAY BE PREPARED BY REACTING HYDRATROPALDEHYDE WITH ACETALDEHYDE OR CROTONALDEHYDE. THESE COMPOUNDS ARE USEFUL IN V.I. STABILIZERS IN LUBE OILS, AND AS MONOMERS IN THE PREPARATION OF POLYESTERS. UNDER CERTAIN CONDITIONS A BY-PRODUCT COMPRISING A NOVEL LINEAR CONDENSATION PRODUCT, IDENTIFIED AS AN UNSATURATED AROMATIC ALDEHYDE, IS ALSO FORMED. THE RELATIVE PROPORTIONS OF THE NOVEL LACTONE AND UNSATURATED AROMATIC ALDEHYDES THAT ARE FORMED MAY BE CONTROLLED BY VARYING THE RATIO OF HYDRATROPALDEHYDE TO ACETALDEHYDE. THE USE OF CROTONALDEHYDE INSTEAD OF ACETALDEHYDE RESULTS IN THE FORMATION OF THE NOVEL LACTONE ALONE.

    Abstract: A PROCESS FOR HYDROISOMERIZATION OF DIMETHYLNAPHTHALENES (DMN''S), OR OF HYDROGENATED DMN''S COMPRISES CONTACTING SAID DMN''S OR HYDROGENATED DMN''S WITH HYDROGEN (E.G., 15-15000 P.S.I.G.) IN THE PRESENCE OF A COMBINATION OF A HYDROGENATION CATALYST AND A CALCIUM CONTAINING ZEOLITE CATALYST (PERFERABLY IN THE RANGE OF 10-100% CRYSTALLINE AND OF THE FAUGASITE STRUCTURE) AT A TEMPERATURE IN THE RANGE OF 300-500*C. (PREFERABLY IN VAPOR PHASE) AND AT A LIQUID HOURLY SPACE VELOCITY IN THE RANGE OF 0.25-10 (PREFERABLY 0.5-3). THE PREFERRED CALCIUM CONTAINING ZEOLITE HAS AN ATOMIC RATIO AL/SI IN THE RANGE OF 0.35-1.0 IN TGE ALUMINO-SILICATE FRAMEWORK. THE MORE PREFERRED ZEOLITE ARE SYNTHETIC FAUJASITES HAVING AN AL/SI FRAMEWORK RATIO IN THE RANGE OF 0.35 TO 0.65 (E.G., LINDE TYPE Y). WHEN THE FEED COMPRISES AT LEAST ONE MEMBER FROM THE 2,6- OR 2,7-DMN FAMILIES THE PROCESS CAN PRODUCE ISOMERS BOTH WITHIN AND BETWEEN THE 2,6- AND 2,7-DMN FAMILIES.
