Abstract: JET FUELS WHICH HAVE BOTH A HIGH HEAT CONTENT AND AN ACCEPTABLE LOW TEMPERATURE VISCOSITY ARE PREPARED BY THE HYDROALKYLATION OF MONONUCLEAR AROMATIC HYDROCARBON FRACTIONS. BENZENE, TOLUENE, AND UNDEX EXTRACT, AND MIXTURES THEREOF, ARE THE PREFERRED STARTING MATERIALS. THESE ARE HYDROALKYLATED BY REACTION AT ABOUT 30*-250*C. UN DER SUPER-ATMOSPHERIC PRESSURE OF ABOUT 20-70 ATMOSPHERES OF HYDROGEN, THUS PRODUCING HYDROALKYLATES CONTAINING CYCLOALKYL-SUBSTITUTED BENZENES, METHYLCYCLOHEXYLSUBSTITUTE TOLUENS AND THE LIKE. THESE ARE FURTHER REDUCED TO THE CORRESPONDING CYCLOALKYL-SUBSTITUTED CYCLOHEXANES, TOGETHER WITH METHYLCYCLOHEXYL METHYLCYCLOHEXANES AND METHYLCYCLOHEXANE WHEN TOLUENE IS USED, AND THE REDUCTION PRODUCTS ARE ADJUSTED TO A FINAL DESIRED HEAT CONTENT AND LOW TEMPERATURE VISCOSITY BY STRIPPING OFF OR ADDING METHYLCYCLOHEXANE. THE PREFERRED CATALYST IS FINELY DIVIDED NICKEL ON A SUPPORT CONTAINING BOTH A ZEOLITE AND A SILICA-ALUMINA CRACKING CATALYST.

Abstract: AN INTERPOLYMER OF AN AN-ALKYLACRYLATE MIXTURE AND AN N-ALKANEDIOL DIMETHACRYLATE OF FROM 10 TO 18 CARBONS, SAID INTERPOLYMER HAVING A WEIGHT RATIO OF SAID N-ALKYLACRYLATE MIXTURE TO SAID ALKANEDIOL DIMETHACRYLATE OF BETWEEN ABOUT 99.5:0.5 TO 95:5 AND A MOLECULAR WEIGHT BETWEEN ABOUT 3000 AND 100,000 AND A MOLECULAR WEIGHT IN SAID N-ALKYL MIX IS OF AT LEAST 18 CARBONS AND AT LEAST 70 WT. PERCENT OF SAID ALKYL IS BETWEEN 20 AND 24 CARBONS INCLUSIVELY, THE C20 TO C24 ALKYL GROUP CONSISTING OF BETWEEN ABOUT 2 AND 65 WT. PERCRNT OF C20 ALKYL, BETWEEN ABOUT 18 AND 65 WT. PERCENT C22 ALKYL AND BETWEEN ABOUT 8 AND 35 WT. PERCENT C24 ALKYL; AND A WAXY HEAVY PETROLEUM FRACTION CONTAINING BETWEEN 4 AND 15 WT. PERCENT MACROCRYSTALLINE PARAFFIN WAX HAVING INCORPORATED THEREIN A POUR DEPRESSIG AMOUNT OF SAID INTERPOLYMER WHEREIN SAID INTERPOLYMER IS INITIALLY INTRODUCED IN THE WAXY HEAVY PETROLEUM FRACTION AT A TEMPERATURE ABOVE THE SOLUTION POINT OF THE MACROCRYSTALLINE WAX COMPONENT THEREIN.

Abstract: MOTOR FUEL COMPOSITION COMPRISING A MIXTURE OF HYDROCARBONS IN THE GASOLINE BOILING RANGE CONTAINING A NITROKETONIZED AMIDE CORRESPONDING TO THE FORMULA:

R-N(-R'')-(CH2)3-NH-R"

WHERE R, R'' OR R" IS A NITRODETONIZED GROUP HAVING FROM 4 TO 40 CARBON ATOMS. THE NITROKETONIZED AMIDE PROVIDES THE FUEL COMPOSITION WITH SUCH PROPERTIES AS RUST PROTECTION, CARBURETOR DE-ICING AND CARBURETOR DETERGENCY.
